Middle powers are building coalitions outside the UN framework

The diplomatic landscape is undergoing a structural transformation as middle powers increasingly bypass the United Nations system in favour of flexible coalitions tailored to specific interests. This shift is not merely a response to Security Council gridlock, though that paralysis provides ample motivation. It represents a fundamental recalculation of how states in the second tier of the international hierarchy can maximise their influence in an era when the postwar institutional order no longer commands universal deference.

These minilateral arrangements—groupings of three to a dozen states organised around shared concerns rather than geography or ideology—have multiplied across every region. They allow participants to coordinate on trade, security, or technology without the procedural constraints or ideological litmus tests that formal multilateralism imposes. For countries too small to shape global institutions alone but too significant to accept permanent marginalisation, such coalitions offer a pathway to agency that the UN framework increasingly denies.

The appeal is straightforward. Within the Security Council, middle powers hold no veto and limited agenda-setting authority. Permanent membership remains frozen in the geopolitical configuration of 1945, and efforts at reform have foundered on the resistance of those who benefit from the status quo. For states such as Indonesia, Turkey, or South Africa, participation in UN processes often means endorsing outcomes negotiated by others or registering symbolic dissent that changes nothing. Minilateral groupings invert that dynamic, placing middle powers at the centre of decision-making on issues they select.

The expansion of BRICS illustrates the model's attractions. What began as an acronym for emerging economies has evolved into a platform where middle powers can articulate alternatives to Western-led financial architecture, coordinate diplomatic positions, and signal autonomy from both Washington and Beijing. Membership conveys status without requiring ideological conformity or subordination to a hegemon. The grouping's recent enlargement demonstrates that many states value this flexibility more than the coherence or effectiveness that a smaller, more homogeneous membership might provide.

Regional security dialogues follow a similar logic. Middle powers in the Indo-Pacific, the Gulf, and Latin America have constructed overlapping networks that allow them to address threats without invoking alliance structures dominated by great powers. These arrangements enable participants to hedge: a state can coordinate with the United States on maritime security through one grouping whilst engaging China on infrastructure through another, all without the binary choices that formal alliances typically demand. The result is a diplomatic posture that preserves room for manoeuvre even as geopolitical competition intensifies.

Trade blocs that exclude traditional powers serve comparable purposes. By negotiating agreements among themselves, middle powers can set standards, capture efficiency gains, and reduce dependence on markets in the United States, Europe, or China. Such arrangements also function as bargaining chips: a middle power leading a regional trade initiative commands more attention in bilateral negotiations with a great power than one approaching alone. The proliferation of these blocs reflects not only economic logic but a deliberate strategy to accumulate leverage in a multipolar system.

The shift carries institutional advantages beyond flexibility. Minilateral groupings allow middle powers to claim leadership roles that would be unattainable in universal forums. Hosting a summit, chairing a working group, or brokering a joint statement confers visibility and legitimacy that enhance a state's diplomatic standing. For governments seeking to project influence both domestically and abroad, these opportunities matter. They transform middle powers from rule-takers into rule-shapers, at least within the scope of the coalition.

Yet this proliferation generates risks that proponents of minilateralism often understate. The fragmentation of global governance into overlapping coalitions weakens the normative authority of universal institutions. When states can forum-shop—selecting the venue most likely to endorse their preferences—the notion of a single rules-based order becomes difficult to sustain. Different groupings may adopt conflicting standards on issues from trade to human rights, and no overarching mechanism exists to reconcile them. The result is not multipolarity but a patchwork of competing mini-orders, each with its own logic and membership.

The effectiveness of minilateral groupings also remains uncertain. Flexibility is an asset when building coalitions, but it becomes a liability when implementation requires sustained coordination. Many of these arrangements lack enforcement mechanisms, secretariats, or budgets. Commitments are often aspirational, and follow-through depends on the continued alignment of national interests that may shift with elections or economic conditions. The gap between the rhetoric of partnership and the reality of delivery can be substantial.

There is also the question of whether minilateralism genuinely redistributes power or merely creates new hierarchies. Within many of these groupings, one or two states dominate by virtue of economic size, military capability, or diplomatic resources. Smaller members may find themselves in relationships that replicate the asymmetries they sought to escape, only with different patrons. The risk is that middle powers trade dependence on established powers for dependence on rising ones, without gaining the autonomy they sought.

The proliferation of coalitions also complicates crisis management. In a system where states belong to multiple overlapping groupings with divergent memberships and mandates, coordinating responses to shocks becomes more difficult. The absence of a central forum where all relevant parties are present means that information may not circulate, positions may harden in parallel rather than through negotiation, and opportunities for compromise may be missed. Fragmentation that serves national interests in calm times can prove costly when rapid collective action is required.

Despite these concerns, the momentum behind minilateralism shows no sign of abating. Middle powers have concluded that the transaction costs of working within universal institutions outweigh the benefits, and that flexible coalitions better serve their interests in a multipolar world. This judgement reflects not only frustration with the UN but a broader reassessment of how influence is accumulated and exercised in contemporary international relations. The question is not whether this trend will continue but what kind of order emerges from it.

The strongest counter-argument holds that universal institutions remain indispensable for addressing genuinely global challenges. Climate change, pandemic response, and nuclear non-proliferation require coordination at a scale that minilateral groupings cannot provide. Fragmentation may allow middle powers to maximise their influence on regional or sectoral issues, but it leaves them collectively weaker when confronting threats that respect no borders. From this perspective, the proliferation of coalitions is a form of free-riding: states enjoy the flexibility of minilateralism whilst relying on the stability that universal institutions, however imperfect, continue to provide.

There is force to this objection, yet it understates the degree to which middle powers have lost faith in the willingness of great powers to reform those institutions. Calls for Security Council reform, more equitable representation in international financial bodies, and greater voice in standard-setting processes have been made for decades with little result. In the absence of meaningful change, middle powers have pursued alternative strategies. Whether those strategies ultimately strengthen or undermine the broader international order depends on choices not yet made.

The architecture that emerges will likely be hybrid rather than binary. Universal institutions will persist, their legitimacy eroded but their functions still necessary. Alongside them, a dense network of minilateral groupings will continue to proliferate, some ephemeral and others durable. The challenge for policymakers is to manage the interface between these two layers: to preserve the normative authority of universal rules whilst accommodating the legitimate demand of middle powers for greater agency. That balance has not yet been struck.

What remains genuinely at stake is whether the fragmentation of global governance will prove creative or destructive. If minilateral coalitions serve as laboratories for new approaches that eventually feed back into universal institutions, they may revitalise multilateralism rather than replace it. If instead they harden into rival blocs with incompatible standards and interests, the prospect of coordinated action on shared challenges will recede. Middle powers are betting that they can navigate this tension, but the outcome will depend as much on the choices of great powers as on their own.
