Hello aspirants,
Today’s revision capsule of PSIR optional preparation covers Regionalization of World Politics .There are one 20-markers, fourteen 15-markers, and two 10-markers from this topic in the last 12 years.
- Why this matters now
From the supply‑chain shocks of the COVID‑19 years to Russia’s 2022 invasion of Ukraine and the weaponisation of tariffs & chips, states are hedging against a volatile global marketplace by deepening regional ties. 2024‑25 has therefore seen:
- the African Continental FTA’s (AfCFTA) first guided‑trade shipments and a $3.4 trillion common market ambition
- BRICS enlargement (Egypt, Ethiopia, Iran, Saudi Arabia, UAE joined on 1 Jan 2024) to challenge G‑7 weight
- renewed EU–NATO synchronisation after two years of war on its eastern flank, and an internal debate on “strategic autonomy”.
Why Regions Matter in 2025
| Driver | Current Examples | Key Scholars / Concepts |
| Economic scale & resilience | US MCA’s $1.8 tn trilateral trade (2023) ; AfCFTA covering > 1.4 bn people; RCEP’s tariff cuts | Mattli’s demand & supply theory; “open regionalism” (Bergsten) |
| Peace & security | EU kept intra‑European war at bay since 1957*; ASEAN’s TAC & habit of consultation | Deutsch’s security community; Buzan‑Wæver regional security complexes |
| Identity & legitimacy | Timor‑Leste’s fast‑track into ASEAN to “belong”; Pan‑Africanism behind AU | Acharya’s norm‑localisation & subsidiarity; Constructivist takes |
| Geopolitical leverage | BRICS+ expansion (Saudi, UAE, Iran, Egypt, Ethiopia in 2024) ; IPEF used by the US to shape Indo‑Pacific rules | Hurrell’s inter‑regionalism; Nye’s “complex interdependence” |
Note: Regionalization is therefore no longer a side‑show to globalization; it is one of its pillars.
*except 1974 ( Cyprus-Greece-Turkey) clashes and 1999 UK participation in MATO strikes on Yogoslavia.
- Key vocabulary
| Term | Short definition | Typical example |
| Region | Contiguous group of states with shared interdependence | “Indo‑Pacific” or “Southern Cone” |
| Regionalism | Ideology or political project that pushes cooperation | Pan‑Arabism, EU federalists |
| Regionalization | Process (top‑down or bottom‑up) that creates dense cross‑border flows | Intra‑ASEAN supply chains |
| Regional integration | Institutionalised deepening (FTA → customs union → common market → monetary/ political union) | EU’s progression 1951‑2024 |
- Why states integrate (2020‑25 examples)
| Driver | 2025 illustration |
| Economic scale & diversification | USMCA trade hit US $1.8 tn in 2023 |
| Security & conflict prevention | No EU member has fought another since 1945 (Nobel Prize 2012) |
| Connectivity corridors | ASEAN‑led BIMP–EAGA and BIMSTEC grids knit South/South‑East Asia |
| Collective agency | CARICOM’s single voice amplified SIDS demands at COP‑28 (UAE) |
| Geo‑political hedging | AfCFTA & BRICS+ dilute over‑dependence on USA/China dominated regimes |
- Theoretical lenses (then & now)
- Region / Regionalization / Regionalism – now widely include digital (data‑governance clubs) and green (EU CBAM, ASEAN Taxonomy) dimensions.
- Old New Regionalism – first wave (1945‑1990) security‑driven, often protectionist; second wave (post‑1990) market‑friendly, multi‑actor & overlapping (Hettne & Soderbaum).
- Deep Shallow Integration – EU‑style supranationalism v. ASEAN’s loose “ASEAN Way”.
- Spill‑over logic (Haas) still visible—e.g., EU’s single market → Banking Union; US MCA’s auto rules → electric‑vehicle supply‑chain talks.
| School | Core claim |
| Neofunctionalism (Ernst Haas) – spill‑over from one sector to others | EU Banking Union born from Euro‑crisis spill‑over |
| Security‑community (Karl Deutsch) | Dense transactions → war becomes “unthinkable” (EU, Nordics) |
| New Regionalism (Hettne) – multi‑actor, open, overlapping | CPTPP & RCEP memberships criss‑cross |
| Norm localisation / subsidiarity (Amitav Acharya) | ASEAN adapts liberal norms to “Asia‑centric” practice (Five‑Point Consensus on Myanmar shows both reach & limits) |
- Comparison of major blocs ( with mid‑2025 update )
| Bloc | Integration Level | 2025 Highlights | Existing Frictions |
| European Union (27) | Customs‑union, single‑market, partial fiscal & defence coop. GDP ≈ $18 tn | – Ukraine & Moldova accession talks formally opened (June 2024). – Green Deal Industrial Plan accelerates net‑zero supply chains. – First joint ammo procurement for Ukraine shows embryonic defence union. | Brexit after‑shocks; rule‑of‑law rows with Hungary; demographic ageing; farmer protests on Mercosur‑EU FTA |
| US‑Mexico‑Canada (US MCA) | Modern FTA with digital, labour & 6‑/16‑yr review clause | – Merchandise + services trade ≈ $1.8 tn 2023, highest ever. – First rapid‑response labour cases filed against Mexican plants. – Joint review due 2026 spurs talks on critical minerals & EVs. | Auto rules‑of‑origin disputes; US election cycle protectionism; migration pressures outside the pact’s scope |
| ASEAN‑10 (+ Timor‑Leste in accession) | Free‑trade area, blueprint for Economic–Political–Socio‑Cultural communities | – ASEAN GDP passes $4 tn (IMF, 2025) . – Timor‑Leste roadmap to full membership by end‑2025 . – ASEAN Digital Economy Framework negotiations launched 2023. | Myanmar coup stalemate; non‑tariff barriers keep intra‑trade ≈ 25%; navigating US‑China rivalry |
| MERCOSUR (Argentina, Brazil, Paraguay, Uruguay + Bolivia 2024) | Customs union, limited policy coordination | – Bolivia became full member July 2024, giving bloc Pacific access. – Technical terms of EU‑MERCOSUR deal done 2019, but ratification frozen amid EU farm & Amazon concerns. | Intra‑trade < 12%; Uruguay pushes solo FTA with China; macro‑volatility |
| CARICOM (15) | Common Market & Economy (CSME) in slow‑motion | – Agreed Single ICT Space (2024) & mutual recognition of additional professional categories. – Joint climate‑finance lobby secured loss‑and‑damage funding pledges at COP‑28. | Economic asymmetry; migration (“brain drain”); fiscal space for regional bodies |
| BRICS → BRICS+ (10) | Loose inter‑regional coalition; NDB financing | – New members from West Asia & Africa join Jan 2024; bloc now ~45 % of world population. – Talks on cross‑border payment platform using local currencies. | Internal geopolitical rifts (India‑China); varying economic outlooks |
| IPEF (14 Asia‑Pacific members) | “Menu‑of‑pillars” framework, no tariffs | – Supply‑Chain Agreement entered into force Feb 2024; Clean‑Economy & Fair‑Economy texts signed but await ratification. | Critics call it “TPP‑lite” without market‑access carrot; China’s exclusion |
- Key lessons across cases
- Depth vs breadth trade‑off – EU’s supranational reach delivers single‑currency clout but suffers from veto politics; ASEAN’s consensus model preserves unity but slows crisis response.
- Hegemonic reassurance matters – USMCA works because rules help keep U.S. market access and constrain its unilateralism; SAARC falters where India‑Pakistan rivalry persists.
- Issue‑linkage drives resilience – blocs that move beyond tariffs to climate, digital and health (EU, AU, Pacific Islands Forum) adapt better to 21st‑century shocks.
- Open regionalism avoids “fortress” critique – RCEP’s WTO‑plus rules and AfCFTA’s coordination with global norms show complementarity, not conflict, with multilateralism.
- India’s multi‑layered appraoch
- Neighbourhood‑first: From SAARC stalemate to BIMSTEC energy grid and BBIN motor‑vehicle pact.
- Act East: Comprehensive Economic Cooperation Agreements with ASEAN members (Singapore, Malaysia, etc.) feed into IPEF supply‑chain pillar with US, Japan, Australia.
- South‑South leadership: BRICS presidency 2026 will let India steer reform of global financial architecture and push Digital Public Infrastructure project.
- Indo‑Pacific Minilaterals – QUAD & I2U2 complement formal regionalism with security‑tech agendas.
- Regionalization & Globalization – a symbiotic future
Global shocks require nested governance:
| Layer | Example post‑2022 action |
| Global | G‑20 debt‑relief framework; WTO e‑commerce talks |
| Inter‑regional | BRICS Vaccine R&D hub; Quad critical‑minerals partnership |
| Regional | EU REPowerEU (energy); ASEAN Pandemic Fund |
| Sub‑regional / corridors | IMEC (India‑Middle‑East‑Europe Corridor); BRI economic belts |
- Synthesis and Concluding remarks
The trend is towards a multiplex order: overlapping circles where states hedge, leverage and sometimes leapfrog global deadlock via tighter neighbourhood coalitions.
- Layered governance is today’s norm: states try to manage different global institutions, region‑wide treaties, and purpose‑built minilaterals.
- Open, overlapping regionalism usually adds to – not crowds out – globalization by piloting rules (digital, green, labour) that later scale up.
- Quality of institutions matters more than geography: SAARC’s inertia compared with ASEAN’s adaptable norms; EU shows depth costs political capital.
- Future fault‑lines: managing just transitions (farmers, miners), aligning industrial policy (subsidies war), and bridging Global North‑South financing gaps.
