Regionalisation of World Politics

Concepts and Definitions

The regionalisation of world politics refers to the intensification of political, economic, and social interdependence among states within a specific geographic area, leading to the formation of regional institutions, agreements, and shared identities that shape international affairs alongside global institutions. Understanding this phenomenon requires distinguishing between several related but distinct concepts. A region, in Joseph Nye's formulation, is a limited number of states linked by a geographical relationship and by a degree of mutual interdependence. Regionalism is the political and ideological commitment to cooperate and integrate with countries in one's region - a common sense of identity and purpose among states in a geographic area, manifested through the creation of institutions and policies for collective action. Regionalisation is the process by which regions emerge and strengthen through increasing interactions; it may be organic and bottom-up, arising from trade and investment flows, or deliberate and state-led, responding to security imperatives. Regional integration refers to the deepening of cooperation between states through formal agreements and institutions, involving stages such as free trade areas, customs unions, common markets, and potentially full economic and political union.

Globalisation and regionalisation are not simply opposed processes. Globalisation denotes the widening and deepening of worldwide interconnectedness across economic, social, technological, and political spheres. Regionalisation, rather than undermining globalisation, frequently functions as one of its building blocks: regional arrangements provide the institutional infrastructure within which market integration, norm diffusion, and political cooperation can proceed more rapidly and with greater mutual trust than at the global level. The dominant scholarly consensus today treats the two as complementary and mutually reinforcing processes rather than rivals.

Why States Pursue Regionalisation

States pursue regional arrangements for a combination of economic, security, political, and identity-based motivations. The economic rationale is foundational: by integrating markets with neighbours, states can increase trade and investment, achieve economies of scale, develop regional value chains, and collectively attract foreign direct investment. The boost to North American trade under NAFTA - from roughly $300 billion to over $1 trillion between 1994 and 2011 - illustrates this dynamic. Regional blocs also provide greater bargaining power in global trade negotiations, allowing smaller economies to leverage their collective weight in ways unavailable to them individually.

Security provides a second major motivation. The European Union's foundational logic was to bind historically antagonistic states so closely together through economic interdependence that war between them would become unthinkable. Karl Deutsch theorised this outcome as a security community - a group of states among which peaceful resolution of conflicts has become so institutionalised that war is effectively ruled out as a policy option. Regional arrangements also allow states to coordinate defence, intelligence-sharing, and crisis management in ways that strengthen their collective security without the limitations of purely bilateral agreements.

Geopolitical considerations increasingly drive regional initiatives. Smaller states gain influence and protection by aligning with larger neighbours and speaking with a collective voice. Larger powers use regional leadership to extend their influence. Great-power competition generates its own pressure toward regionalisation: the United States has promoted the Indo-Pacific Economic Framework partly to counterbalance China's growing economic influence in Asia; India has championed BIMSTEC as an alternative regional architecture when SAARC stalled due to Pakistan-related tensions. Shared identity - whether cultural, linguistic, historical, or civilisational - provides a further motivation, as in the case of pan-Arab solidarity behind the Arab League or Islamic identity in the Organisation of Islamic Cooperation.

Theoretical Frameworks

The theoretical study of regional integration was inaugurated by Ernst Haas in The Uniting of Europe (1958), which developed neofunctionalism as the first systematic theory of the integration process. Haas argued against both classical realism - which held that states act solely to maximise power in an anarchic system - and liberal idealism - which naively hoped that law and diplomacy alone could secure peace. Neofunctionalism instead proposed that integration occurs when domestic societal groups and interest-based actors, including bureaucrats, business associations, and trade unions, perceive supranational institutions as better platforms for realising their goals than purely national ones. As integration succeeds in one functional area such as coal and steel, it creates pressure to integrate related sectors such as energy, transport, and eventually monetary policy. This dynamic, which Haas termed the spill-over effect, produces a self-sustaining logic of deepening cooperation that gradually shifts political authority and loyalty upward from national to supranational institutions. Haas later revised neofunctionalism to incorporate constructivist insights, acknowledging that interests and identities are not fixed but evolve through the experience of cooperation itself, and that integration can stall or reverse as well as advance. Haas's core question - how do sovereign states choose to become less sovereign? - remains the animating question of integration theory.

Karl Deutsch's contribution was the concept of the security community, derived from his study of transactions, communications, and mutual responsiveness among states in the North Atlantic region. Deutsch argued that when the volume of transactions - trade, migration, communications, tourism - between states crosses a threshold, it produces a pluralistic security community in which war ceases to be thinkable as a means of resolving disputes. The sociological and communicative processes of integration, not merely the formal institutional architecture, are what ultimately determine whether a region becomes a genuine community.

The distinction between old regionalism and new regionalism captures important historical shifts in how regions are organised. Old regionalism, the dominant form during the Cold War, was state-centric, top-down, and largely driven by geopolitical alignments within the bipolar order. Regional organisations in this phase served primarily as instruments of bloc cohesion, and economic arrangements tended to be protectionist. New regionalism, gaining momentum after the Cold War, is multi-dimensional, involving non-state actors alongside states, generally more open to the global economy, responsive to social and economic demands from within regions, and allowing overlapping memberships and variable geometry across a wider range of issue areas.

The European Union: The Standard of Deep Integration

The European Union is widely regarded as the most advanced example of regional integration in the world. Its origins lie in the determination of post-war European statesmen to prevent the catastrophic interstate conflicts that had devastated the continent twice in the first half of the twentieth century. Integration began in the coal and steel sectors with the European Coal and Steel Community of 1951, on the neofunctionalist logic that binding together the core industrial inputs for modern warfare would make future Franco-German conflict materially impossible. The Treaty of Rome of 1957 established the European Economic Community. The Single European Act of 1987 set the objective of completing the single internal market. The Maastricht Treaty of 1992 transformed the EEC into the European Union and established the framework for a common currency and common foreign and security policy. The Lisbon Treaty of 2007 clarified the division of competences, gave the EU full legal personality, and streamlined its institutional architecture.

The EU's institutional architecture uniquely combines supranational and intergovernmental elements. The European Commission proposes legislation and guards the treaties. The European Parliament, directly elected by EU citizens, co-legislates with the Council of the EU. The European Court of Justice ensures uniform interpretation and enforcement, with its doctrines of direct effect and supremacy of EU law establishing that EU law overrides inconsistent national law. Twenty-one member states, the latest being Bulgaria from 1 January 2026, share the euro and a common monetary policy administered by the European Central Bank. The Schengen Agreement enables passport-free travel across most of the EU.

The EU's achievements are substantial. It has maintained peace among its members for over seven decades - earning the Nobel Peace Prize in 2012. The single market, with a combined GDP of approximately twenty trillion dollars and four hundred and fifty million people, constitutes one of the largest economic units in the world; intra-EU trade accounts for roughly sixty percent of members' total trade. The EU speaks with a unified voice in the WTO, has negotiated major free trade agreements globally, and was central to securing the Paris Climate Agreement. Its structural and cohesion funds actively reduce development disparities between richer and poorer member regions.

The EU's challenges are equally significant. Brexit - the United Kingdom's departure in 2020, driven by grievances over sovereignty, immigration, and the democratic deficit of EU institutions - was the first reversal in the EU's history and energised Eurosceptic movements across the continent. The Eurozone crisis beginning in 2009 exposed the structural flaw of monetary union without fiscal union, generating severe north-south rifts over Greek and other sovereign debt bailouts. The 2015-16 migration surge strained free movement principles and fuelled nationalist politics. Russia's invasion of Ukraine in 2022 forced costly energy decoupling and underlined the EU's continued dependence on NATO for ultimate security guarantees.

Energy Security after the Ukraine War: REPowerEU

Russia's invasion of Ukraine in February 2022 exposed the EU's dependence on Russian energy. In 2021 Russia supplied about 45 per cent of EU gas imports, and Germany, the largest consumer, had no LNG terminal. When Moscow cut pipeline flows, prices spiked and energy-intensive industry faced closures. The Commission responded with REPowerEU in May 2022, built on three lines of action:

• Diversification: LNG from the United States and Qatar, more pipeline gas from Norway, Algeria and Azerbaijan, new import terminals and joint gas purchasing.
• Saving energy: a voluntary 15 per cent cut in gas demand and a rule that storage be filled to 90 per cent before each winter. Demand fell by about 17 per cent between August 2022 and January 2025.
• Renewables: faster permitting and higher targets for solar, wind, heat pumps and hydrogen, financed partly through the Recovery and Resilience Facility.

Russia's share of EU gas imports fell to about 12 per cent in 2025. A regulation approved by the European Parliament in December 2025 sets a ban on Russian LNG imports by the end of 2026 and on pipeline gas by 30 September 2027. The costs were high: inflation, a widening competitiveness gap with the US and China, and resistance from Hungary and Slovakia, which still rely on Russian oil.

Trump's Return and the Push for European Defence and Revival

Donald Trump's second term from January 2025 brought tariff threats, doubts about the US guarantee to NATO and a pause in US military aid to Ukraine in March 2025. European leaders read this as a signal that the Union must provide for its own security. The main responses were:

• ReArm Europe (renamed Readiness 2030): proposed by Ursula von der Leyen on 4 March 2025 to mobilise up to 800 billion euros, mainly by letting member states raise defence spending without breaching EU fiscal rules (a potential 650 billion euros over four years). It was renamed after objections from Italy and Spain.
• SAFE (Security Action for Europe): adopted on 27 May 2025, it offers 150 billion euros in long-term loans for joint procurement, provided weapons have at least 65 per cent European components. Canada joined in December 2025.
• National and NATO commitments: Germany amended its constitution in March 2025 to exempt defence spending above 1 per cent of GDP from its debt brake, and NATO allies at The Hague summit (June 2025) agreed to spend 5 per cent of GDP on defence and related security by 2035, 3.5 per cent of it on core military needs.
• Economic and technological revival: the Draghi report (September 2024) estimated that the EU needs 750 to 800 billion euros of additional investment a year to close its productivity gap. The EU also hedged against US tariffs: it accepted a 15 per cent US tariff ceiling in July 2025 while diversifying trade, with the EU-Mercosur agreement provisionally applied from 1 May 2026 and the India-EU free trade agreement concluded on 27 January 2026.

Assessment. The jolt has moved defence to the centre of EU policy, but SAFE offers loans rather than common grants, European industry cannot yet replace US air defence, intelligence and logistics, and unanimity rules let Hungary obstruct. Whether strategic autonomy becomes real or remains a hedge within NATO depends on sustained money and political will. For India, a more autonomous and trade-seeking EU has meant a concluded FTA.

ASEAN: Cooperation Through the ASEAN Way

The Association of Southeast Asian Nations was founded in 1967 by Indonesia, Malaysia, the Philippines, Singapore, and Thailand. ASEAN's founding logic was explicitly different from the EU's: rather than deep supranational integration, ASEAN sought to build a stable framework for regional coexistence among states that were profoundly sovereignty-conscious and politically diverse. The ASEAN Way - characterised by consensus decision-making, non-interference in domestic affairs, informality, and an aversion to legally binding enforcement - became the defining norm of the organisation. ASEAN expanded over five decades to ten members, and with the admission of Timor-Leste as the eleventh on 26 October 2025 it now encompasses the whole of Southeast Asia.

ASEAN's achievements are considerable. It transformed Southeast Asia from a theatre of proxy conflicts into a region where differences are managed through dialogue. The Treaty of Amity and Cooperation of 1976 established principles of peaceful coexistence subscribed to by major powers globally. Intra-ASEAN tariffs have been reduced to near zero under the ASEAN Free Trade Area. Most significantly, ASEAN has established itself as the diplomatic hub of Asia-Pacific regional architecture: ASEAN Plus Three, the East Asia Summit, the ASEAN Regional Forum, and the Regional Comprehensive Economic Partnership - the world's largest trading bloc by population, concluded in 2020 - all flow through ASEAN centrality.

Amitav Acharya's concepts of norm localisation and norm subsidiarity provide the most rigorous theoretical account of ASEAN's success. Norm localisation describes how ASEAN members have selectively adapted international norms to fit prior local beliefs rather than accepting them wholesale. Norm subsidiarity describes ASEAN's creation of its own regional norms to protect regional autonomy from external imposition. Together these explain why ASEAN cooperation has been durable despite its resistance to legalistic enforcement. Kishore Mahbubani, in The ASEAN Miracle, emphasises that ASEAN's principles of consultation, non-interference, and consensus have produced regional peace among extraordinarily diverse states, and that it is a mistake to evaluate ASEAN by the standards of European supranationalism.

ASEAN's limitations are real. The consensus requirement and non-interference norm make it incapable of addressing serious political crises: the Myanmar junta's atrocities after the 2021 coup have been met with ASEAN's Five Point Consensus, which the junta has comprehensively ignored without consequence to its membership. Intra-ASEAN trade at approximately twenty-five percent of total trade is far below the EU's sixty percent, and the single market remains far from realised. Great-power competition between the United States and China creates centrifugal pressures as different members align differently, threatening the unity that the consensus principle requires.

ASEAN Plus Three: Record and Limits

ASEAN Plus Three (APT) brings the ASEAN members together with China, Japan and South Korea. Its leaders first met in Kuala Lumpur in December 1997, and the 1997-98 Asian financial crisis, which East Asian governments felt the IMF had mishandled, gave it its purpose: regional defences that would reduce dependence on Washington-based institutions. Japan's 1997 proposal for an Asian Monetary Fund had been dropped after US and IMF opposition, so APT took a more modest path:

• Chiang Mai Initiative (CMI): agreed by APT finance ministers at Chiang Mai in May 2000 as a network of bilateral currency swaps, it was multilateralised (CMIM) in March 2010 as a 120 billion dollar reserve pool, which members agreed in 2012 to double to 240 billion dollars.
• AMRO: the ASEAN+3 Macroeconomic Research Office, set up in Singapore in 2011 and an international organisation since 2016, monitors member economies and would assess any swap request.
• Asian Bond Markets Initiative (2003): develops local-currency bond markets so that Asian savings are invested in the region, backed by a Credit Guarantee and Investment Facility.
• APTERR: the APT Emergency Rice Reserve, agreed in 2011 and in force since 2012, releases earmarked rice stocks after disasters.
• Crisis cooperation: a special APT summit on Covid-19 in April 2020 backed a regional response fund and a reserve of medical supplies.

How successful? APT has institutionalised financial cooperation that did not exist before 1997, and AMRO gives the region its own surveillance capacity. But the CMIM has never been activated. In 2008 South Korea and Singapore turned to swap lines from the US Federal Reserve, and Indonesia sought bilateral support from Japan and China. The larger part of each member's quota can be drawn only alongside an IMF programme, which governments see as stigmatising. Japan-China rivalry, territorial disputes and the shift of attention to the broader East Asia Summit (2005) and RCEP (2020) have confined APT to technical cooperation. Its record supports the view that East Asian regionalism is strongest in functional, low-politics areas and weakest where great-power rivalry intrudes. India, outside APT, was brought into the wider East Asia Summit partly because Japan and others wanted a balance to China.

SAARC: The Unfulfilled Promise of South Asian Integration

The South Asian Association for Regional Cooperation was established in 1985. It represents an almost textbook case of how bilateral political conflict can paralyse regional integration. South Asia is one of the least economically integrated regions in the world: intra-regional trade accounts for only around five percent of members' total trade - compared to sixty percent in the EU and twenty-five percent in ASEAN - a figure that has continued to decline with the deterioration of India-Pakistan relations. SAARC summits have not been held since 2014.

The core problem is structural. India constitutes approximately seventy percent of SAARC's territory, population, and GDP, creating the dynamic of an asymmetric region in which smaller neighbours simultaneously need Indian economic engagement and fear Indian dominance. Pakistan's persistent use of cross-border terrorism as a foreign policy instrument has made substantive India-Pakistan normalisation politically impossible. The South Asian Free Trade Agreement, signed in 2004, has been undermined by massive sensitive lists, non-tariff barriers, and weak implementation. India's response has been to pursue BIMSTEC - linking India, Bangladesh, Sri Lanka, Nepal, Bhutan, Myanmar, and Thailand through the Bay of Bengal - as an alternative architecture that bypasses Pakistan while extending India's strategic footprint into Southeast Asia.

BRICS: Inter-Regional Coalitional Politics

BRICS - originally Brazil, Russia, India, China, and South Africa, expanded to BRICS+ with the admission of Iran, Egypt, Ethiopia, and the UAE in 2024 and Indonesia in January 2025 - represents a different modality of cooperation: a coalition of emerging powers united not by geographic proximity but by shared structural interests in reforming the Western-led global governance architecture. BRICS was motivated by the perception that the IMF, World Bank, and WTO inadequately reflected the interests and growing economic weight of the Global South, and that the G7 excluded major economies from global economic management.

BRICS's concrete achievements include the New Development Bank, providing development finance as an alternative to World Bank conditionality, and the Contingent Reserve Arrangement, a multilateral currency swap mechanism. BRICS summits have coordinated positions on IMF voting share reform, UN Security Council reform, and greater use of non-dollar settlement. The BRICS+ expansion reflects broader ambitions to consolidate Global South collective weight. The coalition remains, however, structurally strained: India-China strategic rivalry creates fundamental tensions, and Russia's invasion of Ukraine has complicated BRICS's claim to represent a normatively coherent alternative to the Western order.

Regionalisation and Globalisation as Complementary Processes

The relationship between regionalisation and globalisation has been a central theoretical debate since the proliferation of regional trade agreements in the 1990s raised the question of whether regional blocs were building blocks or stumbling blocks for the multilateral trading system. The evidence broadly supports the building block thesis. Regional arrangements have reduced barriers to trade and investment, established norms of open markets, created institutional capacity for managing interdependence, and provided frameworks within which states have developed habits of cooperation that facilitate multilateral engagement. The EU, ASEAN, and USMCA have all been consistent advocates for an open multilateral trading system even as they deepen regional integration.

In an era of complex interdependence, governance has become multi-layered: global problems require global solutions, but regional collaboration makes those solutions more feasible and contextually tailored. Rather than a zero-sum competition between global and regional, the emerging paradigm treats regionalisation as a pillar of globalisation - a means by which countries pool sovereignty in manageable circles, build trust, and achieve collective gains that position them to contribute more effectively on the world stage. For India, this means pursuing regional initiatives such as the International Solar Alliance, BIMSTEC connectivity, and RCEP engagement in parallel with multilateral commitments in the WTO, Paris Agreement, and the SDG framework, treating regional and global integration as complementary rather than competing tracks of foreign policy.

NAFTA and its Replacement by the USMCA

The North American Free Trade Agreement, signed on 17 December 1992 and in force from 1 January 1994, created a free trade area of the United States, Canada and Mexico. It was the first major trade pact joining developed economies with a developing one, and regional trade grew from about 300 billion dollars to over a trillion dollars by 2011. Its limitations were:

• Uneven gains: US unions blamed it for lost manufacturing jobs as assembly moved to Mexican maquiladoras, and critics argued that subsidised US maize hurt small Mexican farmers. The Zapatista uprising in Chiapas began on the day it took effect.
• Weak social clauses: labour and environmental standards sat in side agreements (NAALC and NAAEC) that were hard to enforce.
• Investor-state disputes: Chapter 11 let corporations sue governments before private tribunals over regulation.
• Dated rules: it predated the digital economy, and its 62.5 per cent regional content rule for cars let a large share of components come from outside the region.

Donald Trump, who had denounced NAFTA as a disaster for American workers, threatened in 2017 to withdraw, raising fears that the main bloc of North America would unravel. Renegotiation produced the United States-Mexico-Canada Agreement (USMCA), signed in November 2018, revised in December 2019 and in force from 1 July 2020. It answered NAFTA's limits through:

• Stricter rules of origin: 75 per cent regional content for cars, with 40 to 45 per cent made by workers earning at least 16 dollars an hour.
• Enforceable labour rules: labour and environment chapters inside the agreement, Mexican labour law reform and a rapid response mechanism against individual factories that deny workers' rights.
• Market access and new areas: wider access to Canada's dairy market, and chapters on digital trade and intellectual property.
• Limited investor-state disputes: Canada left the mechanism, and US-Mexico claims were narrowed.
• Sunset clause: a 16-year term with a joint review every six years.

The USMCA has proved less stable than NAFTA. In 2025 the Trump administration imposed tariffs on many Canadian and Mexican goods, and at the first joint review on 1 July 2026 the US declined to extend the agreement, so the parties now face annual reviews until it expires in 2036 unless one withdraws earlier. The episode marks a shift from open regionalism towards managed, security-driven trade.

Latin American Regionalism and the US-led Order

Latin American regionalism has long mixed economic integration with a search for autonomy from the United States, from the Andean Pact (1969) to the dependency school's critique of unequal exchange. After the debt crisis and the Washington Consensus reforms of the 1980s and 1990s, and especially during the 'pink tide' of left-wing governments in the 2000s, the region built bodies that stressed sovereignty and alternative development:

• Mercosur: created by the Treaty of Asuncion (1991) between Argentina, Brazil, Paraguay and Uruguay, and a customs union since 1995. Venezuela has been suspended since 2016, and Bolivia became a full member in July 2024. Its trade agreement with the EU has been provisionally applied since 1 May 2026.
• ALBA: founded by Hugo Chavez and Fidel Castro in Havana on 14 December 2004 as a solidarity-based alternative to the US-backed Free Trade Area of the Americas, which collapsed at the Mar del Plata summit in 2005. Venezuelan oil, partly through Petrocaribe (2005), financed it.
• UNASUR: the Union of South American Nations, whose founding treaty was signed in 2008, added a South American Defence Council. Six members suspended participation in 2018 amid divisions over Venezuela and the choice of a secretary-general, and several moved to the rival PROSUR (2019), before Argentina, Brazil and Colombia rejoined in 2023.
• CELAC: founded in Caracas in December 2011 by 33 states of Latin America and the Caribbean, deliberately without the US and Canada, as an alternative to the US-led Organization of American States. It holds dialogues with China through the China-CELAC Forum and with the EU.

Moderate success. These bodies widened the region's diplomatic space, gave Brazil a platform for leadership and opened links to China, the EU and other partners, and Mercosur has proved the most durable. But success has been limited by ideological swings, since each change of government revives or abandons bodies, by weak supranational institutions, by Brazil's reluctance to bear the costs of leadership, by the collapse of Venezuela's oil economy, which hollowed out ALBA (Ecuador left in 2018 and Bolivia was suspended after its 2025 election), and by dependence on commodity exports, increasingly to China. The US seizure of Venezuela's President Nicolas Maduro in Caracas in January 2026 showed how little regional bodies can protect sovereignty against direct US power. India engages the region through a preferential trade agreement with Mercosur, in force since 2009.
