Section 1: Key Takeaways

• Singapore's foreign policy was forged in existential crisis: expelled from Malaysia on 9 August 1965, a Chinese-majority city-state of 1.9 million people wedged between two Malay-Muslim neighbours, with no hinterland, no natural resources, no army, and no certainty of survival.

• S. Rajaratnam, Singapore's first Foreign Minister (1965–1980), established the foundational principles: absolute sovereignty, non-alignment, adherence to international law, multilateralism, and the conviction that a small state's survival depends on a rules-based international order.

• 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, and it remains operative in 2026.

• 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.

• Tommy Koh's leadership in negotiating the United Nations Convention on the Law of the Sea (UNCLOS, 1973–1982) remains Singapore's single greatest individual diplomatic achievement and demonstrated that a small state could shape global governance.

• The balance-of-power strategy — maintaining productive relationships with all major powers while allying formally with none — has been the central organising principle of Singapore's great-power diplomacy from independence to the present US-China rivalry.

• The bilateral relationship with Malaysia is the permanent structural condition of Singapore's foreign policy: the water agreements, the causeway, shared airspace, ethnic ties, and historical grievances make it the relationship that can never be neglected.

• Singapore's response to Russia's invasion of Ukraine in 2022 — imposing autonomous sanctions outside the UN framework for the first time — demonstrated that the country would pay economic costs to defend the principle that large states cannot simply absorb smaller ones.

• The Forum of Small States (FOSS, established 1992) and the Global Governance Group (3G, established 2009) represent Singapore's institutional innovations in multilateral diplomacy, creating platforms for small states to coordinate positions on global issues.

• Key diplomatic figures across six decades — Rajaratnam, Tommy Koh, Chan Heng Chee, George Yeo, K Shanmugam, Bilahari Kausikan, Kishore Mahbubani, and Vivian Balakrishnan — have articulated and adapted these principles while maintaining remarkable continuity of strategic logic.

• Singapore's foreign policy is inseparable from its domestic governance model: the multiracial compact at home constrains and shapes every external relationship, particularly with China, Malaysia, and the Islamic world.

• The transition from a post-colonial to a post-Cold War to a multipolar international order has required continuous recalibration, but the core principles established in 1965 remain recognisable and operative in 2026.

Section 2: The Record in Brief

Singapore's foreign policy is the foreign policy of a state that was never supposed to exist independently. When the Federation of Malaysia expelled Singapore on 9 August 1965, the new country had no foreign ministry, no diplomatic corps, and no international recognition. Its first Foreign Minister, S. Rajaratnam, had been a journalist. Its survival was not assured: Indonesia was in the midst of Konfrontasi, the Philippines had territorial claims in the region, and Singapore's own neighbours regarded it with suspicion as a Chinese outpost in a Malay world.

From this unpromising beginning, Singapore constructed a foreign policy architecture of remarkable sophistication. The core logic was simple and has never changed: a small state without strategic depth depends for its survival on a rules-based international order in which sovereignty is respected, borders are inviolable, and disputes are settled by law rather than force. Every major foreign policy decision Singapore has made — from joining the United Nations on 21 September 1965 to imposing sanctions on Russia in March 2022 — can be traced to this foundational logic.

The architecture has five pillars: sovereign independence (refusing subordination to any power), regional embedding through ASEAN, active multilateralism through the UN system, a balance-of-power approach to great-power relations, and military deterrence through the SAF and security partnerships including the Five Power Defence Arrangements. These pillars were erected in the first decade of independence and have been maintained, reinforced, and adapted — but never abandoned — across six subsequent decades.

The diplomatic record includes extraordinary achievements: UNCLOS, which Tommy Koh shepherded to completion; Singapore's role in launching ASEAN and transforming it from a Cold War alignment into the region's central institution; the management of the Malaysia relationship through crises over water, airspace, territorial claims, and ethnic politics; the construction of a security relationship with the United States that anchors American presence in Southeast Asia without a formal alliance; and the careful management of the China relationship, resisting pressure to be Beijing's proxy while building deep economic ties.

The record also includes tensions, miscalculations, and costs. Relations with Indonesia and Malaysia have periodically descended into acrimony. Singapore's refusal to choose sides has irritated both Washington and Beijing at different moments. The decision to impose Russia sanctions carried real economic costs and drew criticism from partners who preferred to stay silent. The foreign policy establishment has sometimes been accused of excessive caution, of privileging stability over values, of maintaining ties with authoritarian regimes when principle might have demanded otherwise.

What is beyond dispute is that a city-state of 5.9 million people has secured and maintained its sovereignty, prosperity, and international standing for over sixty years in one of the world's most strategically contested regions — an outcome that almost no observer predicted in 1965.

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, through which roughly a quarter of global trade passes. 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.

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 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.

Lee Kuan Yew articulated this constraint with characteristic bluntness: Singapore could never be seen as a "third China." It had to be a multiracial, multilingual, secular state — not because of abstract idealism but because the alternative was existential danger. This domestic imperative became the foundational constraint on foreign policy. Singapore would recognise the People's Republic of China only after Indonesia did so (which happened in 1990, making Singapore the last ASEAN state to establish formal diplomatic relations with Beijing). Singapore would insist on its multiracial identity in every international forum. And Singapore would never allow itself to be used as a proxy for any external power — Chinese, Western, or otherwise.

The Post-Colonial Inheritance

Singapore inherited from the British colonial period several assets and several liabilities. The assets included the English language as a working language of government, 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 traumatic: the British military presence had accounted for roughly 20 per cent of Singapore's GDP and employed tens of thousands. Its departure 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.

Section 5: The Primary Record

1965–1971: Founding the Framework

The UN Admission and Rajaratnam's Vision

Singapore was admitted to the United Nations on 21 September 1965, barely six weeks after independence. Rajaratnam's maiden address to the UN General Assembly, delivered on 21 September 1965, was a foundational statement of Singapore's foreign policy philosophy. 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.

Rajaratnam's speech contained a passage that became the philosophical anchor of Singapore's multilateral diplomacy: the argument that in a world of nuclear weapons and superpower competition, small states could survive only if the international system was governed by rules rather than power alone. This was not idealism — Rajaratnam was deeply pragmatic — 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 Doctrine

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 over time. By the 1980s, Singapore's strategic thinkers had moved beyond the "poisonous shrimp" to what some termed the "porcupine" model — not merely poisonous but visibly armed with quills, deterring not through the threat of post-mortem revenge but through the certainty of immediate pain. By the 2000s, the SAF's technological capabilities had grown to the point where Singapore possessed genuine military advantages in specific domains — air power, naval surveillance, cyber capabilities — that made the deterrence credible in ways the earliest planners could not have imagined.

ASEAN Co-founding (1967)

The decision to co-found the Association of Southeast Asian Nations on 8 August 1967 was Singapore's most consequential early diplomatic act. ASEAN was formed by the foreign ministers of Indonesia, Malaysia, the Philippines, Singapore, and Thailand through the Bangkok Declaration. 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 or a temporary arrangement. 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 relationship with Indonesia, which had only recently ended Konfrontasi and whose attitude toward Singapore remained uncertain.

Rajaratnam was central to negotiating the terms of Singapore's participation. He 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 process, has been both Singapore's greatest protection within the organisation and, at times, its greatest frustration.

The transformation of ASEAN from a loose anti-communist grouping into the central institution of Southeast Asian regionalism is one of the great diplomatic achievements of the post-colonial era, and Singapore has been both a beneficiary and a driver of that transformation. Singapore pushed for ASEAN economic integration through the ASEAN Free Trade Area (AFTA, 1992), the ASEAN Economic Community (AEC, 2015), and the Regional Comprehensive Economic Partnership (RCEP, 2020). It championed the ASEAN Regional Forum (ARF, 1994) and the East Asia Summit (EAS, 2005) as mechanisms for engaging the great powers within an ASEAN-centred framework.

The Five Power Defence Arrangements (1971)

When Britain withdrew its military forces from East of Suez, the Five Power Defence Arrangements (FPDA) were established in 1971 among the United Kingdom, Australia, New Zealand, Malaysia, and Singapore. The FPDA was not a formal alliance with a mutual defence clause — it was a consultative arrangement under which the five parties agreed to consult in the event of an armed attack or threat of attack on Malaysia or Singapore.

For Singapore, the FPDA served multiple purposes: it maintained a residual external security commitment during the vulnerable early years of SAF development; it provided a framework for military exercises and interoperability with advanced Western militaries; and it signalled to potential adversaries that Singapore was not alone. The FPDA has been maintained and periodically updated for over fifty years, making it one of the longest-standing security arrangements in Asia. As of 2026, it continues to conduct annual integrated exercises involving air, naval, and land forces.

1971–1990: The Cold War Years

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 and the overthrow of the Khmer Rouge regime. Singapore, under Foreign Minister Rajaratnam and subsequently Suppiah Dhanabalan, led ASEAN's diplomatic campaign to deny the Vietnamese-installed government international recognition and to insist on Vietnam's withdrawal.

This was a complex and morally fraught position. The Khmer Rouge had committed genocide, and Vietnam's invasion had ended it. Yet Singapore insisted that the principle at stake — that one country could not simply invade and occupy another — was more important than the character of the regime that had been overthrown. Rajaratnam argued that if the international community accepted the principle that a large state could invade a small state for any reason, however sympathetic, then no small state was safe.

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. Singapore's response, articulated most forcefully by Rajaratnam and later by Bilahari Kausikan, was that the alternative — accepting the legitimacy of Vietnamese military occupation — would have established a precedent that directly threatened Singapore's own sovereignty.

The Cambodian issue was ultimately resolved through the Paris Peace Agreements of 1991, which Singapore supported. The episode demonstrated both the strengths and the costs of Singapore's principled approach to sovereignty: the principle was upheld, but the moral complexities were real and the criticism was not unfounded.

Tommy Koh and UNCLOS

Singapore's greatest individual diplomatic achievement belongs to Tommy Koh, who served as President of the Third United Nations Conference on the Law of the Sea from 1981 to 1982, succeeding Hamilton Shirley Amerasinghe of Sri Lanka. Koh presided over the final and most complex phase of negotiations that produced the United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982.

UNCLOS established a comprehensive legal framework for the world's oceans, governing everything from territorial waters and exclusive economic zones to deep-sea mining and marine environmental protection. 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's achievement was not merely procedural. He navigated negotiations involving over 160 countries with fundamentally different interests — landlocked states versus maritime states, developed nations versus developing nations, states with extensive coastlines versus those without. He developed what he called 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 not only participate in but actually lead the creation of global governance frameworks. Tommy Koh's personal diplomacy — his patience, his intellectual rigour, his capacity to bridge competing interests — became a model for Singapore's subsequent approach to multilateral negotiations.

Koh subsequently served as Singapore's Ambassador to the United States (1984–1990) and as Singapore's chief negotiator on numerous other multilateral issues, including the Uruguay Round of GATT negotiations and various environmental agreements. He remained, into his nineties, one of Singapore's most prominent public intellectuals and diplomats.

The Bilateral Relationships

Malaysia: The Permanent Bilateral

The relationship with Malaysia is Singapore's most important, most complex, and most emotionally charged bilateral relationship. It is the relationship that can never be set aside, because the two countries are physically, economically, ethnically, and historically intertwined in ways that no diplomatic framework can fully manage.

The separation in 1965 left unresolved issues that have shaped the bilateral relationship ever since. The most important is water. Under agreements signed in 1961 and 1962, Singapore obtained the right to draw water from Johor at extremely low prices. The 1961 agreement expired in 2011; the 1962 agreement runs until 2061. These agreements are guaranteed under the Separation Agreement registered with the United Nations, giving them the force of international treaty obligations.

Water has been wielded as political leverage by Malaysian leaders repeatedly. Mahathir Mohamad raised the water price issue during periods of bilateral tension. The issue became acute in the early 2000s when negotiations over water pricing, the relocation of Malaysian customs from Tanjong Pagar railway station, and airspace disputes converged into a period of sustained diplomatic friction. For Singapore, water dependency was an existential vulnerability that drove the development of alternative water sources — the NEWater programme (recycled water, operational from 2003), desalination plants, and reservoir expansion — to reduce dependence on Malaysian supply before the 2061 agreement expires.

Other recurring bilateral issues have included the status of Pedra Branca (resolved by the International Court of Justice in 2008 in Singapore's favour, with the Middle Rocks awarded to Malaysia), airspace management, the KTM railway land dispute (resolved in 2010), the High Speed Rail project (cancelled in 2021 after repeated delays), and competing maritime claims.

The relationship has also been characterised by deep economic interdependence. Hundreds of thousands of Malaysians commute daily to work in Singapore. Trade flows are among the largest bilateral flows in Southeast Asia. Singapore is one of the largest foreign investors in Malaysia. These ties create shared interests that moderate the political tensions but do not eliminate them.

Under the Najib government (2009–2018) and subsequently under Anwar Ibrahim (from 2022), relations improved significantly, with both sides emphasising economic cooperation over historical grievances. Yet the structural dynamics remain: Malaysia is the larger neighbour, the water supplier, the source of labour, and the country whose domestic politics most directly affect Singapore's security environment.

Indonesia: From Konfrontasi to Partnership

The relationship with Indonesia has been the other critical bilateral dynamic. Indonesia's Konfrontasi campaign (1963–1966) — which included bombings in Singapore — cast a long shadow over the early years. The execution of two Indonesian marines convicted of the MacDonald House bombing in 1968 provoked a severe diplomatic crisis, with Indonesia suspending relations and mobs attacking the Singapore embassy in Jakarta.

Relations were normalised under President Suharto, and the relationship developed into a productive if sometimes difficult partnership. Economic complementarity was significant: Singapore's port served as Indonesia's primary trading gateway, and Singapore capital flowed into Indonesian industry, resources, and real estate. The relationship was periodically strained by issues including sand exports (Indonesia banned sand exports to Singapore, affecting land reclamation), the haze from Indonesian forest fires (a persistent irritant from the 1990s onward), extradition and defence cooperation disagreements, and the naming of Indonesian naval vessels after the marines who had bombed MacDonald House.

The post-Suharto era brought both opportunities and uncertainties. Indonesia's democratisation meant that foreign policy was subject to more complex domestic political pressures. Relations under Presidents Habibie, Megawati, Yudhoyono, Jokowi, and Prabowo have varied in warmth but have generally trended toward deeper institutionalisation, including a defence cooperation agreement, joint development of special economic zones in the Riau Islands, and coordination on counter-terrorism.

The United States: Strategic Anchor

Singapore's relationship with the United States has been its most important great-power relationship in strategic terms, though this has always been managed with studied informality. There is no formal alliance, no mutual defence treaty, and no status of forces agreement of the kind that governs US military presence in Japan, South Korea, or the Philippines.

What exists instead is a dense network of practical cooperation. The 1990 Memorandum of Understanding (updated in 2005 and 2019) provides US naval and air forces with access to Singapore's military facilities. Changi Naval Base, completed in 2004, was explicitly designed to accommodate US aircraft carriers. US Littoral Combat Ships have been rotationally deployed to Singapore since 2013. The two countries conduct extensive joint military exercises, intelligence sharing, and defence technology cooperation.

The relationship extends well beyond defence. The US-Singapore Free Trade Agreement (2003) was the first such agreement between the United States and an Asian country. Economic ties are substantial: the United States is one of the largest foreign investors in Singapore, and Singapore is one of the largest Asian investors in the United States. Singapore has consistently supported American engagement in the Asia-Pacific, viewing US presence as essential to the regional balance of power.

Singapore has also been a reliable partner in counter-terrorism since 2001, including the disruption of a Jemaah Islamiyah cell that had planned attacks on US and other Western targets in Singapore. The relationship survived disagreements — the US criticised Singapore over the Michael Fay caning incident in 1994 and periodically raises concerns about media freedom and civil liberties — but the strategic alignment has been consistent.

Under the Trump administration's first term (2017–2021) and the Biden administration (2021–2025), Singapore navigated the increasingly explicit US framing of the Indo-Pacific as a domain of strategic competition with China. Singapore resisted pressure to formally align with either the US or China, while practically deepening defence cooperation with the United States and maintaining its position that American presence in the region was stabilising.

China: Managed Engagement

Singapore's relationship with the People's Republic of China is the most diplomatically sensitive and the most frequently misunderstood. External observers — particularly in Beijing — have sometimes assumed that ethnic affinity translates into political alignment. Singapore's leaders have spent sixty years pushing back against this assumption.

Singapore was the last ASEAN member to establish formal diplomatic relations with China, doing so only in October 1990 — after Indonesia had restored relations. This was deliberate: Lee Kuan Yew insisted that Singapore could not be seen as leading ASEAN toward China, as this would confirm the suspicion that Singapore was a Chinese stalking horse in Southeast Asia.

Once relations were established, they deepened rapidly. China became Singapore's largest trading partner. The Suzhou Industrial Park (1994) and the Sino-Singapore Tianjin Eco-City (2008) were government-to-government projects that transferred Singapore's development model to Chinese contexts. The Chongqing Connectivity Initiative (2015) added a third such project. Singapore became a major hub for RMB internationalisation and Chinese outward investment.

Yet the relationship has been punctuated by significant tensions. In 2016–2017, relations deteriorated sharply after Singapore's principled position on the South China Sea disputes (particularly following the Permanent Court of Arbitration ruling on Philippines v. China) drew Beijing's ire. Nine Terrex armoured personnel carriers belonging to the SAF were detained at Hong Kong's Kwai Chung port in November 2016 while being shipped back from training in Taiwan — an incident widely interpreted as Chinese pressure over Singapore's South China Sea stance and its military relationship with Taiwan.

The incident was resolved in early 2017, and relations were subsequently repaired. But it illustrated the fundamental tension: Singapore maintains an unofficial but substantive relationship with Taiwan, including SAF training facilities on the island, while also developing deep economic ties with the PRC. Managing this triangle requires constant diplomatic calibration.

Singapore's position on the South China Sea has been consistent: it takes no position on the sovereignty claims of competing claimants but insists on freedom of navigation, the applicability of international law (particularly UNCLOS), and the peaceful settlement of disputes. This position has drawn criticism from China, which views it as pro-American, and occasionally from ASEAN partners who wish Singapore would be more accommodating of Chinese sensitivities.

India: CECA and Beyond

Singapore's relationship with India deepened significantly from the 1990s onward, driven by India's economic liberalisation and Singapore's strategic interest in diversifying its great-power relationships. The Comprehensive Economic Cooperation Agreement (CECA), signed in 2005, was India's first comprehensive free trade agreement with any country.

CECA became domestically controversial in Singapore in the late 2010s and early 2020s, as public concern grew over the number of Indian professionals entering Singapore on employment passes. Critics argued that CECA facilitated an influx of Indian workers who displaced Singaporean professionals, particularly in the information technology and financial services sectors. The government repeatedly clarified that CECA did not provide for free movement of labour and that employment pass holders were subject to standard regulatory requirements, but the issue became entangled with broader anxieties about immigration, job competition, and ethnic composition.

The CECA controversy illustrated a recurring tension in Singapore's foreign policy: trade agreements that serve strategic and economic objectives at the national level can generate domestic political costs that constrain future diplomatic flexibility. The government's response — tightening employment pass criteria while defending the strategic value of the India relationship — was characteristic of Singapore's approach to managing the domestic-foreign policy interface.

Beyond CECA, the India relationship encompasses defence cooperation (including naval exercises and training exchanges), technology partnerships, and coordination in multilateral forums. Singapore has consistently supported India's engagement in East Asian regional architecture, including the East Asia Summit.

1990–2010: Post-Cold War Recalibration

The end of the Cold War required fundamental recalibration. The bipolar order that had structured international relations since 1945 gave way to a period of American unipolarity that Singapore's strategic thinkers regarded as transitional. The key question was what would come next — and how Singapore should position itself for a multipolar or a US-China bipolar future.

Several developments marked this period. The resolution of the Cambodian conflict removed the issue that had dominated ASEAN's agenda for a decade. The admission of Vietnam, Laos, Myanmar, and Cambodia to ASEAN (1995–1999) transformed the organisation from a five-member grouping into a ten-member bloc spanning all of Southeast Asia. Singapore supported this enlargement while recognising that it would make consensus more difficult and reduce ASEAN's coherence.

The Asian Financial Crisis of 1997–1998 tested regional solidarity and exposed the limits of ASEAN's institutional capacity. Singapore emerged from the crisis in better shape than most of its neighbours, but the experience reinforced two lessons: that economic resilience was a component of national security, and that regional instability could spread regardless of an individual country's prudence.

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 issues including climate change, digital governance, and reform of international institutions.

2010–2026: The US-China Rivalry and Singapore's Positioning

The defining strategic challenge of this period 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 speech at the Shangri-La Dialogue in 2019 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.

This position has been tested from both sides. The United States has sought to build coalitions — the Quad, AUKUS, the Indo-Pacific Economic Framework (IPEF) — that are widely perceived as directed at China. Singapore has participated selectively (joining IPEF while maintaining distance from overtly military-focused groupings). China has pressured ASEAN states to resist US initiatives and has used economic leverage to reward compliance and punish independence.

Singapore's hosting of the historic Trump-Kim summit in June 2018 was a diplomatic coup that demonstrated Singapore's value as a neutral venue and its capacity to manage complex security logistics. It reinforced Singapore's positioning as a hub for great-power diplomacy rather than a participant in great-power competition.

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, initially comprising 30 countries, advocated for G20 accountability and transparency and for small-state inclusion in global governance processes.

The Russia-Ukraine Response (2022)

Singapore's response to Russia's invasion of Ukraine in February 2022 was a watershed moment in its foreign policy. 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 principle that undergirds Singapore's entire foreign policy: that the sovereignty and territorial integrity of states must be respected, and that large countries cannot simply invade and absorb smaller ones. Balakrishnan told Parliament: "This is an existential issue for us. If we do not stand up when principles are violated, we will lose our right to speak up when the same principles are at stake for us."

The sanctions were carefully calibrated: significant enough to be meaningful but not so broad as to sever all ties with Russia. Singapore maintained diplomatic relations with Moscow. The decision drew some criticism from business interests with Russian exposure and from observers who noted that Singapore had not imposed similar sanctions on other large-power military actions. The government's response was that the Ukraine invasion was a clear-cut case of one sovereign state attempting to conquer and annex another — precisely the scenario that most directly threatened Singapore's own existence as a small state.

PM Lee Hsien Loong's statement reinforced the point: "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."

Section 6: Key Figures

S. Rajaratnam (1915–2006)

Foreign Minister (1965–1980), Second Deputy Prime Minister (1980–1985). A journalist by training (he had worked for the Malayan Tribune and the Singapore Standard), Rajaratnam was one of the PAP's founding members and its chief ideologist. As Foreign Minister, he designed the architecture of Singapore's external relations: the commitment to non-alignment, the emphasis on international law, the strategy of embedding Singapore in multilateral institutions. His maiden speech at the UN General Assembly in 1965 established the intellectual framework that guides Singapore's diplomacy to this day. He was also the author of the Singapore Pledge, drafted in 1966, which expressed the multiracial vision that constrains foreign policy. Rajaratnam combined intellectual depth with diplomatic toughness: he led ASEAN's response to the Vietnamese invasion of Cambodia and was willing to sustain moral criticism to defend the sovereignty principle. His collected speeches and writings, published posthumously, remain essential texts for understanding Singapore's strategic worldview.

Tommy Koh (b. 1937)

Ambassador-at-Large, Singapore's most decorated diplomat. Dean of the Faculty of Law at the University of Singapore before entering diplomacy, Koh served as Permanent Representative to the United Nations (1968–1971, 1974–1984), Ambassador to the United States (1984–1990), and subsequently as Ambassador-at-Large and Special Adviser to the Institute of Policy Studies. His presidency of the Third UN Conference on the Law of the Sea (1981–1982) was his defining achievement. He also chaired the Preparatory Committee and the Main Committee of the 1992 Earth Summit in Rio de Janeiro. Koh has been a persistent advocate for the proposition that small states can and must shape international law, and that diplomatic excellence is a form of national security.

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 before entering government service, Chan built the Singapore-US relationship into its mature form, managing the relationship through the George W. Bush, Clinton, and Obama administrations. She was instrumental in negotiating the US-Singapore FTA and deepening defence cooperation. Her intellectual contributions — including her early academic work on Singapore's political system — gave her a dual credibility as both scholar and practitioner.

George Yeo (b. 1954)

Foreign Minister (2004–2011). A former brigadier-general, Yeo brought a distinctive intellectual style to foreign policy, emphasising civilisational dialogue, ASEAN community-building, and engagement with China. He championed the ASEAN Charter (signed 2007), pushed for deeper ASEAN integration, and managed the complex relationship with China during a period of rapidly growing economic interdependence. Yeo lost his parliamentary seat in the 2011 general election, ending his ministerial career. He subsequently took on roles in the private sector and in Hong Kong, becoming a somewhat unconventional figure in Singapore's diplomatic establishment.

K Shanmugam (b. 1959)

Foreign Minister (2008–2011) and subsequently Minister for Home Affairs and Minister for Law. Shanmugam brought a lawyer's precision to foreign policy discourse. His parliamentary speeches on international law, sovereignty, and Singapore's position on great-power competition are among the most analytically rigorous statements of Singapore's foreign policy principles. He was particularly articulate on the question of why small states must insist on the rule of law in international affairs.

Vivian Balakrishnan (b. 1961)

Foreign Minister from 2015. A former ophthalmologist, Balakrishnan managed Singapore's foreign policy during the most challenging period of US-China competition, navigated the COVID-19 pandemic's impact on international relations, and led Singapore's response to the Russia-Ukraine crisis. His parliamentary statement on the Ukraine sanctions in February 2022 was widely cited internationally as a model of principled small-state foreign policy. He also managed the complex diplomacy of hosting the Trump-Kim summit in 2018.

Bilahari Kausikan (b. 1954)

Second Permanent Secretary for Foreign Affairs, subsequently Ambassador-at-Large. Kausikan is arguably the most intellectually influential figure in Singapore's foreign policy establishment after Rajaratnam. His essays and speeches — delivered with a directness unusual in diplomatic circles — have articulated the realist foundations of Singapore's foreign policy with exceptional clarity. His critique of Western human rights universalism at the 1993 Vienna World Conference on Human Rights (arguing that Asian states had legitimate grounds for contextualising rights within their own cultural and developmental frameworks) was controversial but influential. His writings on the US-China rivalry, on ASEAN's limitations, and on the psychology of small-state diplomacy constitute an essential body of strategic thought.

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. Mahbubani became one of the most prominent international voices arguing for a rebalancing of global governance in favour of Asian and developing-world perspectives. His books — including Can Asians Think? (1998), The New Asian Hemisphere (2008), and Has China Won? (2020) — provoked debate about Western assumptions of global leadership. His relationship with the Singapore government became more complex over time, as his advocacy for accommodation with China sometimes sat uneasily with Singapore's official balance-of-power position.

Section 7: Stories and Anecdotes

Rajaratnam at the United Nations, 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: it established Singapore as a responsible member of the international community and signalled that the new state would seek security through institutions rather than through subservience to any patron.

The Water Negotiations

In 2002, during a period of sharp bilateral tension, Malaysian Prime Minister Mahathir Mohamad publicly linked the water issue to other disputes, suggesting that Malaysia might not renew the water agreements unless a comprehensive package of issues was resolved on terms favourable to Kuala Lumpur. Singapore's response was to publish the full correspondence between the two governments — an unusual step in Asian diplomacy, where discussions are traditionally kept confidential. The publication was intended to demonstrate that Singapore had negotiated in good faith and that Malaysia's public demands contradicted its private positions. The move was effective diplomatically but poisoned the personal relationship between the two governments for the remainder of Mahathir's tenure. It also accelerated Singapore's investment in water self-sufficiency. Lee Kuan Yew later said that water was "an existential issue" — that Singapore could not afford to be hostage to a resource controlled by another sovereign state.

Tommy Koh's Marathon

The final session of the UNCLOS conference, 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 an understanding that every delegation, however small, had legitimate interests that needed to be reflected in the text. "You cannot bully countries into agreeing," he said. "You have to persuade them that the outcome serves their interests." The successful conclusion of UNCLOS was celebrated in Singapore as proof that a small state could play a role on the world stage disproportionate to its size.

The Terrex Incident

In November 2016, nine Singapore Armed Forces Terrex infantry carrier vehicles were detained by Hong Kong customs while being shipped back from training exercises in Taiwan. The timing — shortly after Singapore's expressions of support for the international tribunal ruling against China's South China Sea claims — was widely interpreted as a signal from Beijing. Singapore's response combined quiet diplomacy with public firmness: Defence Minister Ng Eng Hen stated that the SAF's training arrangements were "long-standing" and that Singapore would not be pressured into changing them. The vehicles were returned in January 2017, and relations were subsequently repaired, but the incident remained a reference point for the pressures Singapore faces in managing the cross-strait dimension of its China policy.

The Trump-Kim Summit, 2018

When the United States and North Korea needed a venue for the first-ever summit between their leaders, Singapore was chosen. The decision reflected Singapore's positioning as a country trusted by both sides, with diplomatic relations with both the United States and North Korea. The logistics were formidable: security for two of the world's most protected leaders, media management for several thousand journalists, and the diplomatic sensitivity of hosting a meeting whose outcome was entirely uncertain. Singapore bore the estimated S$20 million cost as an investment in its reputation as a neutral venue for high-stakes diplomacy.

Section 8: Arguments and Rhetoric

Logos: The Small-State 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, by every Foreign Minister and by the leading strategic thinkers.

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."

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."

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."

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. This is not merely rhetorical effect; it reflects a genuine assessment of vulnerability.

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."

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.

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."

Section 9: The Contested Record

The Cambodia Controversy

Singapore's role in the Cambodian diplomacy of the 1980s remains contested. The principled case — that accepting Vietnam's invasion would have established a dangerous precedent for small-state sovereignty — is logically coherent. The moral case against Singapore's position — that it effectively supported maintaining the Khmer Rouge's UN seat while the regime's victims remained unacknowledged — is also compelling. Academic assessments remain divided, with some scholars (such as Ang Cheng Guan) defending the ASEAN position and others arguing that Singapore prioritised abstract principle over human suffering.

Relations with Authoritarian Regimes

Singapore's pragmatic engagement with authoritarian governments — from Myanmar's military junta to China's Communist Party to various Middle Eastern monarchies — has drawn criticism from human rights organisations and Western commentators. Singapore's response has been consistent: it does not condition diplomatic relations on domestic governance models, and it argues that engagement is more likely to produce positive change than isolation. Critics counter that this position conveniently aligns with commercial interests and that Singapore is selective in its application of the sovereignty principle.

The "Asian Values" Debate

In the 1990s, Singapore was closely associated with the "Asian values" argument — the proposition that East Asian societies had distinct cultural values (emphasising community, order, and collective welfare over individual rights) that justified governance models different from Western liberal democracy. Kishore Mahbubani and Bilahari Kausikan were prominent advocates of versions of this argument. Western critics accused Singapore of using cultural relativism to justify authoritarianism. The debate has faded somewhat since the 1990s but resurfaces whenever Singapore's domestic governance is scrutinised in international forums.

The US-China Balance: Too Close to Washington?

Some analysts — particularly those sympathetic to China's perspective — argue that Singapore's professed neutrality masks a de facto strategic alignment with the United States. They 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 its reluctance to criticise US military actions (in contrast to its outspoken criticism of Russia's Ukraine invasion). Singapore's leaders reject this characterisation, noting that Singapore also maintains deep economic ties with China, that it has resisted joining explicitly anti-China groupings, and that it has publicly criticised US policies when warranted.

Domestic Costs of Foreign Policy

The CECA controversy revealed a gap between foreign policy elites and public sentiment. The government's framing of CECA as a strategic initiative serving national interests was challenged by citizens who experienced its effects as job competition and demographic change. More broadly, critics have argued that Singapore's foreign policy establishment — small, elite, and insulated from electoral pressure — has sometimes pursued strategic objectives without adequate consideration of domestic political costs. The government's response has been to tighten immigration controls while defending the strategic logic, but the tension between elite foreign policy and popular sentiment remains a live issue.

Section 10: Outcomes and Evidence

Diplomatic Network

As of 2025, Singapore maintains diplomatic relations with 192 countries and operates approximately 50 overseas missions (embassies, high commissions, and consulates). For a country of 5.9 million people, this is an extraordinarily dense diplomatic network.

Trade Agreements

Singapore has signed 27 bilateral and regional free trade agreements, covering its major trading partners. It is a member of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), the Regional Comprehensive Economic Partnership (RCEP), and has bilateral FTAs with the United States, the European Union (EUSFTA, 2019), China, Japan, India, South Korea, Australia, and New Zealand, among others. Total trade as a percentage of GDP consistently exceeds 300 per cent — among the highest in the world.

Military Partnerships

The SAF conducts regular bilateral exercises with the United States, Australia, India, France, the United Kingdom, and numerous other countries. Singapore's defence spending has been maintained at approximately 3 per cent of GDP — higher than the NATO benchmark — reflecting the continued centrality of deterrence to the foreign policy framework.

Multilateral Positions

Singapore has served on the UN Security Council twice (2001–2002 and a campaign seat in subsequent years), has held leadership positions in numerous UN bodies, and has been a consistent advocate for small-state representation in international governance institutions. The Forum of Small States has grown from an initial membership of about 25 countries to over 100.

International Rankings

Singapore consistently ranks among the world's most globalised economies (Zurich ETH KOF Globalisation Index), the most efficient ports (Maritime and Port Authority rankings), and the most connected air hubs (International Air Transport Association data). These rankings reflect the success of a foreign policy strategy that has prioritised economic connectivity as a component of national security.
