Multilateralism and the international institutions that have long sustained it—face a deep and multi-layered crisis. While this predicament is widely recognised in International Relations scholarship, existing debates have yet to fully engage with how fragmentation impacts different types of international institutions across geographical and functional domains, particularly through the lens of Global North–Global South dynamics.
Our TWQ Special Issue (Fragmented Multilateralism and International Institutions: Between Complexities and Challenges, Third World Quarterly, Andrew F. Cooper, Emel Parlar Dal, Samiratou Dipama) aims to unpack how different actors— notably ascendant powers like China and India, established actors like the EU and the U.S., or historically overlooked regions such as Latin America—navigate, contest, and reconfigure multilateralism in response to shifting global power constellations.
Rather than treating fragmentation as merely a symptom of institutional decline, the articles collectively suggest that fragmentation itself is a defining feature of the current global order—one that reflects competing visions, asymmetric capabilities, and regionally embedded institutional legacies.
By challenging the notion of a cohesive and universal multilateral order, our TWQ Special Issue calls for a more pluralistic and differentiated theorization of international cooperation—one that recognises both the agency of the Global South and the structural constraints embedded within the global institutional architecture.
Understanding the crisis of multilateralism requires moving beyond formal intergovernmental organisations (FIGOs) to examine the complex interplay of formal and informal institutions across geographical and functional domains.
This special issue points to the missing point in the existing literature about the complex interactions existing between multilateralism and international institutions from a wide range of perspectives in terms of geographical, institutional and issue area scopes.
Multilateralism is no longer solely the domain of formal institutions; informal intergovernmental organisations are increasingly shaping its future in both the Global North and South.
The fragmentation of multilateralism is not merely a recent phenomenon—it is a deep, gradual process that has intensified in the wake of successive global crises.
