1. Key Takeaways

The Forum of Small States was founded on 1 October 1992 under Singapore's convening initiative at the United Nations in New York, with an initial membership of 16 states: Bahrain, Barbados, Botswana, Cape Verde, Djibouti, Gabon, Honduras, Jamaica, Malta, Mongolia, Papua New Guinea, Singapore, Suriname, Tunisia, Uruguay, and Vanuatu. It was not created by a charter, not endowed with a secretariat, and not designed to issue binding resolutions. It was, from the outset, a deliberately minimalist architecture — a regular consultation mechanism among states sharing a single defining characteristic: a population below roughly ten million. That minimalism was itself a strategic choice. Singapore's diplomats understood that formal institutional structures attract formal institutional burdens: membership criteria debates, budget disputes, leadership contests, and entanglement with UN bureaucratic politics. An informal forum could grow quickly, pivot easily, and avoid the organisational pathologies that had burdened more ambitious multilateral experiments. By the mid-2020s, FOSS had grown to comprise 108 member states — a majority of the UN's total membership — making it the largest informal grouping within the UN system by number of participants (Singapore MFA, "Small States," 2026; FOSS Wikipedia, 1 October 1992 founding date).
Singapore's decision to found FOSS was not an act of multilateral altruism. It was a precise application of a long-standing logic in Singapore's foreign policy thinking: that small states, individually voiceless in Security Council chambers and individually marginal in General Assembly arithmetic, could acquire collective weight by aggregating their numbers and coordinating their positions. The operational design was executed by Chew Tai Soo, Singapore's Permanent Representative to the UN from 1991 to 1995, who served as FOSS's founding Chairman until 1995 and worked with the Permanent Representatives of Bahrain, Barbados, Cape Verde, Djibouti, Papua New Guinea, and Uruguay to launch the forum. Chew identified three concrete deficits facing small states at the UN: exclusion from key negotiations, insufficient information on UN activities, and chronic under-representation on the principal organs and specialised-agency boards. The FOSS founding was simultaneously a coalition-building tool, a reputation-building exercise, and a signalling instrument. By positioning itself as the convenor rather than simply the largest member of the small-state caucus, Singapore projected a self-image as a capable, responsible, and institutionally generous actor — a reputation it would draw upon in trade negotiations, climate discussions, and Security Council campaigns in subsequent decades.
The thematic evolution of FOSS from its 1992 founding to its 2026 operating mode mirrors the evolution of the global governance agenda itself. The forum's early years were dominated by procedural concerns: how should small states coordinate during General Assembly debates? how should they manage Security Council reform discussions? how should they present common positions at major UN conferences? By the 2000s, FOSS had developed topical working groups on trade, sustainable development, and maritime security. By the 2010s, climate justice — specifically the demand of small island developing states (SIDS) that major emitters be held accountable for loss and damage — had become FOSS's most visible external face, providing a platform through which Singapore could amplify the voices of Pacific and Indian Ocean micro-states whose existential climate vulnerability exceeded Singapore's own. By the 2020s, FOSS communiqués routinely addressed digital governance, pandemic preparedness, and the reform of multilateral institutions.
Singapore's role within FOSS has consistently been that of convener and facilitator rather than advocate-in-chief. This distinction is analytically important. Singapore does not share the climate-survival urgency of Tuvalu, Marshall Islands, or Maldives — it is a middle-income city-state with extensive coastal engineering capacity, not a low-lying atoll threatened by sea-level rise within a generation. It does not share the democratic-governance alignment of the Nordic small states (Iceland, Luxembourg, Malta) that are also FOSS members. It does not share the developmental constraints of the small Pacific or African states that make up the bulk of the forum's membership. Singapore's value-add lies precisely in this heterogeneity: it is large enough (relative to other FOSS members) to command diplomatic resources, institutionally capable enough to host and coordinate meetings, and politically non-threatening enough that it does not arouse suspicion of hegemonic intent the way a larger state convenor would.
The 30th Anniversary of FOSS in 2022 was marked by a High-Level Reception on the margins of the 77th UN General Assembly in New York on 22 September 2022, addressed by Prime Minister Lee Hsien Loong by video message and by Foreign Minister Vivian Balakrishnan in opening remarks delivered on 23 September 2022 (MFA reference 20220923-FOSS). The anniversary commemoration took the form of an informal reception with national statements rather than a formally adopted joint communiqué — consistent with FOSS's tradition of avoiding binding instruments — but the speeches reaffirmed small-state commitments to multilateralism, the UN Charter, and the rule of international law at a moment of unusual institutional stress. Russia's invasion of Ukraine in February 2022 had fractured the Security Council, generated an unprecedented Emergency Special Session of the General Assembly, and forced small states across the world to navigate the uncomfortable politics of great-power conflict. The FOSS 30th anniversary statements were therefore not a ceremonial exercise — they were a substantive signal that 108 states, many of them formally non-aligned, were prepared to reiterate their commitment to the principles of sovereign equality and territorial integrity that form the bedrock of the UN Charter's small-state protection framework. The 30th anniversary also coincided with Singapore's launch of two related initiatives: the "FOSS for Good" technical assistance package under the Singapore Cooperation Programme (FY2022–FY2023, since renewed through FY2026), and Digital FOSS, launched by Singapore's IMDA at a separate FOSS reception in Geneva on 24 October 2022.
The relationship between FOSS and the Alliance of Small Island States (AOSIS) illustrates the hub-and-spoke architecture that characterises Singapore's coalition diplomacy. AOSIS was founded in 1990, two years before FOSS, as a coalition of small island and low-lying coastal states with an explicit climate mandate. Its membership substantially overlaps with FOSS. Singapore's membership in FOSS but not in AOSIS (Singapore is not a small island state in the climate-vulnerability sense the term implies) positions it as a bridging actor: able to coordinate with AOSIS positions within the broader FOSS forum, channel information between the two groupings, and provide institutional support to climate-vulnerable FOSS members who are also AOSIS members without itself making the direct climate-justice advocacy claims that are AOSIS's institutional purpose. This hub-and-spoke positioning has enabled Singapore to project diplomatic influence at UNFCCC negotiations without committing to the specific loss-and-damage finance demands that SIDS prioritise.
Academic literature on small-state multilateralism has increasingly used FOSS as a case study in what Robert Keohane called the "Lilliputians' dilemma" — the paradox that small states individually lack power but collectively can constrain large states through normative pressure, numerical weight in majoritarian institutions, and the moral authority that accrues to the institutionally consistent and principled. FOSS has provided Singapore with a platform that no individual bilateral relationship could replicate: regular access to a group of states whose diplomatic priorities span every region, every major UN agenda item, and every major multilateral negotiation. Information gathered through FOSS coordination has been a consistent asset in Singapore's bilateral diplomacy with major powers, who routinely court FOSS members' votes in Security Council elections, treaty ratifications, and leadership contests.
Singapore's FOSS leadership has attracted little of the critical attention directed at its domestic governance record by Western academics and press commentators. The forum's structure — informal, consensus-based, non-binding — makes it difficult to level the charges of democratic deficit or hegemonic capture that critics level at more formally institutionalised coalitions. The closest analytical critique is the observation that Singapore's FOSS convenor role implicitly serves its own diplomatic brand more than it serves the material interests of FOSS's smallest and most vulnerable members: that Singapore uses the forum to amplify its own international standing while the Pacific SIDS and sub-Saharan African micro-states who make up the bulk of the membership remain as structurally marginalised in Security Council politics as they were before 1992. This critique has not been comprehensively rebutted but neither has it been rigorously documented with evidence of specific policy outcomes FOSS has blocked or delayed for its smaller members.

2. The Record in Brief

The Forum of Small States is the most consequential multilateral institution Singapore has directly created. Unlike the trade facilitation provisions Singapore introduced at the WTO's 1996 Singapore Ministerial — which were achievements of agenda-setting rather than institution-founding — and unlike Singapore's contributions to ASEAN, where it is one of ten founding members, FOSS is an institution that Singapore initiated, shaped, and has continuously led as convenor since 1992. Understanding FOSS requires understanding both what it is and what it is not.

FOSS is not a formal international organisation. It has no charter, no constitutive treaty, no legally recognised secretariat, and no binding dispute resolution mechanism. It does not issue resolutions with legal force. Its "decisions" are consensus communiqués — statements of shared position that carry moral and political weight but no enforceable obligation. This deliberate informality is the forum's operational strength: it allows rapid expansion (states can join without complex accession procedures), flexible agenda-setting (any topic relevant to small states can be introduced without amendment to a formal mandate), and resilience against institutional capture (no single state can dominate the forum's formal machinery, because there is no formal machinery to capture).

What FOSS provides is a regular, structured conversation among small states across regions, political systems, and economic development levels. The common denominator is population: FOSS is open to countries with a population of fewer than 10 million, though this threshold is a working norm rather than a binding criterion — the population of some members has grown beyond that level since they joined the group, and the figure is not codified in any constitutive treaty or formal admission procedure (Forum of Small States, Wikipedia summary of operating practice; MFA Singapore descriptive materials, retrieved 2026). This simplicity is by design. A more elaborate membership criterion — requiring particular governance standards, or regional representation quotas, or economic development thresholds — would have introduced exactly the political controversies that FOSS's founders sought to avoid.

Singapore's Permanent Mission to the United Nations in New York has served as FOSS's informal secretariat since 1992. This arrangement has created a durable institutional asymmetry: Singapore bears the administrative costs of coordination (meeting logistics, agenda-circulation, minute-keeping, outreach to potential members) in exchange for the reputational and informational benefits of being the permanent convenor. Critics of this arrangement have noted that it creates a principal-agent relationship in which Singapore, as secretariat, shapes what gets discussed and with whom. Defenders argue that Singapore has consistently used its convenor position to elevate the concerns of the forum's smallest and most vulnerable members, particularly Pacific and Indian Ocean SIDS, rather than to advance narrowly Singaporean interests.

The forum operates through two primary nodes: New York, where the UN Permanent Missions of member states meet regularly on the margins of the General Assembly, Security Council elections, and major UN conferences; and Geneva, where the UN Geneva hub and trade-related bodies (including the WTO and UNCTAD) have generated a secondary FOSS coordination nexus. The Geneva node is particularly significant for trade-policy coordination, given that many of FOSS's smallest members have limited WTO negotiating capacity and benefit from intelligence-sharing about major trading powers' positions. Singapore's WTO delegation has historically played a lead role in this Geneva coordination.

By 2026, FOSS's significance rested on three pillars. First, its sheer size: 108 member states representing a majority of UN membership meant that FOSS consultations on major General Assembly votes could constitute a critical informational input for state delegations navigating complex procedural or political choices (Singapore MFA, "Small States," 2026). Second, its thematic breadth: the forum had evolved from a procedural consultation mechanism into an agenda-setting body on climate justice, digital governance, UN reform, and pandemic preparedness — reflecting the expanding scope of multilateral governance itself. Third, its institutional continuity: unlike many UN caucuses and groupings that wax and wane with shifting diplomatic priorities, FOSS had maintained consistent operational activity for over three decades, giving it a legitimacy that new or episodic coalitions could not match.

3. Timeline 1992–2026

1 October 1992 — Forum of Small States founded in New York under Singapore's convening initiative. Singapore Permanent Representative Chew Tai Soo (1991–1995) drives the institutional design, working closely with the Permanent Representatives of Bahrain, Barbados, Cape Verde, Djibouti, Papua New Guinea, and Uruguay. Founding membership comprises 16 states — Bahrain, Barbados, Botswana, Cape Verde, Djibouti, Gabon, Honduras, Jamaica, Malta, Mongolia, Papua New Guinea, Singapore, Suriname, Tunisia, Uruguay, and Vanuatu — spanning all UN regional groups. Chew serves as FOSS's founding Chairman until 1995.

1993–1999 — FOSS establishes its operational rhythm: regular consultations on the margins of the UN General Assembly, coordination on Security Council election campaigns, and early discussions on trade liberalisation issues affecting small states. Singapore's Mission in New York provides informal secretariat functions. The forum grows incrementally as small states recognise the informational value of membership without incurring formal costs.

1996 — Singapore hosts the WTO Ministerial Conference. The "Singapore Issues" — trade and investment, trade and competition, government procurement transparency, and trade facilitation — are introduced at Singapore's initiative. FOSS members, many with limited WTO negotiating capacity, benefit from Singapore's intelligence-sharing about Ministerial dynamics. The Geneva FOSS node becomes more active as a trade-policy coordination platform.

2000–2005 — The UN Millennium Declaration (2000) and the Johannesburg World Summit on Sustainable Development (2002) generate new FOSS agenda items around sustainable development and small island state vulnerability. FOSS begins more structured engagement with AOSIS members on climate and environmental issues. Singapore's Singapore Cooperation Programme (SCP), expanding through this period, channels technical assistance to several FOSS member states, deepening the hub-and-spoke relationship between Singapore and smaller FOSS members.

2001–2002 — Singapore serves on the UN Security Council. FOSS coordination plays a role in mobilising the bloc votes needed for Singapore's election to the Council and in managing the diplomatic relationships needed for effective Security Council engagement, particularly in the aftermath of the 11 September 2001 terrorist attacks and the resulting Security Council activity on counter-terrorism.

2007–2009 — Global financial crisis generates FOSS discussions on small-state economic vulnerability and the adequacy of IMF and World Bank support mechanisms for small, open economies. Singapore's position as a financial centre gives it particular credibility in advocating for improved multilateral financial safety nets for small states.

2013 — WTO Trade Facilitation Agreement signed at the Bali Ministerial. The Agreement codifies priorities Singapore had introduced at the 1996 Ministerial, representing a seventeen-year institutional follow-through. FOSS members, many of whom benefit disproportionately from streamlined customs procedures and reduced trade transaction costs, are among the Agreement's natural beneficiaries.

2015 — Paris Agreement adopted at COP21. FOSS-member SIDS, coordinating through AOSIS, had pressed aggressively for a 1.5°C target rather than the 2°C floor backed by major emitters. The 1.5°C reference in the Paris Agreement's preamble and Article 2 represents a partial victory for small-island climate advocacy that FOSS's broader coalition capacity had helped amplify in the preceding decade.

2019 — Singapore Convention on Mediation opens for signature, with 46 signatories at launch. The Convention, negotiated over several years at UNCITRAL under Tommy Koh's active support, is hosted at a signing ceremony in Singapore. Several FOSS members are among the early signatories. The Convention demonstrates Singapore's continuing ability to translate multilateral norm entrepreneurship into binding international law.

2020–2021 — COVID-19 pandemic exposes the vulnerability of small states with limited health system capacity and high dependence on tourism and trade. FOSS consultations on pandemic response and vaccine access multiply. Tharman Shanmugaratnam's co-chairmanship (with Ngozi Okonjo-Iweala and Lawrence Summers) of the G20 High Level Independent Panel on Financing the Global Commons for Pandemic Preparedness and Response — established by the G20 in early 2021 — gives Singapore a central role in the global pandemic-financing accountability debate. (The Independent Panel for Pandemic Preparedness and Response convened by WHO was separately co-chaired by Helen Clark and Ellen Johnson Sirleaf, not by Tharman.) Singapore uses FOSS channels to distribute relevant findings to member states.

22 September 2022 — FOSS 30th Anniversary Reception held on the margins of the 77th UN General Assembly in New York. PM Lee Hsien Loong delivers a video message; FM Vivian Balakrishnan delivers opening remarks at the reception (MFA reference 20220923-FOSS). Russia's invasion of Ukraine in February 2022 had placed small-state diplomacy under acute stress — FOSS members were divided on how to respond to the Emergency Special Session of the UNGA and the subsequent resolutions calling on Russia to withdraw. The anniversary statements reaffirm commitment to UN Charter principles of sovereign equality and territorial integrity, a formulation designed to be acceptable across FOSS's politically diverse membership. Singapore launches the "FOSS for Good" technical assistance package under SCP (FY2022–FY2023); Digital FOSS is launched separately at a FOSS reception in Geneva on 24 October 2022.

2023–2024 — Lawrence Wong assumes the Prime Ministership of Singapore in May 2024. His foreign policy doctrine explicitly frames FOSS as part of Singapore's "strategic autonomy" toolkit — a mechanism for building coalitions that reduce small-state dependence on great-power patronage. FOSS coordination intensifies around UN Security Council reform debates and climate finance discussions ahead of COP29 (Baku, November 2024).

2025–2026 — The 2026 Strait of Hormuz crisis and associated geopolitical turbulence reinforces Singapore's argument within FOSS that small states need robust multilateral institutions as insurance against arbitrary great-power action. Singapore's FOSS convenor role is used to coordinate small-state positions on freedom of navigation, maritime security, and the legal framework for strait passage — areas where FOSS members' interests converge with Singapore's own existential interests in the unimpeded flow of trade through international waterways. The 14th FOSS Fellowship Programme (July 2025), the 15th (March 2026), and the 16th (April 2026) bring Permanent Representatives to Singapore for capacity-building visits during this period (MFA Singapore press releases).

4. The 1992 FOSS Founding — Singapore as Convenor

The founding of the Forum of Small States on 1 October 1992 was not an act of institutional improvisation. It was the product of a sustained intellectual and diplomatic campaign that had been building within Singapore's foreign policy establishment since the late 1980s. The key figure in translating that campaign into institutional reality was Chew Tai Soo, Singapore's Permanent Representative to the United Nations from 1991 to 1995, who took up his New York posting in 1991 and within roughly a year had moved from diagnosing the structural disadvantages facing small states at the UN to convening the first FOSS meeting. Chew served concurrently as Singapore's High Commissioner to Canada and Ambassador to Mexico during this period, and chaired FOSS until 1995.

Chew had observed a structural paradox in UN politics. The General Assembly formally operated on the principle of sovereign equality — one state, one vote. In procedural terms, Singapore, Iceland, and Tuvalu each had the same formal weight as the United States, China, and Russia. In practice, the exercise of that formal equality required resources that small states disproportionately lacked: large delegations capable of tracking every committee and working group simultaneously; legal advisers with deep expertise across the full range of UN agenda items; political capital sufficient to win the informal corridor negotiations that shaped outcomes before any formal vote was taken; and the credibility that comes from being seen as a serious, reliable diplomatic partner rather than a state whose UN presence was episodic or purely nominal. Chew distilled this paradox into three concrete deficits: small states were systematically excluded from negotiations, lacked in-depth information on UN activities, and were under-represented on the principal organs and specialised-agency boards of the UN.

The solution Chew identified was aggregation. Individually, a small state with a two-person UN delegation could not be present everywhere or follow everything. Collectively, a hundred small states could divide the tracking labour among their missions, pool intelligence about major powers' negotiating positions, coordinate voting intentions in advance of key General Assembly decisions, and — crucially — present a common front on the procedural reforms that would make the General Assembly more genuinely reflective of the interests of its majority membership. Chew worked closely with the Permanent Representatives of Bahrain, Barbados, Cape Verde, Djibouti, Papua New Guinea, and Uruguay to translate this diagnosis into the founding architecture, and FOSS was inaugurated on 1 October 1992 with sixteen founding members. The intellectual frame for the project drew on a broader Singapore foreign-policy tradition associated with figures such as Tommy Koh, Kishore Mahbubani, and Chan Heng Chee (Singapore's first Permanent Representative to the UN, 1989–1991, and subsequently Singapore's Ambassador to the United States, 1996–2012), but the operational design and the founding chairmanship of FOSS belong specifically to Chew Tai Soo.

The design choices made in 1992 reflected hard-won lessons from earlier multilateral coalition experiences. The Non-Aligned Movement, founded in 1961, had demonstrated the power of collective third-world solidarity but had also demonstrated the institutional dysfunctions that resulted from ideological overreach, Cold War instrumentalisation, and the failure to translate aggregate voice into specific policy outputs. The Group of 77, established in 1964, was larger still but suffered from the same problem of aggregating too many contradictory interests under a single political umbrella. Both organisations had lost effectiveness as their membership grew and their lowest-common-denominator politics made it increasingly difficult to produce coherent positions on any contentious issue.

FOSS deliberately avoided these pitfalls. It was not ideologically defined — it had no position on capitalism versus socialism, no stance on Cold War alignments, no developmental ideology of the sort that had fractured the New International Economic Order debates of the 1970s. Its membership criterion — small population — was purely empirical, creating no requirement that members share political systems, economic models, or foreign policy orientations. This breadth made it more inclusive but also meant it could not mobilise around contentious normative questions: FOSS could not, for example, take collective positions on human rights or democratic governance without immediately fracturing across its membership.

The decision to locate FOSS's operational centre in New York — where the UN General Assembly, Security Council, and most major UN conferences took place — rather than Geneva or elsewhere reflected a clear sense of strategic priority. The General Assembly was the institution where small-state numerical weight was most directly convertible into diplomatic currency, and the Security Council elections held through the General Assembly were the arena where organised small-state coordination could produce the most concrete and immediate results. FOSS coordination on Security Council election campaigns — essentially the collective management of small-state bloc votes in elections for the ten non-permanent Security Council seats — became one of the forum's most practically consequential activities from the 1990s onward.

Singapore's own decision to seek Security Council membership illustrated the value of the FOSS platform it had built. Singapore served on the Security Council in 2001–2002. (Singapore had not previously served on the Council; the widely cited "1979–1980" term sometimes attributed to Singapore in informal sources is not borne out by the UN Security Council's official rolls, which record Bangladesh and the Philippines as Asia-Pacific elected members for 1979–1980.) A city-state of five to six million people cannot win a General Assembly Security Council election without broad multilateral support. FOSS membership and the credibility accrued through FOSS convenor activities were directly convertible into the bloc votes needed for Singapore's 2001–2002 candidacy, and Singapore's UN Mission continued through the 2020s to participate actively in Council reform debates without, at the time of writing, having formally launched a campaign for a second non-permanent term.

The 1992 founding also coincided with a significant moment in Singapore's broader diplomatic biography. Tommy Koh was simultaneously leading the preparation of the Earth Summit (June 1992) in his capacity as Secretary-General of the United Nations Conference on Environment and Development — a role that demonstrated Singapore's capacity to supply senior diplomatic leadership at the highest levels of the UN system. The FOSS founding was thus one element of a coherent institutional strategy rather than an isolated initiative: Singapore was simultaneously building regional commitments through ASEAN, global trade commitments through the GATT/WTO process, and now a cross-regional small-state coalition through FOSS.

5. The Architecture — 100+ Member States, Geneva and New York Hubs

FOSS's architecture is best understood not as a formal organisation with a fixed structure but as a diplomatic infrastructure — a set of recurring interactions, shared norms, and information-distribution channels that function because participants find them useful and because Singapore invests the administrative resources needed to maintain them. The architecture has two primary geographic expressions (New York and Geneva), several functional expressions (General Assembly coordination, Security Council election management, WTO trade intelligence, climate-policy signalling), and one permanent institutional expression (Singapore's Permanent Missions in New York and Geneva as informal convenors).

New York Node

The New York hub is the original and primary locus of FOSS activity. The UN General Assembly meets annually from September, and the associated High-Level General Debate — attended by heads of state, foreign ministers, and senior officials from all member states — provides the natural gathering point for FOSS consultations. Singapore's Mission in New York organises regular FOSS meetings on the margins of the General Assembly, the UNGA Third Committee (Social, Humanitarian, and Cultural), and major Security Council-related events. These meetings typically involve the permanent representatives of member states sharing intelligence about upcoming votes, discussing coordination strategies, and identifying areas of shared interest that could be developed into common positions.

The size of the forum — over one hundred members — creates a collective informational resource that no individual mission can replicate. Pacific island states with one-person missions in New York, tracking only the agenda items most directly relevant to their national interests, benefit enormously from access to the broader informational sweep of Singapore's much larger and better-resourced Mission. The information flows in both directions: Singapore gains access to perspectives from across the Global South and from regions — West Africa, the Eastern Caribbean, the Pacific islands — where its bilateral diplomatic presence is limited.

Security Council election coordination is one of FOSS's most practically consequential functions. The ten non-permanent seats on the Security Council are contested among UN member states in regional groups, with elections held by the General Assembly. Winning a Security Council seat typically requires securing a two-thirds majority of votes cast — roughly 129 votes in a 193-member General Assembly. For a state without a large bilateral aid programme or great-power patronage network, mobilising that majority requires organised multilateral coalition support. FOSS coordination has historically been a significant factor in Security Council election outcomes, both for Singapore's own 2001–2002 candidacy and for those of other FOSS members.

Geneva Node

The Geneva node developed organically through the 1990s and 2000s as the WTO, UNCTAD, and other UN Geneva agencies grew in importance as sites of substantive multilateral negotiation affecting small states. Geneva's particular value is in trade policy: WTO negotiating rounds, dispute settlement proceedings, and the ongoing regulatory work of WTO committees all affect small states significantly, but many FOSS members lack the negotiating capacity to participate effectively in Geneva-based processes without assistance.

Singapore's WTO delegation in Geneva has historically served as a de facto intelligence-sharing hub for FOSS members on trade policy. Singapore's status as a major trading economy — consistently one of the world's most trade-open states by GDP ratio — gives it a substantive stake in WTO outcomes that goes beyond the symbolic. Its delegation's close tracking of WTO procedural and substantive developments, and its willingness to share that intelligence with FOSS members in Geneva-based consultations, represents a practical benefit that has reinforced the forum's cohesion.

The Geneva node has also been significant in the context of UNCTAD's work on small and developing states. UNCTAD produces regular reports on the trade and development challenges facing small states, and its data on trade dependency, commodity exposure, and financing gaps provide the evidentiary foundation for many FOSS positions in WTO and UN negotiations. Singapore has used UNCTAD data selectively to reinforce arguments about the vulnerability of small states in multilateral trade discussions — a strategic deployment of multilateral institutional research in support of FOSS coalition positions.

Membership Scale and Diversity

By the mid-2020s, FOSS membership had grown to 108 states drawn from every UN regional group: African states (including small island states like Seychelles and Cabo Verde as well as small mainland states like Djibouti, Eswatini, Botswana, Gabon, and Equatorial Guinea); Asian states (Singapore, Bhutan, Brunei, Bahrain, Maldives, Mongolia, Timor-Leste, and others); European states (Luxembourg, Iceland, Malta, Cyprus, Montenegro, Slovenia, and others); Latin American and Caribbean states (Barbados, Belize, Honduras, Jamaica, Trinidad and Tobago, Suriname, Uruguay, and others); and Pacific states (Fiji, Papua New Guinea, Solomon Islands, Tonga, Tuvalu, Vanuatu, and others). The Singapore MFA confirms the 108-member total in its small-states descriptive materials and in successive Forum of Small States Fellowship Programme press releases issued through 2026.

This geographic breadth gives FOSS a cross-regional legitimacy that region-specific groupings cannot match. A statement by FOSS carries the implicit endorsement of small states from Africa, Asia, Europe, Latin America, and the Pacific simultaneously — a legitimating spread that amplifies its weight in General Assembly debates. It also creates diplomatic complexity: coordinating positions across states with such different interests, governance structures, and external relationships requires constant management and a disciplined commitment to agenda items on which genuine convergence is possible.

6. The Topical Areas — Climate, Trade, UN Reform, Maritime Security

FOSS began as a procedural coordination mechanism and evolved into a substantive policy forum. By 2026, four topical areas dominated its agenda: climate change and climate justice; trade facilitation and WTO reform; UN institutional reform including Security Council reform; and maritime security and freedom of navigation.

Climate Change and Climate Justice

Climate change became FOSS's most publicly visible agenda item through the 2010s, driven by the existential urgency of the Pacific and Indian Ocean small island members for whom sea-level rise, intensifying tropical cyclones, and ocean acidification represent literal threats to national survival. The Alliance of Small Island States (AOSIS), founded 1990, comprises the climate-frontline states within the broader FOSS membership, and FOSS has functioned as an amplifier of AOSIS positions within the broader UN membership.

The key climate-justice demands that FOSS members — particularly SIDS — have pressed at successive UNFCCC conferences centre on three issues: first, the 1.5°C target versus the 2°C target (SIDS argue, with scientific support, that 2°C of warming produces catastrophic outcomes for low-lying atolls); second, loss and damage finance (the demand that major historical emitters pay compensation for climate damages already suffered by small vulnerable states that have contributed minimally to historical emissions); and third, adaptation finance (the provision of funds for vulnerable states to adapt their infrastructure, agriculture, and water systems to climate changes already locked in). FOSS consultations have regularly produced coordinated small-state positions on all three of these issues at COP negotiations.

Singapore's position within FOSS on climate is structurally complex. Singapore is itself a significant per-capita emitter and a major hub for aviation and maritime transport — sectors that contribute substantially to global emissions. Its coastal engineering capacity (the Coastal Protection and Flood Management Programme, seawall construction) means it faces climate adaptation challenges very different in nature from those of low-lying Pacific atolls. Singapore has committed to net-zero emissions by 2050 and has introduced a carbon tax (expanded from S$5/tonne in 2019 to a trajectory toward S$50–80/tonne by 2030). Within FOSS, Singapore's role is therefore as amplifier and facilitator of SIDS climate advocacy rather than as a co-victim: it provides diplomatic resources, institutional continuity, and international credibility to SIDS positions without making the same direct appeals to climate justice that SIDS members make (see SG-N-18).

Trade Facilitation and WTO Reform

Small states are structurally disadvantaged in the WTO system. Consensus-based decision-making means that any member can block progress; the major trading powers have disproportionate leverage through the volume of their market access offers; and small states with limited export diversity are particularly exposed to protectionist actions by large partners. FOSS coordination on trade policy has focused on three areas: supporting the implementation of the Trade Facilitation Agreement (TFA, signed 2013, in force 2017); advocacy for special and differential treatment provisions that accommodate small states' limited regulatory and enforcement capacity; and resistance to agricultural subsidy regimes maintained by developed-country WTO members that undercut small-state agricultural exporters.

Singapore's relationship with WTO trade advocacy is complicated by its own trade interests. As a highly open economy with no significant agricultural sector and a dominant services orientation, Singapore's trade priorities — transparent procurement, investment facilitation, digital trade rules — do not always align with those of the agricultural-exporting small states that make up a significant portion of FOSS's membership. Managing these divergent interests within FOSS has required Singapore to act more as a process facilitator — helping small states articulate their own positions clearly and coordinate their negotiating strategies — rather than as a substantive leader on agricultural trade reform where its national interests point in different directions.

UN Institutional Reform

Security Council reform has been a recurring FOSS agenda item since the 1990s. The Security Council's composition — five permanent members with veto power (P5) plus ten non-permanent members elected for two-year terms — was designed in 1945 to reflect the post-World War II balance of power and has not been changed since. Reform proposals have multiplied: the G4 (Germany, Japan, India, Brazil) have sought additional permanent seats; the African Union has demanded African permanent representation; and smaller states have generally favoured either expanding the non-permanent category or reducing the P5 veto. FOSS has not adopted a single reform proposal but has consistently advocated for increasing the representation of small and developing states in UN decision-making — a position that reflects the structural interests of its membership regardless of the specific formula adopted.

Singapore's own reform position has been characteristically pragmatic. It supports expanded Security Council representation in principle but resists any reform that would further entrench veto-like mechanisms, since the existing veto creates exactly the kind of great-power exception to rule-based governance that Singapore's small-state doctrine identifies as threatening. Singapore has used FOSS platforms to press for greater transparency in Security Council working methods — a reform that does not require Charter amendment and that incrementally improves small-state access to Security Council deliberations — as well as for improvements in the General Assembly's procedural efficiency, which disproportionately benefits the smaller missions with limited staff to track lengthy debates.

Maritime Security and Freedom of Navigation

Maritime security has been a FOSS agenda item of particular interest to Singapore since the late 1990s, reflecting Singapore's unique position as a city-state whose entire economic model depends on the unimpeded movement of shipping through the Strait of Malacca and Singapore Strait, and through the wider Indo-Pacific sea lanes. FOSS's membership includes many small island and coastal states whose economies are similarly dependent on maritime connectivity — Pacific island states whose only surface connection to global markets is by sea, small Caribbean states whose tourism and goods imports flow entirely through maritime channels, and small African coastal states whose port revenues are a primary source of public finance.

Singapore has used FOSS consultations to build common small-state positions on: the legal framework for innocent passage and transit passage through straits under UNCLOS (see SG-F-10); counter-piracy and maritime security cooperation, particularly in the Malacca Strait and Gulf of Aden; and the governance of international shipping routes in the context of climate-driven Arctic route development. These positions have been expressed in FOSS communiqués and in coordinated statements by FOSS members at IMO and UNCTAD proceedings. The practical value of this coordination for Singapore is that it converts what might otherwise appear as narrowly Singaporean commercial interest (keep the shipping lanes open) into a broad multilateral principle (maritime connectivity is a shared small-state public good) — significantly strengthening Singapore's normative position in international maritime governance debates.

7. The 30th Anniversary Architecture (2022)

The Forum of Small States' 30th Anniversary in 2022 was marked by a High-Level Reception convened on the margins of the 77th UN General Assembly in New York on 22 September 2022, with Foreign Minister Vivian Balakrishnan delivering opening remarks at the reception (MFA reference 20220923-FOSS) and Prime Minister Lee Hsien Loong delivering a video message to the gathering. Consistent with FOSS's tradition of avoiding formal instruments, the anniversary did not produce a legally binding joint communiqué; instead, national statements by the convenor and member states affirmed shared commitments to multilateralism and the UN Charter at a moment of acute geopolitical stress, following Russia's invasion of Ukraine in February 2022 and the subsequent fracturing of Security Council functionality.

The 2022 anniversary was not merely ceremonial. By 2022, FOSS faced two structural challenges that the forum's founders could not have fully anticipated in 1992. The first was the erosion of the multilateral order itself: US-China rivalry had paralysed the WTO Appellate Body, the Security Council was deadlocked on Ukraine, vaccine nationalism had exposed the WHO's enforcement limits, and IMF quota reform remained stalled. These erosions directly threatened the rule-based framework on which small states depended — the same framework that had motivated the FOSS founding in the first place.

The second challenge was the growing divergence in the political orientations of FOSS members. In 1992, the forum had been founded at the end of the Cold War, in a moment of unusual consensus about the value of multilateralism and the UN system. By 2022, FOSS's membership spanned democracies and authoritarian states, states that had supported the UNGA Emergency Special Session resolutions on Ukraine and states that had abstained or voted against them, states with close ties to China and states with close ties to the United States and Europe. Building consensus across this political diversity on a statement that addressed Russia's invasion — even in purely UN Charter language — was a significant diplomatic achievement.

The communiqué's framing around "sovereign equality," "territorial integrity," and "the rule of international law" was carefully calibrated to attract the broadest possible endorsement within FOSS's diverse membership. It avoided direct condemnation of Russia — a framing that several FOSS members with economic or political ties to Moscow could not have endorsed — while affirming the principles that Russia's invasion had violated. This calibration illustrates the precise kind of diplomatic craft that FOSS's consensus-based, minimalist architecture enables: it produces statements that carry moral weight and reflect genuine convergence on principles without requiring members to take positions that their bilateral relationships with major powers prevent them from taking.

The anniversary meeting also served as a platform for Singapore to articulate its vision for FOSS's next phase. Singapore's statements at the meeting — through Foreign Minister Vivian Balakrishnan and through Singapore's UN Permanent Representative — framed the forum's continued relevance around three themes: the defence of international law and the rules-based order against great-power erosion; the need for small states to invest in digital and climate resilience to manage the compound crises of the 2020s; and the importance of maintaining FOSS's politically diverse membership as a source of legitimacy that more ideologically cohesive groupings cannot claim.

The 2022 architecture also expanded FOSS's functional reach through two announced sub-tracks: the "FOSS for Good" technical assistance package under the Singapore Cooperation Programme (FY2022–FY2023, since renewed through FY2026), and Digital FOSS, launched by Singapore's IMDA at a separate reception in Geneva on 24 October 2022 as a new pillar of engagement on digital governance issues of relevance to small states. A further consultative subset — the Small States Group (SSG), comprising 55 of the 108 FOSS members — was constituted in 2023 to advance positions on UN reform and the Pact for the Future. Together these instruments represented the maturation of FOSS from a purely reactive consultation mechanism into a more proactive policy-development platform, though they remain consultation tracks under Singapore's convenor leadership rather than formally constituted working groups with independent secretariats.

Singapore's investment in the 30th anniversary was not merely institutional nostalgia. By 2022, FOSS had become a significant asset in Singapore's broader diplomatic toolkit in ways that were not fully apparent at the forum's founding. The 100+ member network was an informational resource, a legitimating coalition for Security Council candidacies, a platform for amplifying small-state positions at major multilateral negotiations, and — increasingly — a vehicle for Singapore to project influence in regions (Pacific, Caribbean, small African states) where it had limited bilateral diplomatic presence.

8. The Climate-Justice Frame — FOSS as SIDS Amplifier

The most significant evolution in FOSS's public identity over the first three decades of its existence has been its emergence as an amplifier for the climate-justice advocacy of small island developing states (SIDS). This evolution was not inevitable — the forum was founded for procedural coordination purposes, not climate advocacy — and it reflects the degree to which climate change has come to dominate the multilateral agenda in ways that its 1992 founders could not have fully anticipated.

The logic of FOSS as SIDS amplifier is structural. AOSIS comprises 39 member states (of which 37 are UN member states; Cook Islands and Niue participate within UN agencies without full UN membership), representing the most climate-vulnerable populations in the world but accounting for less than one percent of global greenhouse gas emissions (AOSIS official membership records; Alliance of Small Island States, aosis.org, 2026). At UNFCCC negotiations, AOSIS states have consistently pressed for: binding commitments to limit warming to 1.5°C; a dedicated loss and damage finance mechanism; enhanced adaptation finance exceeding the commitments made by developed countries under the 2009 Copenhagen Accord and subsequent agreements; and reformed Green Climate Fund governance that gives developing-state recipients greater control over fund allocation. These demands have been persistently resisted by major emitters and by developed-country contributors who balk at the open-ended financial liabilities implied by loss and damage commitments.

Within FOSS, AOSIS members constitute a significant bloc. FOSS meetings on the margins of UNGA and in the lead-up to annual COP sessions have provided a platform for AOSIS members to build broader small-state support for their positions — not just among the 39 AOSIS members themselves, but across the wider FOSS membership, which includes small states that are not SIDS but that share an interest in the principle that powerful states should be accountable for the externalities they impose on vulnerable ones. This broader small-state solidarity — transcending the strict AOSIS membership — gives AOSIS positions at UNFCCC a legitimating weight they would not carry if they were advanced by AOSIS alone.

Singapore's role as the convenor of the amplification platform is analytically interesting precisely because Singapore is not itself a climate-justice claimant in the same sense as Pacific SIDS. Singapore's coastal exposure is real — the government has committed S$100 billion over the long term to coastal protection and drainage enhancement — but its technological and financial capacity to manage that exposure dwarfs that of Tuvalu, whose entire national territory stands less than five metres above sea level, or Kiribati, whose government has explored purchasing land in Fiji as contingency against complete inundation. Singapore's presence at FOSS climate discussions therefore represents a form of diplomatic solidarity that is not entirely separable from strategic interest: by positioning itself as a champion of SIDS climate-justice demands, Singapore builds goodwill with the Pacific states whose UN votes it cultivates for Security Council elections and other multilateral contests.

The limits of this solidarity are also visible. Singapore has been cautious about endorsing the most ambitious interpretations of the loss and damage principle — specifically, the idea that historical emitters bear legal liability for climate damages suffered by non-emitting states, which would create significant financial obligations. Singapore's own carbon tax trajectory and its hosting of major oil trading and shipping companies create commercial sensitivities that make uncaveated endorsement of the strongest loss-and-damage formulations diplomatically complex. Singapore's characteristic approach has been to express rhetorical solidarity with SIDS climate concerns while supporting procedural and institutional mechanisms — the establishment of the Santiago Network on loss and damage at COP25 in 2019; the COP27 decision in November 2022 to create a dedicated Loss and Damage Fund — without committing Singapore itself to specific financial contributions to those mechanisms. (Singapore's national statement at COP27 was delivered by Minister for Sustainability and the Environment Grace Fu on 15 November 2022, not by Foreign Minister Vivian Balakrishnan; the statement called for interim targets across mitigation, adaptation, loss and damage, and finance.)

The COP27 decision in Sharm el-Sheikh (November 2022) to establish a Loss and Damage Fund was the most significant victory for SIDS climate advocacy in a decade, and FOSS coordination in the months preceding COP27 was one of the factors that helped build the political momentum for that outcome. Singapore, represented at the High Level Segment by Minister for Sustainability and the Environment Grace Fu on 15 November 2022, supported procedural progress on loss and damage while preserving its long-standing reservation about open-ended financial liabilities. Foreign Minister Vivian Balakrishnan's substantive engagement on the climate-justice frame around this period was conducted at the UN General Assembly (his 24 September 2022 UNGA national statement) and at adjacent fora rather than at the COP itself.

9. The Hub-and-Spoke Role of Singapore Diplomacy

The most analytically distinctive feature of Singapore's FOSS leadership is not its advocacy on specific policy issues but its structural role as the hub of a hub-and-spoke diplomatic network that links the disparate membership of the forum to each other and to the broader multilateral system. Understanding this role requires distinguishing between Singapore as a small state itself (a participant in FOSS with interests it seeks to advance) and Singapore as the FOSS convenor (an institutional actor that maintains the platform on which all member states interact).

As a small state, Singapore participates in FOSS to advance identifiable national interests: Security Council election support, WTO trade intelligence, legitimation of its foreign policy positions, and access to a broad network of bilateral relationships that Singapore's limited diplomatic footprint would not otherwise sustain. Singapore maintains full-scale diplomatic missions in fewer than thirty countries — a much smaller bilateral network than its economic prominence suggests would be warranted — and the FOSS multilateral platform supplements this bilateral network by providing a regular point of contact with over one hundred small states whose bilateral relationships with Singapore range from warm to essentially non-existent.

As the FOSS convenor, Singapore bears costs that are not reducible to direct national interest calculation: the administrative burden of coordinating meetings, circulating agendas, managing diplomatic logistics for a hundred-state forum, and maintaining the institutional knowledge and relationship management that keeps the forum operational between formal meetings. These costs are absorbed by Singapore's MFA budget and by the capacity of Singapore's Permanent Missions in New York and Geneva — resources that represent a sustained public investment in institutional leadership.

The hub-and-spoke architecture creates an asymmetric information structure that benefits Singapore. As the organiser of FOSS consultations, Singapore's Mission sees the full range of member states' positions and concerns before any formal coordination session. This advance intelligence about the diplomatic priorities of over a hundred small states — spanning every region and political orientation — is a significant asset in Singapore's bilateral engagements with major powers, who regularly seek Singapore's read on Global South positions. When a major power government wants to understand how small African or Pacific states are likely to vote on a sensitive Security Council election or a contentious General Assembly resolution, Singapore is among the first interlocutors it calls.

The Singapore Cooperation Programme (SCP), established in 1992 in the same year as FOSS, deepens this hub-and-spoke relationship through technical assistance. By the FY2024/2025 training calendar, SCP had trained more than 150,000 foreign officials from over 170 countries since its 1992 launch, running approximately 300 courses and workshops a year and training close to 7,000 officials annually across thematic tracks in environmental sustainability, national resilience, leadership and governance, economic development, public health, transport connectivity, and digital innovation (Singapore Cooperation Programme, scp.gov.sg; SCP Calendar FY2024/2025). A significant proportion — though not publicly disaggregated by Singapore MFA — of these participants come from FOSS member states, and the 2022 "FOSS for Good" technical assistance package was specifically designed as a FOSS-only sub-track within the wider SCP framework. This capacity-building investment creates durable person-to-person networks between Singapore's civil service and the civil services of partner countries — networks that operate in parallel with the more formal diplomatic FOSS coordination and that provide Singapore with additional channels of influence and intelligence. A Fijian Ministry of Finance official who has attended a Singapore Public Service training programme is more likely to reach out to a Singapore counterpart for advice on multilateral negotiations than one who has not; these individual-level relationships aggregate into Singapore's broader soft-power infrastructure.

The hub-and-spoke model also has structural weaknesses that Singapore's critics identify. The most fundamental is the dependency it creates: if Singapore were to reduce its investment in FOSS coordination — if its MFA were to face budget constraints, or if a change in political leadership were to deprioritise multilateral institution-building in favour of bilateral great-power management — the forum's operational capacity would deteriorate rapidly. The absence of a formal secretariat means that there is no institutional memory, no independent staff, and no autonomous budget that would allow FOSS to continue operating without Singapore's active support. This dependency is not accidental; it is a product of the design choices made in 1992. But it means that FOSS's institutional durability is ultimately contingent on Singapore's continued willingness to invest in it.

10. Comparative Lens — FOSS vs. G-77, AOSIS, and the Commonwealth Small States

Situating FOSS in the landscape of small-state and developing-state multilateral groupings illuminates both its distinctive strengths and its structural limitations. The three most instructive comparators are the Group of 77 (G-77), the Alliance of Small Island States (AOSIS), and the Commonwealth's small states network.

FOSS vs. G-77

The Group of 77, founded in 1964, is the largest intergovernmental organisation of developing nations in the UN system. By 2026 it had grown to 134 member states (the name is a historical artifact of its founding membership). G-77 provides a comprehensive developing-country coalition across all major UN agenda items, issuing joint positions at UNGA and major UN conferences and negotiating as a bloc in many UN processes. Singapore is not a G-77 member — it graduated from developing-state status and G-77 membership as its economy advanced — which creates a structural boundary between Singapore's FOSS role and the G-77 coalition.

The key difference between FOSS and G-77 is specificity. G-77 aggregates all developing states regardless of size; its positions must accommodate the interests of large developing economies (China, India, Brazil, Indonesia, Nigeria) alongside those of the smallest island states. This leads to the lowest-common-denominator problem: G-77 positions often reflect the interests of the larger developing states more than those of the smallest members, because the large states have greater negotiating capacity and can shape the coalition's positions in their favour. FOSS, by contrast, is limited to small states, which creates a more genuinely common-interest pool: all FOSS members share the structural characteristics of limited negotiating capacity, high external dependence, and vulnerability to decisions made by larger powers without small-state input.

The G-77 and FOSS are not competing but complementary: most FOSS members are also G-77 members, and FOSS consultations often help small G-77 members coordinate their positions within the larger G-77 coalition. Singapore's external status relative to G-77 — it is the FOSS convenor but not a G-77 member — creates an interesting position: Singapore can facilitate small-state coordination within G-77 through FOSS channels without itself bearing the obligations of G-77 membership.

FOSS vs. AOSIS

The AOSIS-FOSS relationship has been discussed above in the context of climate-justice amplification. The key analytical point is that AOSIS and FOSS serve complementary functions that neither could serve alone. AOSIS provides the focused, expert, and morally authoritative voice of the climate frontline — states whose survival is directly at stake — and this existential credibility is irreplaceable in climate negotiations. But AOSIS's membership of 39 states is a minority of UN membership, and its positions at UN negotiations can be outvoted or marginalised by coalitions of larger and wealthier states. FOSS's 100+ membership provides AOSIS positions with broader political backing while AOSIS provides FOSS with a morally compelling climate narrative that enhances the forum's overall profile.

Singapore's bridging position between AOSIS and FOSS reflects a broader pattern in its multilateral strategy: using its own non-membership in specific advocacy coalitions (it is neither a G-77 nor AOSIS member) to serve as an honest broker and information channel between those coalitions and the major powers, collecting informational and reputational benefits on both sides of each interface.

FOSS vs. Commonwealth Small States

The Commonwealth of Nations includes a substantial number of small states — approximately 30 of its 56 members have populations below one million — and the Commonwealth Secretariat has developed extensive programmes for small-state capacity building, technical assistance, and advocacy in multilateral forums. The Commonwealth's small-state network differs from FOSS in two important ways: it is geographically and historically bounded by the Commonwealth membership (former British colonies and dependencies), and it has a formal institutional structure (the Commonwealth Secretariat in London) with a dedicated small-states programme. Singapore is a Commonwealth member but rarely invokes the Commonwealth framework in its multilateral strategy, reflecting both the organisation's declining strategic relevance and Singapore's preference for UN-based multilateralism.

The coexistence of FOSS and the Commonwealth small-states network means that many small states participate in both, and that there is occasional redundancy in their consultation processes. Singapore has generally been content with this overlap, since FOSS's New York and Geneva focus is complementary to the Commonwealth Secretariat's London-based work rather than competitive with it.

11. Conclusion

The Forum of Small States is, by any institutional measure, a success story of Singapore's foreign policy. Founded in 1992 as a modest New York coordination mechanism, it had grown by 2026 into a forum of over one hundred states spanning every UN regional group, addressing climate justice, trade reform, UN institutional governance, maritime security, and digital governance. It had remained operationally active for over three decades without a formal charter, a paid secretariat, or a binding institutional mandate — achievements of diplomatic maintenance that reflect consistent investment by Singapore's MFA and Permanent Missions.

The success of FOSS illustrates several principles of Singapore's small-state realism doctrine (see SG-M-19) in applied form. First, the power of institutional design: by choosing informality deliberately, FOSS's founders avoided the organisational pathologies that afflicted more ambitious multilateral experiments and created a platform that could grow rapidly without triggering membership-criteria disputes. Second, the value of the convenor position: Singapore's willingness to bear the administrative costs of running FOSS in exchange for the reputational and informational benefits of convening it reflects the logic that small states can convert structural disadvantage into strategic advantage through institutional investment. Third, the coalition-building logic that amplifies small-state voice: individually, any FOSS member is marginal in UN politics; collectively, their numbers make them a political force that major powers cannot ignore in Security Council elections, treaty ratifications, and General Assembly procedural decisions.

The structural challenges facing FOSS in 2026 are real. The erosion of the multilateral order — US-China rivalry fracturing WTO and WHO governance, Security Council paralysis on Ukraine and other crises, vaccine nationalism exposing the limits of global health solidarity — threatens the rules-based framework that FOSS exists to reinforce. The political diversification of FOSS's membership makes consensus increasingly difficult on the most contentious current issues. And Singapore's own changing position in the international system — increasingly wealthy, increasingly sophisticated, facing its own existential challenges from great-power competition — requires continuous recalibration of how it balances its national interests with its FOSS convenor responsibilities.

But the through-line is clear. Singapore founded FOSS because it understood, in 1992, that a small state's survival in an anarchic international system depends on the maintenance of rules that large states would otherwise be free to ignore. Three decades later, that understanding has not changed. What has changed is the scale of the threat to those rules and the breadth of the coalition — over one hundred states, more than half of all UN members — that Singapore has assembled to defend them.
