The Future of Multilateral Cooperation

Three Futures

The multilateral order could evolve in several directions. The first is reformed multilateralism: the existing institutions adapt, with expanded Security Council membership, rebalanced IMF quotas, and new bodies for new challenges. This is the future that most Western governments and the UN Secretary-General advocate.

The second is competitive multilateralism: parallel institutions emerge — Western-led and China/BRICS-led — each with different rules, standards, and membership. States choose between them or participate in both. This resembles the Cold War's institutional landscape and is already materializing in development finance and space governance.

The third is multipolarity without multilateralism: great powers operate through bilateral deals, minilateral clubs, and spheres of influence. Universal institutions continue to exist but become forums for rhetoric rather than action. This is the most pessimistic scenario and the one that most resembles the pre-1914 international order.

Emerging Models

New forms of international cooperation are emerging alongside traditional institutions. Minilateral groupings like the QUAD (US, India, Japan, Australia), AUKUS (US, UK, Australia), and I2U2 (India, Israel, UAE, US) bring together small groups of like-minded states for specific purposes. They are faster and more flexible than universal institutions, but they exclude most of the world.

Multi-stakeholder governance involves non-state actors — corporations, NGOs, scientific bodies, and civil society — alongside governments. The Internet governance model (ICANN, the Internet Engineering Task Force) is an example. The Paris Agreement's inclusion of subnational actors (cities, states, companies) reflects this trend. Whether multi-stakeholder models can scale to address security challenges is uncertain.

Network diplomacy sees institutions less as hierarchical organizations and more as platforms that connect diverse actors. The Commonwealth, the World Economic Forum, and various G-plus formats operate this way. They have influence without authority — valuable but limited.

What to Watch

The trajectory of multilateralism depends on several pivotal factors. First, whether the UN Security Council undergoes any reform before its legitimacy erodes beyond recovery. Second, whether the US and China find areas of institutional cooperation (climate, health, AI safety) even as they compete strategically. Third, whether BRICS develops real institutional capacity or remains primarily a political platform. Fourth, whether the WTO's dispute settlement system is restored.

The deeper question is normative: do states still believe that rules-based international cooperation serves their interests? If they do — even imperfectly — institutions will adapt. If they do not, the twenty-first century will be governed by power rather than rules, and the consequences will be felt by everyone, but most acutely by the smallest and most vulnerable nations that depend on multilateral institutions for their voice and their survival.
