Multilateralism β cooperation between three or more states through shared institutions and rules β has been the dominant model of international order since 1945. The UN, WTO, IMF, World Bank and EU embody this approach. Since 2016 (Brexit + Trump's first election) and especially since 2020 (COVID + Russia-Ukraine), there are strong signs that multilateralism is in RETREAT β but the picture is more complex than a simple decline.
Evidence that multilateralism IS in retreat.
1. Brexit (2016-2020). The UK voted 52-48 to leave the EU β the world's most successful multilateral organisation. No country had ever left before. Brexit completed in 2020 and represented a deliberate rejection of supranational decision-making.
2. US trade war + unilateralism. Trump's 2018 tariffs on Chinese imports (~370bnat25369bn) and CHIPS Act 2022 ($52bn) are explicit US INDUSTRIAL POLICY β at odds with multilateral free-trade principles.
3. WTO Doha Round collapse. The "Development Round" (2001-15) failed β no major multilateral trade deal has concluded since 1994. New trade is increasingly bilateral (UK-Australia 2021, UK-Japan 2020) or regional (USMCA, CPTPP, AfCFTA).
4. Russia's invasion of Ukraine (Feb 2022). A permanent member of the UN Security Council invaded another country, violating UN Charter and WTO rules. The Security Council was paralysed (Russian veto); the General Assembly condemned but cannot enforce. NATO + EU + G7 responded multilaterally β but the very fact that a Security Council permanent member could invade shows the limits of UN authority.
5. Climate failure. UNFCCC + Paris Agreement cannot keep warming below 1.5Β°C; emissions still rising. Major emitters (USA under Trump 2017-21, China continuing coal, India) prioritise national interest over multilateral commitments.
6. Populism and democratic backlash. Trump (USA), Le Pen (France), AfD (Germany), Brothers of Italy (Italy), PiS (Poland), Bolsonaro (Brazil), Modi (India) all variously question multilateral institutions. UK Brexit; EU friction with Poland + Hungary; US-EU trade frictions all reflect this.
7. Geopolitical fragmentation. The world is fracturing into BLOCS: USA-led (G7 + allies + friendshoring partners); China-led (Belt and Road + BRICS+); Russia-Iran-North Korea axis; EU strategic autonomy. Multilateral institutions struggle to function when major members are at odds.
Evidence that multilateralism is NOT (entirely) in retreat.
1. Some institutions are STRONGER post-2020.
- EU: NextGenerationEU recovery fund (β¬800bn 2020) was unprecedented EU-level borrowing β a major deepening of integration.
- NATO: revived by Russia-Ukraine; Finland (2023) + Sweden (2024) joined; defence spending up.
- G7 + Quad + AUKUS: new or revived multilateral frameworks countering China.
2. Regional multilateralism is expanding. AfCFTA (2021) launched the world's largest free trade area by countries (54 nations). CPTPP added UK in 2024 (12 members). ASEAN + RCEP (2020, 15-country Asia-Pacific bloc including China + Japan + Korea + ASEAN + Australia + NZ) is the world's largest free trade area by GDP.
3. New multilateral initiatives.
- COP27 Loss and Damage Fund (2022) β first multilateral fund for climate-vulnerable nations.
- WHO Pandemic Treaty (2022-26 negotiations) β post-COVID multilateralism.
- UN AI Resolution (2024) β first global AI principles.
- OECD Global Minimum Tax (2021, 140 countries) β coordinated 15% minimum corporate tax.
4. Migration cooperation continues. UN Global Compact for Migration (2018, 152 countries). UNHCR coordinates ~120m displaced people. TΓΌrkiye hosts ~4m Syrian refugees with EU support.
5. Reform of existing institutions.
- IMF quota reform: China + India gained voting share since 2010s.
- World Bank capital increase (2018, 2022).
- G20 elevation over G7 since 2008.
- UNSC reform discussed (though stalled).
6. Trade is still ~58% of global GDP. Despite trade war + plateaus, global trade is at HISTORIC HIGHS. The plumbing of globalisation continues.
Synthesis.
Multilateralism is RESHAPING rather than RETREATING. Two patterns coexist:
Pattern 1: Multilateralism is RETREATING at the GLOBAL level. UN-WTO-IMF-WB system is under strain; major powers (USA, China, Russia) prioritise national or bloc interests; trade is fragmenting; climate is failing.
Pattern 2: Multilateralism is STRENGTHENING at REGIONAL + BLOC level. EU deepening; AfCFTA + CPTPP + RCEP expanding; NATO revival; new technical institutions emerging.
This is the "multi-polar multilateralism" of the 2020s β instead of one global system, several regional + functional systems coexisting. The post-WWII US-led global order is fragmenting; what is being built is a more PLURAL international order.
Applied to specific institutions:
- EU: deepened post-Brexit (NextGenerationEU, Chips Act, Green Deal).
- WTO: weakened (Appellate Body blocked; no new rounds).
- IMF + WB: continuing but contested (BRICS bank as alternative).
- UN: legitimate but constrained (Security Council paralysed on Russia).
- AfCFTA, CPTPP, RCEP: rising.
Judgement.
The statement "multilateralism is in retreat" is HALF-TRUE. Global, UN-system multilateralism IS in trouble. But REGIONAL and FUNCTIONAL multilateralism is THRIVING. The 21st century is unlikely to see a return to mid-20th-century US-led unilateral order, nor a collapse into pure nationalism. The path is a NEGOTIATED MULTI-POLAR order in which the EU, China, India, USA, ASEAN + others coexist as significant players, with institutions adapted to that reality.
For the Pearson 4GE1 syllabus, the key recognition is that GLOBALISATION + INSTITUTIONS coexist with REGIONAL + NATIONAL responses. The story is not retreat OR continuation β it is RESHAPING. A 21st-century answer must capture this nuance.
Conclusion. Multilateralism in its 20th-century form (US-led, UN-WTO-IMF-WB centric, hyper-globalisation) is fading. But multilateralism in NEW forms (regional blocs, functional cooperation, technical institutions, climate frameworks) is emerging. The future is multi-polar multilateralism β neither fully retreating nor fully recovering, but ADAPTING to the realities of the 21st century.
