Section 1: Key Takeaways

• Singapore's foreign policy is the foreign policy of a state that was never supposed to exist independently. Expelled from Malaysia on 9 August 1965, a Chinese-majority city-state of 1.9 million people with no hinterland, no natural resources, and no army, Singapore had to construct from nothing a diplomatic architecture capable of securing its survival in one of the world's most strategically contested regions. That it has done so for over sixty years -- maintaining sovereignty, prosperity, and international standing -- is among the most improbable achievements in the history of post-colonial state-building.

• The foundational principles of Singapore's foreign policy were established in the first five years of independence and have never been abandoned: absolute sovereignty, non-alignment, adherence to international law, multilateralism through the United Nations, regional embedding through ASEAN, a balance-of-power approach to great-power relations, and the conviction that a small state's survival depends on a rules-based international order. These principles were articulated primarily by S. Rajaratnam, Singapore's first Foreign Minister (1965-1980), and reinforced by every subsequent holder of the office.

• The "poisonous shrimp" doctrine -- making Singapore so costly to swallow that no predator would attempt it -- was the conceptual bridge between foreign policy and defence policy. Over time, the metaphor evolved: by the 2000s, strategic thinkers preferred the "smart prawn" formulation, emphasising not merely deterrence but the capacity to be useful, relevant, and indispensable to the major powers, ensuring that they had a positive stake in Singapore's continued existence.

• ASEAN co-founding in 1967 was Singapore's most consequential early diplomatic decision. It embedded the new state in a regional framework that transformed Southeast Asia from a zone of confrontation to a zone of cooperation, committed larger neighbours to consultation and peaceful dispute settlement, and gave Singapore an institutional platform from which to project influence disproportionate to its size.

• The balance between the United States and China has been the central organising challenge of Singapore's great-power diplomacy since the end of the Cold War and has become acute since the 2010s. Singapore's position -- maintaining productive relationships with both while formally allying with neither, deepening defence cooperation with the United States while building deep economic ties with China -- requires constant calibration and has drawn criticism from both Washington and Beijing at different moments.

• Tommy Koh's presidency of the Third UN Conference on the Law of the Sea (UNCLOS, 1981-1982) remains Singapore's single greatest individual diplomatic achievement. It demonstrated that a small state could not merely participate in but actually lead the creation of global governance frameworks -- a proposition that has informed Singapore's approach to multilateral diplomacy ever since.

• Singapore's response to Russia's invasion of Ukraine in 2022 -- imposing autonomous sanctions outside the UN framework for the first time in its history -- was a watershed moment that demonstrated the country would pay real economic costs to defend the principle that large states cannot simply absorb smaller ones. This was not altruism but existential self-interest: the principle at stake was the same principle on which Singapore's own survival depends.

• The Ministry of Foreign Affairs, built from nothing in 1965, has been developed into one of the most professional diplomatic services in Asia. Singapore's diplomatic corps operates approximately 50 overseas missions, covering 192 countries. The deliberate investment in diplomatic talent -- through scholarships, training, and the cultivation of a cadre of intellectually formidable diplomats -- has been a core component of the small-state strategy.

• Economic diplomacy has been inseparable from political diplomacy. Singapore's 27 bilateral and regional free trade agreements, its membership in the CPTPP and RCEP, and its role as a global financial and trading hub are not merely economic instruments but strategic assets that create interdependencies with major powers, making Singapore's continued prosperity a shared interest.

• The Shangri-La Dialogue, hosted annually in Singapore since 2002 by the International Institute for Strategic Studies (IISS), has become Asia's premier defence diplomacy forum. Singapore's role as permanent host has reinforced its positioning as a neutral convening space for security dialogue -- a function that served Singapore well when it hosted the Trump-Kim summit in June 2018.

• The fundamental tension in Singapore's foreign policy has remained constant for sixty years: between the imperative to be principled (upholding sovereignty, international law, and the rules-based order) and the necessity of being pragmatic (maintaining relations with authoritarian regimes, accommodating great-power interests, and prioritising national survival over abstract values). Singapore's diplomatic self-presentation as "the principled pragmatist" is the resolution of this tension -- though critics argue it sometimes tilts too far toward pragmatism.

Section 2: Record in Brief

Singapore's foreign policy is best understood as a comprehensive survival strategy for a city-state that defies the normal logic of sovereign statehood. At 728 square kilometres, with a population that has grown from 1.9 million in 1965 to approximately 5.9 million in 2025, Singapore lacks every conventional attribute of national power except one: its strategic location at the southern tip of the Malay Peninsula, commanding the Strait of Malacca through which roughly a quarter of global trade passes. Everything else -- military deterrence, diplomatic networks, trade agreements, multilateral positioning, the cultivation of soft power and reputation -- has had to be constructed deliberately, maintained assiduously, and adapted continuously.

The architecture was built in three phases. In the first phase (1965-1975), the existential task was to secure international recognition, establish a diplomatic presence, join the United Nations and ASEAN, manage the fraught relationships with Malaysia and Indonesia, and build a foreign ministry and diplomatic service from scratch. S. Rajaratnam, a journalist with no diplomatic training, accomplished this with an intellectual clarity and strategic imagination that shaped Singapore's external posture for decades. The second phase (1975-1990) saw Singapore become a significant player in Cold War diplomacy -- leading ASEAN's response to the Vietnamese invasion of Cambodia, managing the regional implications of superpower competition, and beginning to build the dense network of trade agreements and security partnerships that would define the mature foreign policy. The third phase (1990-2026) encompasses the post-Cold War recalibration, the rise of China, the intensification of US-China rivalry, the proliferation of multilateral initiatives (FOSS, 3G, IPEF, RCEP, CPTPP), and the emergence of new diplomatic challenges including climate change, cyber governance, pandemic management, and the defence of the rules-based order against revisionist powers.

Across all three phases, five pillars have supported the architecture: sovereign independence (refusing subordination to any power), regional embedding through ASEAN, active multilateralism through the UN system and other institutions, a balance-of-power approach to great-power relations, and military deterrence through the Singapore Armed Forces and security partnerships including the Five Power Defence Arrangements. These pillars were erected in the first decade of independence and have been reinforced and adapted but never abandoned.

The policy domain of foreign affairs is distinctive within Singapore's governance model in one critical respect: it is the domain where the domestic and the external are most tightly fused. Singapore's multiracial compact at home -- the insistence on being a multiracial, multilingual, secular state rather than a Chinese city-state -- constrains and shapes every external relationship. The decision to recognise the People's Republic of China only after Indonesia had done so (1990), the refusal to be perceived as a Chinese proxy in Southeast Asia, the careful management of relations with the Islamic world, and the deliberate cultivation of Malay and Indian representation in foreign policy leadership roles are all expressions of this domestic-foreign policy nexus. Foreign policy is not conducted in a separate compartment from domestic governance; in Singapore, they are aspects of a single survival strategy.

Section 4: Background and Context

The Existential Geography

Singapore's foreign policy cannot be understood apart from its geography. The island sits at the southern tip of the Malay Peninsula, commanding the Strait of Malacca -- one of the world's most strategically important waterways. It is 728 square kilometres. Its nearest neighbours are Malaysia, to which it is connected by a causeway and a second link, and Indonesia, whose Riau Islands lie within sight of Singapore's southern shore. This geography produces three permanent conditions: strategic importance to every major maritime power, physical vulnerability to its immediate neighbours, and total dependence on trade and external supply for food, water, energy, and raw materials.

The ethnic arithmetic compounded the geographic vulnerability. At independence, Singapore was approximately 75 per cent Chinese, 14 per cent Malay, 8 per cent Indian, and 3 per cent other ethnicities. It was, and remains, the only Chinese-majority sovereign state outside of China and Taiwan. This fact has shaped every external relationship: Malaysia and Indonesia viewed Singapore with suspicion as a potential Chinese "third column"; China regarded it as a natural ally by ethnic affinity; and Singapore's own leaders understood that any perception of being a Chinese state in a Malay-Muslim region would be fatal to its security.

The Intellectual Foundations

The intellectual architecture of Singapore's foreign policy was built primarily by three minds: S. Rajaratnam provided the ideological framework -- sovereignty, non-alignment, international law, the moral imperative of a rules-based order; Lee Kuan Yew provided the strategic realism -- the cold assessment of power, the cultivation of great-power relationships, the refusal to be sentimental about alliances; and Goh Keng Swee, though primarily associated with economic and defence policy, contributed the institutional pragmatism -- the understanding that foreign policy required a professional ministry, a trained diplomatic corps, and intelligence capabilities.

These three perspectives were complementary rather than contradictory, and their synthesis produced the distinctive quality of Singapore's diplomatic posture: principled in rhetoric, pragmatic in practice, and relentlessly focused on the single overriding objective of national survival. Every subsequent Foreign Minister -- Suppiah Dhanabalan (1980-1988), Wong Kan Seng (1988-1994), S. Jayakumar (1994-2004), George Yeo (2004-2011), K Shanmugam (2008-2011), and Vivian Balakrishnan (2015-present) -- has operated within this framework while adapting it to changed circumstances.

The Post-Colonial Inheritance

Singapore inherited from the British colonial period several assets and several liabilities relevant to foreign policy. The assets included the English language as a working language of government and diplomacy, common-law legal institutions, the physical infrastructure of a major naval base, and relationships with the Commonwealth. The liabilities included unresolved boundary disputes, water dependency on Malaysia (formalised in agreements of 1961 and 1962), and the legacy of Konfrontasi -- Indonesia's campaign of low-level military confrontation against the formation of Malaysia, which had included bombings on Singapore soil.

The British withdrawal East of Suez, announced in 1967 and completed in 1971, removed the security umbrella that had existed since the founding of modern Singapore in 1819. The withdrawal was economically traumatic -- the British military presence had accounted for roughly 20 per cent of GDP and employed tens of thousands -- and strategically alarming. It forced Singapore to build an indigenous defence capability from scratch, a project that shaped foreign policy by making military deterrence a core complement to diplomacy.

The MFA: Building a Diplomatic Service from Nothing

When Singapore became independent, it had no foreign ministry, no diplomatic corps, and no institutional capacity for conducting foreign relations. Rajaratnam had to build everything simultaneously: recruiting and training officers, establishing overseas missions, developing policy capacity, and managing crises that would not wait for the institution to mature.

The early MFA was staffed by officers borrowed from other ministries, seconded military personnel, and a handful of recruits identified through the government scholarship system. The first generation of Singapore diplomats were generalists by necessity -- there was no specialised diplomatic training programme, and many learned on the job. What they lacked in formal training, they compensated for with intellectual ability, languages (many were multilingual), and the intensity of commitment that comes from representing a country whose survival is in question.

By the 1980s, the MFA had developed into a professional service with established career tracks, specialised desks (ASEAN, UN, bilateral), and a cadre of experienced officers. The foreign service scholarship, modelled on the broader government scholarship system, became a key talent pipeline. The Ministry of Foreign Affairs building at Tanglin, opened in 2005, symbolised the institution's maturation.

As of 2025, the MFA is organised into functional and geographic directorates. Key divisions include the ASEAN Directorate, the International Organisations Directorate (covering the UN system, FOSS, and 3G), the Policy Planning Directorate, the Technical Cooperation Directorate (which manages development assistance and capacity-building programmes), and geographic desks covering Northeast Asia, South Asia, the Americas, Europe, the Middle East, and Africa. The Permanent Secretary for Foreign Affairs heads the administrative apparatus; the Minister for Foreign Affairs sets political direction. The position of Ambassador-at-Large, held by figures including Tommy Koh, Bilahari Kausikan, and Chan Heng Chee, allows senior diplomats to continue contributing beyond normal retirement.

Section 5: The Primary Record

Phase I: Founding the Framework (1965-1975)

Securing International Recognition

The most urgent diplomatic task in August 1965 was to secure international recognition of Singapore's sovereignty. Rajaratnam moved with extraordinary speed. Singapore was admitted to the United Nations on 21 September 1965, barely six weeks after independence. It joined the Commonwealth, the Non-Aligned Movement, and a range of international organisations in rapid succession. Each admission was a brick in the wall of legitimacy: every international body that accepted Singapore made its existence more difficult to reverse.

Rajaratnam's maiden speech to the UN General Assembly established the philosophical anchor of Singapore's multilateral diplomacy. He declared that Singapore would pursue a policy of non-alignment, friendship with all nations, and adherence to the principles of the UN Charter. He emphasised that small states had a particular stake in the international rule of law because they lacked the military power to defend themselves against larger neighbours unilaterally. This was not idealism but strategic calculation: a rules-based order was the environment in which Singapore could exist; a power-based order was one in which it would be absorbed.

The Poisonous Shrimp and the Smart Prawn

The metaphor most associated with Singapore's early strategic thinking is the "poisonous shrimp." Attributed variously to Lee Kuan Yew and Rajaratnam, the doctrine held that Singapore was too small to be a meaningful military power, but it could make itself so costly to conquer that no rational adversary would attempt it. The shrimp cannot defeat the fish, but if it is poisonous, the fish will leave it alone.

This doctrine bridged foreign policy and defence policy. It justified the creation of a conscript army through National Service (introduced in 1967), the development of a technologically sophisticated armed forces, and the pursuit of security partnerships that would raise the cost of any attack on Singapore. It also informed the diplomatic posture: Singapore would be firm in asserting its sovereignty precisely because firmness was the only thing that prevented larger powers from treating it as dispensable.

The doctrine evolved significantly over the decades. By the 1980s, Singapore's strategic thinkers had moved beyond the "poisonous shrimp" to what some called the "porcupine" model -- not merely poisonous but visibly armed, deterring through the certainty of immediate pain. By the 2000s, a further evolution produced the "smart prawn" metaphor, attributed to various commentators and officials. The smart prawn does not merely deter predators; it makes itself useful to the larger fish. It provides services, intelligence, and connectivity. It ensures that the major powers have a positive stake in its survival -- not out of affection but out of self-interest. This evolution from passive deterrence to active relevance captures the maturation of Singapore's foreign policy from survival to strategy.

ASEAN: The Regional Anchor

The decision to co-found ASEAN on 8 August 1967 was Singapore's most consequential early diplomatic act. For Singapore, the strategic calculation was multilayered. First, ASEAN embedded Singapore in a regional framework that normalised its existence -- a Singapore that was a member of a regional organisation was harder to dismiss as an anomaly. Second, ASEAN's foundational principles -- respect for sovereignty, non-interference in internal affairs, peaceful settlement of disputes -- were precisely the principles that served Singapore's interests as the smallest member. Third, ASEAN provided a framework for managing the relationships with Indonesia and Malaysia, which had only recently emerged from Konfrontasi and the trauma of separation.

Rajaratnam insisted that ASEAN must operate on the basis of sovereign equality -- that Singapore's voice would count equally with Indonesia's despite the vast disparity in size and population. This principle, embedded in ASEAN's consensus-based decision-making, has been both Singapore's greatest protection within the organisation and, at times, its greatest frustration.

Singapore's role within ASEAN has evolved from grateful participant to active shaper. Singapore pushed for ASEAN economic integration through the ASEAN Free Trade Area (AFTA, 1992), championed the ASEAN Regional Forum (ARF, 1994) and the East Asia Summit (EAS, 2005), promoted the ASEAN Charter (signed 2007), and supported the ASEAN Economic Community (AEC, 2015). When Singapore chaired ASEAN in 2018, it used the platform to advance the ASEAN Smart Cities Network, digital economy integration, and the promotion of ASEAN centrality in regional architecture.

The Five Power Defence Arrangements

When Britain withdrew its military forces, the FPDA established in 1971 among the UK, Australia, New Zealand, Malaysia, and Singapore provided a residual security commitment during the vulnerable early years of SAF development. The FPDA was consultative rather than binding -- it committed the parties to consult, not to fight -- but it signalled to potential adversaries that Singapore was not alone. The FPDA has been maintained for over fifty years and, as of 2026, continues to conduct annual integrated exercises.

Phase II: Cold War Diplomacy and Expansion (1975-1990)

The Cambodia Diplomacy

Singapore's most prominent Cold War diplomatic engagement was its role in the Cambodian crisis following Vietnam's invasion in December 1978. Singapore, under Rajaratnam and subsequently Dhanabalan, led ASEAN's campaign to deny the Vietnamese-installed government international recognition and to insist on Vietnam's withdrawal. The principled case was clear: if the international community accepted that a large state could invade a small state for any reason, however sympathetic, then no small state was safe. The moral complexity was equally clear: the Khmer Rouge had committed genocide, and Vietnam's invasion had ended it.

Singapore's diplomats, working through ASEAN and the UN, maintained the Cambodian seat at the United Nations for a coalition that included the Khmer Rouge -- a position that drew sustained moral criticism. The Cambodian issue was resolved through the Paris Peace Agreements of 1991. The episode demonstrated both the strengths and costs of Singapore's approach: the sovereignty principle was upheld, but the moral ambiguities were real.

Tommy Koh and UNCLOS

Tommy Koh's presidency of the Third UN Conference on the Law of the Sea (1981-1982) was Singapore's greatest individual diplomatic achievement. Koh presided over the final and most complex phase of negotiations that produced the United Nations Convention on the Law of the Sea, adopted on 30 April 1982 by a vote of 130–4–17 and opened for signature on 10 December 1982 at Montego Bay. For Singapore, the stakes were enormous: as a maritime trading state whose existence depended on freedom of navigation, any legal regime governing the oceans was a matter of survival.

Koh navigated negotiations involving over 160 countries with fundamentally different interests. He developed the "package deal" approach, in which no single issue was settled until all issues were settled, preventing powerful states from cherry-picking favourable provisions. UNCLOS has been described as the "constitution of the oceans" and is one of the most comprehensive international agreements ever negotiated. For Singapore, it demonstrated that a small state could shape global governance -- a demonstration that continues to inspire Singapore's approach to multilateral engagement.

Establishing the US Security Relationship

The 1988 Memorandum of Understanding on military access formalised what had been developing for years: a deep security relationship with the United States that fell short of a formal alliance but provided substance equivalent to one. The MOU, updated in 2005 and 2019, provided US naval and air forces with access to Singapore's military facilities. This was a strategic choice of the first order: by providing the United States with a foothold in Southeast Asia after the closure of bases in the Philippines (1991-1992), Singapore ensured that American power remained present in the region -- a presence that Singapore's leaders viewed as essential to the regional balance of power.

The relationship was carefully constructed to avoid the appearance of subservience. There was no status of forces agreement, no formal alliance treaty, and no permanent basing. Singapore maintained its non-aligned posture while practically integrating with the US security architecture to a degree that few formally allied states matched.

Phase III: Post-Cold War Recalibration (1990-2010)

Recognising China

Singapore's establishment of formal diplomatic relations with the PRC in October 1990 -- the last ASEAN state to do so -- was the culmination of decades of deliberate strategic sequencing. Lee Kuan Yew had insisted that Singapore could not recognise China before Indonesia did, as this would confirm the suspicion that Singapore was a Chinese stalking horse in Southeast Asia. The delay was not hostility toward Beijing but diplomatic self-preservation.

Once relations were established, they deepened rapidly. The Suzhou Industrial Park (1994), the Sino-Singapore Tianjin Eco-City (2008), and the Chongqing Connectivity Initiative (2015) were government-to-government projects that transferred Singapore's development model to Chinese contexts. China became Singapore's largest trading partner. Singapore became a major hub for RMB internationalisation and Chinese outward investment. Yet the relationship remained structurally complicated by Singapore's unofficial but substantive relationship with Taiwan, including SAF training facilities on the island, and by periodic tensions over the South China Sea.

Institutional Innovation: FOSS and 3G

The Forum of Small States (FOSS), established at Singapore's initiative in 1992, brought together UN member states with populations under 10 million to coordinate positions on issues of common concern. By the 2020s, FOSS had grown to over 100 members and had become a significant platform for small-state advocacy on climate change, digital governance, and institutional reform.

The Global Governance Group (3G), co-founded by Singapore in 2009, was a response to the proliferation of exclusive groupings -- the G7, the G20 -- that made decisions affecting all countries without small-state participation. The 3G advocated for G20 accountability, transparency, and small-state inclusion. Both FOSS and 3G represented Singapore's approach to multilateral diplomacy: if the existing architecture does not serve small-state interests, build new institutional mechanisms rather than accept exclusion.

Trade Agreements and Economic Diplomacy

Singapore's approach to trade agreements has been the most tangible expression of the fusion between economic and foreign policy. The Singapore-US Free Trade Agreement (2003), the first such agreement between the United States and an Asian country, was as much a strategic instrument as an economic one -- it deepened bilateral ties, created institutional linkages, and signalled American engagement in Southeast Asia. The Comprehensive Economic Cooperation Agreement (CECA) with India (2005) served a similar strategic function, diversifying Singapore's great-power relationships beyond the US-China axis.

By 2025, Singapore had signed 27 bilateral and regional free trade agreements, covering virtually all major trading partners. It was a founding member of both the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the Regional Comprehensive Economic Partnership (RCEP) -- the former a high-standards agreement linked to the US strategic orbit, the latter a China-inclusive agreement covering the world's largest trading bloc. Membership in both simultaneously was itself a statement of Singapore's balance-of-power position.

Total trade as a percentage of GDP consistently exceeds 300 per cent -- among the highest in the world. This extreme trade openness is not merely an economic characteristic; it is a strategic condition. It means that Singapore's prosperity depends on the stability of the global trading system, making the defence of free trade and open markets a foreign policy imperative equivalent to the defence of sovereignty.

Phase IV: The US-China Century and New Challenges (2010-2026)

Managing the US-China Rivalry

The defining strategic challenge of the current era has been the intensification of US-China rivalry and the pressure it places on Singapore's balance-of-power strategy. Singapore's consistent position, articulated by PM Lee Hsien Loong, Foreign Minister Vivian Balakrishnan, and senior diplomats including Bilahari Kausikan, has been that Singapore does not wish to and will not choose sides.

Lee Hsien Loong's keynote speech at the Shangri-La Dialogue in May 2019, titled "The Endangered Asian Century," was the most comprehensive public articulation of this position. He argued that Asia needed an inclusive framework that could accommodate both the United States and China, that forcing countries to choose between the two was destructive, and that ASEAN had a role to play in maintaining space for countries that wished to maintain productive relationships with both great powers.

The Terrex incident of 2016-2017 -- when nine SAF armoured personnel carriers were detained at Hong Kong following Singapore's expressions of support for the international tribunal ruling against China's South China Sea claims -- illustrated the pressures. Singapore responded with quiet diplomacy and public firmness, refusing to abandon its positions on international law or its military relationship with Taiwan. The vehicles were returned, relations were repaired, but the episode demonstrated that balance-of-power diplomacy carried real costs.

Singapore has participated selectively in US-aligned initiatives: joining the Indo-Pacific Economic Framework (IPEF) while maintaining distance from overtly military-focused groupings like AUKUS. It has deepened defence cooperation with the United States -- including rotational deployment of US Littoral Combat Ships since 2013 and expanded joint exercises -- while simultaneously building economic interdependence with China and engaging Beijing through the Belt and Road Initiative.

Singapore as Mediator and Neutral Venue

Singapore's positioning as a trusted neutral venue for high-stakes diplomacy reached its apogee with the Trump-Kim summit of 12 June 2018 -- the first-ever meeting between a sitting US President and a North Korean leader. Singapore was chosen because it maintained diplomatic relations with both countries, possessed the security infrastructure to manage the event, and was trusted by both sides not to embarrass either. The logistics were formidable; the diplomatic symbolism was significant. Singapore bore the estimated S$20 million cost as an investment in its reputation as a neutral convening space.

This role is not accidental but cultivated. The Shangri-La Dialogue, hosted annually at the Shangri-La Hotel since 2002, has become Asia's most important defence diplomacy forum. Organised by the International Institute for Strategic Studies (IISS) with the Singapore government's active support, the Dialogue brings together defence ministers, military chiefs, and strategic thinkers from across the Asia-Pacific and beyond. It provides a platform for signalling, side-meetings, and the kind of informal exchanges that formal diplomatic channels cannot accommodate. Singapore's role as permanent host reinforces its positioning as the region's diplomatic crossroads.

The IISS presence in Asia, anchored by the Shangri-La Dialogue and the IISS-Asia office established in Singapore, has enhanced Singapore's status as a hub for strategic analysis and policy dialogue. This is consistent with the broader strategy of making Singapore indispensable to the infrastructure of regional order -- the smart prawn in its most refined form.

The Russia-Ukraine Watershed (2022)

Singapore's response to Russia's invasion of Ukraine in February 2022 was the most consequential foreign policy decision since the imposition of the ASEAN diplomatic framework on the Cambodian crisis. On 28 February 2022, Foreign Minister Vivian Balakrishnan announced that Singapore would impose sanctions on Russia -- including export controls on items that could be used as weapons, restrictions on certain Russian banks, and prohibitions on transactions related to the Russian central bank.

This was unprecedented. Singapore had never imposed unilateral sanctions outside the UN Security Council framework. The decision was explicitly grounded in the existential principle: Balakrishnan told Parliament that "a world order in which a large country can simply invade and annex a smaller neighbour is a world order in which Singapore cannot exist." PM Lee reinforced: "Russia's invasion of Ukraine is a serious violation of international law and of the UN Charter. Singapore must condemn such acts of aggression. As a small state, this is an existential issue for us."

The sanctions were carefully calibrated -- significant enough to be meaningful but not so broad as to sever all ties with Moscow. Singapore maintained diplomatic relations with Russia. The decision drew criticism from some business interests and from observers who noted the selectivity of Singapore's application of the sovereignty principle. The government's response was that the Ukraine invasion was a clear-cut case of territorial conquest -- precisely the scenario that most directly threatened Singapore's own existence.

Defence Diplomacy

Defence diplomacy has been a growing dimension of Singapore's foreign policy, reflecting the understanding that military relationships create channels of communication and trust that complement civilian diplomacy. The SAF conducts regular bilateral exercises with the United States, Australia, India, France, the United Kingdom, and numerous other countries. Singapore's defence spending, maintained at approximately 3 per cent of GDP -- higher than the NATO benchmark of 2 per cent -- reflects the continued centrality of deterrence to the foreign policy framework.

The FPDA has been periodically updated and expanded, with increasingly complex integrated exercises. Bilateral defence cooperation agreements with India, France, and other countries have broadened the network. Singapore's arms procurement -- from the United States (F-16s, F-35s on order), France, Germany, Sweden, and Israel -- has been managed to avoid excessive dependence on any single supplier while building interoperability with key partners.

Singapore's hosting of foreign military training -- including the provision of training areas in other countries for the SAF (Australia, Brunei, France, the United States, and historically Taiwan) -- creates reciprocal relationships that extend Singapore's strategic depth far beyond its 728 square kilometres.

Climate Diplomacy

Climate diplomacy has emerged as a significant dimension of Singapore's foreign policy since the 2010s. As a low-lying island state, Singapore faces direct existential risk from sea-level rise -- an estimated S$100 billion long-term investment in coastal protection has been signalled. Yet as a petrochemical refining hub and a city-state with high per capita carbon emissions, Singapore also faces pressure to decarbonise.

Singapore's climate diplomacy has been characterised by the same principled pragmatism that marks its broader foreign policy. It introduced a carbon tax in 2019 -- the first in Southeast Asia -- and raised it significantly in 2024. It has positioned itself as a hub for carbon trading and green finance. At international climate negotiations, Singapore has balanced solidarity with small island developing states (which share its vulnerability to sea-level rise) with defence of its economic interests as a fossil fuel-dependent trading hub. The government's framing -- that Singapore will do its part but cannot be expected to bear costs disproportionate to its contribution to global emissions -- mirrors the broader foreign policy logic of principled pragmatism constrained by survival imperatives.

Soft Power and Reputation Management

Singapore's cultivation of its international reputation has been deliberate and sustained. The country consistently ranks among the world's most globalised economies (KOF Globalisation Index), the most efficient ports, the most connected air hubs, and the most business-friendly regulatory environments. These rankings are not merely economic indicators; they are components of a soft power strategy that makes Singapore's continued prosperity a shared interest of the global business and policy community.

The Singapore Cooperation Programme (SCP), established in 1992, provides technical assistance and training to developing countries -- a form of development diplomacy that builds goodwill and influence. Singapore has trained thousands of officials from across Asia, Africa, and the Pacific in public administration, urban planning, water management, and governance. This capacity-building programme serves both altruistic and strategic purposes: it creates networks of influence, demonstrates Singapore's development model, and generates goodwill that translates into diplomatic support at the UN and other forums.

Section 6: Key Figures

S. Rajaratnam (1915-2006)

Foreign Minister (1965-1980), Second Deputy Prime Minister (1980-1985). A Sri Lankan Tamil journalist who became one of the PAP's founding members and its chief ideologist. Rajaratnam built Singapore's foreign policy architecture from nothing: the commitment to non-alignment, the emphasis on international law, the strategy of embedding Singapore in multilateral institutions. He co-founded ASEAN, drafted the National Pledge, and led ASEAN's response to the Vietnamese invasion of Cambodia. His intellectual clarity and moral conviction set the standard for Singapore's diplomatic self-presentation.

Lee Kuan Yew (1923-2015)

Prime Minister (1959-1990), Senior Minister (1990-2004), Minister Mentor (2004-2011). While Rajaratnam built the institutional architecture, Lee conducted the personal diplomacy that secured Singapore's great-power relationships. His relationships with world leaders -- from Deng Xiaoping to Margaret Thatcher to George H.W. Bush -- gave Singapore access and influence far beyond its size. His strategic assessments, particularly on China's rise and the US role in Asia, were sought by foreign leaders well into his retirement. Lee's foreign policy contribution was indivisible from his domestic leadership: the credibility of Singapore's diplomacy rested on the credibility of its governance.

Tommy Koh (b. 1937)

Ambassador-at-Large. Singapore's most decorated diplomat. Koh's presidency of the Third UN Conference on the Law of the Sea produced Singapore's greatest individual diplomatic achievement. He subsequently served as Ambassador to the United States (1984-1990), chaired the preparatory committee for the 1992 Earth Summit in Rio, and became Singapore's chief negotiator on numerous multilateral issues. Koh embodied the proposition that small states can shape international law through diplomatic excellence.

Suppiah Dhanabalan (b. 1937)

Foreign Minister (1980-1988). A Ceylonese Tamil who succeeded Rajaratnam and managed the Cambodia diplomacy during its most complex phase. Dhanabalan maintained the principled approach to sovereignty while navigating intense moral criticism. His subsequent departure from politics -- he resigned as a minister in 1993 citing personal reasons, though his disagreement with the 1987 ISA detentions was later disclosed -- added complexity to his legacy.

S. Jayakumar (b. 1939)

Foreign Minister (1994-2004), Senior Minister (2009-2011). A law professor who brought legal rigour to foreign policy. Jayakumar managed Singapore's case before the International Court of Justice on the Pedra Branca sovereignty dispute and oversaw the expansion of Singapore's FTA network. His memoir Diplomacy: A Singapore Experience (2011) is one of the most revealing insider accounts of Singapore's foreign policy decision-making.

Chan Heng Chee (b. 1942)

Ambassador to the United States (1996-2012) -- the longest-serving ambassador to Washington from any country during that period. An academic political scientist who built the Singapore-US relationship into its mature form, managing it through multiple administrations. She was instrumental in negotiating the US-Singapore FTA.

George Yeo (b. 1954)

Foreign Minister (2004-2011). A former brigadier-general who brought a distinctive intellectual style, emphasising civilisational dialogue, ASEAN community-building, and engagement with China. He championed the ASEAN Charter (signed 2007) and managed the relationship with China during rapid economic interdependence growth. Lost his parliamentary seat in the 2011 general election.

Bilahari Kausikan (b. 1954)

Second Permanent Secretary for Foreign Affairs, subsequently Ambassador-at-Large. Arguably the most intellectually influential figure in Singapore's foreign policy establishment after Rajaratnam. His essays and speeches have articulated the realist foundations of Singapore's foreign policy with exceptional clarity. His 1993 Vienna speech on Asian contextualism of human rights was controversial but influential. His writings on US-China rivalry and on the psychology of small-state diplomacy constitute an essential body of strategic thought.

K Shanmugam (b. 1959)

Foreign Minister (2008-2011), subsequently Minister for Home Affairs and Minister for Law. Brought a lawyer's precision to foreign policy discourse. His parliamentary speeches on international law and sovereignty are among the most analytically rigorous statements of Singapore's foreign policy principles.

Vivian Balakrishnan (b. 1961)

Foreign Minister from 2015. A former ophthalmologist who managed Singapore's foreign policy during the most challenging period of US-China competition, navigated COVID-19's impact on international relations, oversaw the Trump-Kim summit logistics, and led Singapore's response to the Russia-Ukraine crisis. His parliamentary statement on the Ukraine sanctions was widely cited internationally as a model of principled small-state foreign policy.

Kishore Mahbubani (b. 1948)

Permanent Representative to the United Nations (1984-1989, 1998-2004), subsequently Dean of the Lee Kuan Yew School of Public Policy. Became one of the most prominent international voices arguing for rebalancing global governance. His books -- Can Asians Think? (1998), Has China Won? (2020) -- provoked debate about Western assumptions. His relationship with the Singapore government became more complex as his advocacy for accommodation with China sometimes sat uneasily with official positions.

Section 7: Stories and Anecdotes

Rajaratnam's First Day at the UN (1965)

When Rajaratnam rose to speak at the United Nations General Assembly in September 1965, Singapore had been an independent country for barely six weeks. The delegation was tiny. Singapore had no diplomatic infrastructure, no established relationships, and very little international visibility. Rajaratnam spoke with the conviction of a man who understood that words were, for the moment, Singapore's only weapon. He told the Assembly that Singapore "desired to be friends with all countries" and pledged commitment to the principles of the Charter. The speech was modest in length but foundational in consequence. As one diplomat later recounted, many delegations had not heard of Singapore; several confused it with other newly independent states. Rajaratnam's task was not merely to state a position but to establish that Singapore existed and intended to remain in existence.

Lee Kuan Yew and the Water Tap

Lee Kuan Yew frequently told the story that shortly after separation in 1965, a Malaysian politician had warned that if Singapore did not behave, Malaysia would "cut off the water" -- a threat that Lee said he took with deadly seriousness. "Every other policy has its priority, but water comes before everything else," he told associates. The threat drove Singapore's decades-long investment in NEWater, desalination, and reservoir expansion. It also became a parable within the MFA: dependency on any single external source for any critical resource was a strategic vulnerability that foreign policy must work to eliminate.

The S$20 Million Handshake

When Singapore was selected as the venue for the 2018 Trump-Kim summit, the government made the strategic decision to bear the entire cost -- estimated at S$20 million for security, logistics, and the closure of the Sentosa Island venue. Asked whether this was an appropriate use of public funds, PM Lee Hsien Loong responded that it was an investment in Singapore's reputation as a neutral venue for high-stakes diplomacy -- a reputation worth far more than the cost. The Ministry of Foreign Affairs had worked with extraordinary speed to organise the logistics, with officers reportedly sleeping in the office for days. When the summit produced a handshake photograph seen by billions, Foreign Minister Balakrishnan later reflected that "no advertising budget could have bought that kind of global visibility."

Tommy Koh's Marathon Night

The final session of the UNCLOS conference in 1982, which Koh chaired, lasted through the night. Over 160 delegations had to reach agreement on a text of extraordinary complexity. Koh later recalled that the key to success was patience and the recognition that every delegation, however small, had legitimate interests. "You cannot bully countries into agreeing," he said. "You have to persuade them that the outcome serves their interests." When the convention was finally adopted, several delegates reportedly wept. Koh's personal diplomacy became a model for Singapore's subsequent approach to multilateral negotiations: meticulous preparation, genuine respect for all parties, and the intellectual discipline to find formulations that accommodated competing interests without sacrificing core principles.

The "Poisonous Shrimp" Dinner

The evolution of Singapore's strategic metaphors has its own folklore. At a dinner in the early 2000s, a younger Singapore diplomat reportedly told a senior colleague that the "poisonous shrimp" metaphor was outdated. "We don't want to be poisonous," the younger diplomat argued. "We want to be the prawn that the fish cannot do without -- the prawn that cleans the teeth of the bigger fish, that provides a useful service. If we are useful, they will protect us." The senior diplomat reportedly considered this and responded: "Fine. But never forget that the prawn must also be able to sting. Usefulness without deterrence is just a menu item." The exchange, whether apocryphal or not, captures the transition from the "poisonous shrimp" to the "smart prawn" doctrine -- from survival through fear to survival through indispensability.

Bilahari at Vienna (1993)

At the 1993 Vienna World Conference on Human Rights, Bilahari Kausikan delivered a speech that provoked a fierce reaction from Western delegations. He argued that Asian states had legitimate grounds for contextualising human rights within their own cultural and developmental frameworks -- a position that Western human rights advocates condemned as providing cover for authoritarianism. After the speech, an American diplomat reportedly approached Kausikan and said, "That was the most dangerous speech I've heard at this conference." Kausikan's response, as he later recounted it: "Good. It was meant to be taken seriously." The Vienna speech positioned Singapore as a leading voice in the Asian values debate of the 1990s and established Kausikan's reputation as one of the most intellectually formidable -- and deliberately provocative -- diplomats in Asia.

Section 8: Arguments and Rhetoric

Logos: The Small-State Structural Argument

The foundational logical argument of Singapore's foreign policy is structural: small states cannot survive in an international system governed by power alone. This argument has been articulated with remarkable consistency across sixty years.

Rajaratnam (1965): "We believe that the United Nations can play a significant role in maintaining peace and security... Small nations like Singapore depend on the existence of an international order that respects the sovereignty and territorial integrity of all states, large and small."

Bilahari Kausikan (2016): "The fundamental challenge for Singapore's foreign policy is to create the widest possible space for ourselves as a small country in an anarchic international system where the strong do what they can and the weak suffer what they must -- and to try to expand that space by promoting a rules-based international order."

K Shanmugam (2011): "We are not idealists. We do not believe that all countries will always behave well. But we believe that international law and institutions -- imperfect as they are -- are the best framework available for protecting the interests of small states. The alternative is the law of the jungle, and in the jungle, the small animal does not survive."

Pathos: The Existential Narrative

Singapore's foreign policy rhetoric is saturated with existential language. The country's leaders have consistently framed foreign policy choices not as preferences but as survival imperatives.

Lee Kuan Yew (1966): "We are a heart without a body... If we do not build our defences and our diplomacy with the utmost seriousness, we will not survive."

Lee Kuan Yew (various): "We are a small country. We cannot change the world. But we can make ourselves relevant to the major powers, so that they have an interest in our continued existence and prosperity."

Vivian Balakrishnan (2022, on Ukraine sanctions): "This is an existential issue for us. A world order in which a large country can simply invade and annex a smaller neighbour is a world order in which Singapore cannot exist."

Ethos: The Principled Pragmatist

Singapore's diplomatic self-presentation combines principled commitment to international law with unflinching pragmatism about power realities. The rhetorical persona is the principled pragmatist: a country that upholds rules because it benefits from them, not because it is naive about how the world works. This ethos requires credibility on both dimensions -- the willingness to bear costs for principles (Ukraine sanctions) and the willingness to make unsentimental choices (maintaining relations with authoritarian regimes).

Lee Hsien Loong (2019, Shangri-La Dialogue): "Countries large and small, must recommit themselves to working together on the basis of international law and agreed norms... But we must also be realistic about the changes taking place in the world, and work constructively to adapt the international order to new realities."

The rhetorical consistency across six decades is itself a diplomatic asset. When Singapore speaks on sovereignty, international law, or the rights of small states, it speaks with the authority of a country that has maintained the same position for sixty years. This consistency -- which critics sometimes call rigidity -- is a form of credibility capital that Singapore's diplomats deliberately cultivate and spend sparingly.

Section 9: The Contested Record

The Cambodia Controversy

Singapore's role in the Cambodian diplomacy of the 1980s remains the most contested episode in its foreign policy history. The principled case -- that accepting Vietnam's invasion would have established a dangerous precedent for small-state sovereignty -- is logically coherent and has been vindicated by the subsequent emphasis on sovereignty principles in Singapore's Ukraine response. The moral case against -- that Singapore effectively supported maintaining the Khmer Rouge's UN seat while the regime's victims remained unacknowledged -- is also compelling. Scholars remain divided. Singapore's position was internally consistent but externally costly in reputational terms, and the willingness to bear that cost itself became part of the foreign policy mythology: the small state that would pay a moral price to defend a principle on which its own survival depended.

The US-China Balance: Genuine Neutrality or Disguised Alignment?

The most persistent criticism of Singapore's foreign policy is that its professed neutrality between the United States and China masks a de facto strategic alignment with Washington. Critics point to the extensive US military access to Singapore's facilities, the depth of intelligence cooperation, Singapore's participation in US-aligned initiatives like IPEF, and the contrast between its outspoken criticism of Russia's Ukraine invasion and its more muted response to other large-power military actions. Singapore's leaders reject this characterisation, noting deep economic ties with China, resistance to joining explicitly anti-China groupings, and public criticism of US policies when warranted. The reality is almost certainly more nuanced than either position allows: Singapore's relationship with the United States is deeper in military and intelligence terms, while its economic interdependence with China is greater and growing. The balance is not symmetrical, but neither is it alignment.

Relations with Authoritarian Regimes

Singapore's pragmatic engagement with authoritarian governments -- from Myanmar's military junta to various Middle Eastern monarchies -- has drawn criticism from human rights organisations and Western commentators. Singapore's consistent response has been that it does not condition diplomatic relations on domestic governance models and that engagement is more likely to produce positive change than isolation. Critics counter that this conveniently aligns with commercial interests and that Singapore is selective in applying the sovereignty principle. The Myanmar case is particularly acute: Singapore is Myanmar's largest foreign investor and trading partner within ASEAN, and its response to the 2021 military coup was cautious, emphasising ASEAN consensus over condemnation -- a position that drew criticism from democracy advocates.

The CECA Controversy and Domestic-Foreign Policy Tensions

The Comprehensive Economic Cooperation Agreement with India became domestically controversial in the late 2010s and early 2020s, as public concern grew over Indian professionals entering Singapore on employment passes. Critics argued that CECA facilitated displacement of Singaporean professionals, particularly in IT and financial services. The government repeatedly clarified that CECA did not provide for free movement of labour, but the issue became entangled with broader anxieties about immigration, job competition, and ethnic composition. The episode revealed a structural gap between foreign policy elites and public sentiment -- a gap that may become more politically significant as Singapore's electoral environment becomes more competitive.

The "Asian Values" Debate

In the 1990s, Singapore was closely associated with the "Asian values" argument -- that East Asian societies had legitimate grounds for governance models different from Western liberal democracy. Kishore Mahbubani and Bilahari Kausikan were prominent advocates. Western critics accused Singapore of using cultural relativism to justify authoritarianism. The debate has faded but resurfaces whenever Singapore's domestic governance is scrutinised internationally. The foreign policy dimension is significant: the Asian values argument was not merely an academic exercise but a diplomatic strategy to resist Western pressure on domestic political arrangements while maintaining productive economic relationships with the West.

Selectivity in Applying the Sovereignty Principle

The Ukraine sanctions decision sharpened an existing criticism: that Singapore applies the sovereignty principle selectively. Singapore condemned and sanctioned Russia for invading Ukraine but did not impose similar sanctions following the US invasion of Iraq (2003), Saudi Arabia's intervention in Yemen (2015), or Israel's military operations in Gaza (2023-2024). Singapore's defence has been that the Ukraine case was a uniquely clear-cut instance of one sovereign state attempting to annex another -- distinguishable from other military interventions on legal and factual grounds. Critics argue this distinction is more convenient than principled.

Section 10: Outcomes and Evidence

Diplomatic Network

As of 2025, Singapore maintains diplomatic relations with 192 countries and operates approximately 50 overseas missions. For a country of 5.9 million people, this is an extraordinarily dense diplomatic network -- denser, proportionally, than most major powers.

Trade Architecture

Singapore has signed 27 bilateral and regional free trade agreements. It is simultaneously a member of both the CPTPP and RCEP. Total trade exceeds 300 per cent of GDP. Singapore is consistently ranked among the world's most open and connected economies. This trade architecture is the economic manifestation of the foreign policy strategy: it creates interdependencies with all major powers and embeds Singapore in the infrastructure of global commerce.

Security Partnerships

The SAF conducts regular bilateral exercises with the United States, Australia, India, France, the United Kingdom, and numerous other countries. The FPDA continues annual integrated exercises after more than fifty years. US Littoral Combat Ships have been rotationally deployed to Singapore since 2013. Defence spending at approximately 3 per cent of GDP reflects the continued centrality of deterrence. Singapore's F-35 acquisition programme, announced in 2020, signals continued investment in high-end military capability.

Multilateral Positions

Singapore has served on the UN Security Council (2001-2002), has held leadership positions in numerous UN bodies, and has been a consistent advocate for small-state representation. FOSS has grown from approximately 25 members to over 100. The 3G has become a recognised voice in global governance discussions.

International Rankings and Reputation

Singapore consistently ranks among the world's most globalised economies (KOF Index), the most efficient ports (PSA handles approximately one-fifth of global container transshipment), the most connected air hubs (Changi Airport consistently ranked among the world's best), and the most business-friendly regulatory environments (World Bank Doing Business rankings, prior to their discontinuation). These rankings reflect the success of a strategy that treats economic connectivity as national security.

Conflict Avoidance

Perhaps the most significant outcome is a negative one: Singapore has not been involved in any armed conflict since independence. In a region that has experienced wars, insurgencies, coups, and border conflicts, Singapore has maintained its security through a combination of deterrence, diplomacy, and strategic positioning. This is the ultimate test of a foreign policy, and by this measure, Singapore's has been extraordinarily successful.

Hosting Record

Singapore's hosting of the Shangri-La Dialogue (annually since 2002), the Trump-Kim summit (2018), various ASEAN summits, and numerous international conferences has established it as the region's premier venue for diplomatic engagement. This hosting capacity is itself a foreign policy asset -- it reinforces Singapore's centrality to regional order and generates reputational returns that exceed the financial costs.

Section 11: What the Archive Has Not Yet Revealed

• The full diplomatic record of the separation negotiations in 1965, particularly the discussions between Lee Kuan Yew and Tunku Abdul Rahman, remains partially classified. The Malaysian side of the record is even less accessible.

• The internal deliberations on the timing of PRC recognition -- including the specific communications with Beijing, Taipei, and Jakarta that preceded the 1990 decision -- have not been fully published. The triangular management of the China-Taiwan dimension of Singapore's foreign policy remains among the most closely held areas of policy.

• The complete record of intelligence-sharing arrangements with the United States and other partners is classified and unlikely to be declassified for decades. The depth and character of the intelligence relationship -- often described by analysts as deeper than many formal alliances -- is known in outline but not in detail.

• Internal foreign policy assessments during the Cambodian crisis, particularly any dissenting views on the wisdom of supporting the Coalition Government of Democratic Kampuchea, are not publicly available. Whether there was significant internal debate within the MFA on the moral dimensions of the position remains unknown.

• The diplomatic record of Singapore's engagement with Taiwan -- military training arrangements, unofficial diplomatic contacts, the management of the "one China" framework -- is largely undocumented in the public record. The SAF training programme in Taiwan is acknowledged but its details, and the diplomatic correspondence surrounding it, remain confidential.

• The internal government assessments preceding the Ukraine sanctions decision, including any dissenting views within the Cabinet or civil service, and the extent of consultation with business interests and trading partners, have not been disclosed.

• The full record of water negotiations with Malaysia, including internal assessments of Singapore's bargaining position, contingency planning for various scenarios, and the diplomatic correspondence surrounding the 2002 publication of bilateral communications, remains confidential.

• Oral histories of key diplomatic figures are partially available through the National Archives but remain incomplete. Several significant diplomats from the founding generation were not formally interviewed before their deaths, representing permanent losses to the historical record.

• The internal MFA assessments of ASEAN's institutional effectiveness -- particularly whether Singapore's diplomats have privately concluded that ASEAN's consensus model has become an obstacle to effective action -- would illuminate the gap between public support for ASEAN and private frustration with its limitations.

• The communications surrounding the Terrex incident -- what was said between Singapore and China, what role Hong Kong authorities played independently, and what assurances were given or withheld during the negotiations for the vehicles' return -- remain undisclosed.
