The Agency of Middle Powers in a Fragmented and Polarised World

The international system is entering a period of intensified fragmentation and geopolitical polarisation. Competition among China, Russia, and the United States is reshaping the global order and redefining spheres of influence. These dynamics create both challenges and opportunities for middle powers, which must navigate contested spaces where alignment with one great power can generate tensions with others.

Middle powers face a delicate balance: they seek to preserve their autonomy, influence multilateral institutions and maintain credibility in international networks, and their choices whether to align with a particular great power, hedge their international relationship bets, or engage in principled diplomacy can either stabilise fragmented regions or amplify systemic competition. Yet debates about the future of the international order tend to focus on great powers and institutional reform, leaving the behaviour of middle powers under-explored.

This Policy Brief examines how middle powers can exercise strategic autonomy and influence in a fragmented world. It emphasises behaviour, relational positioning, and policy choices rather than material capacity alone by analysing how middle powers balance principles with pragmatism; manage geography and alignment; and engage in bridge-building, coalition-building, and mediation. It then assesses their capacity to stabilise regional and global orders, support multilateralism, and enhance systemic resilience.
