This paper offers a critical reflection on the potential of solidarity-based and collective South-South cooperation to serve as an
alternative paradigm for “building back better” in the aftermath of cascading global crises. Departing from dominant recovery
frameworks that privilege market-led solutions and external financing, the study foregrounds long-standing regional practices of
mutual aid, technology sharing, and pooled procurement that have historically animated South-South relations. Drawing on archival
analysis, key-informant interviews, and comparative case studies from the Caribbean Community (CARICOM), the South Asian
Association for Regional Cooperation (SAARC), and the Southern African Development Community (SADC), we trace how principles
of solidarity, non-reciprocity, and collective self-reliance have been operationalised during pandemics, debt distress, and climate
disasters. The findings reveal four recurrent mechanisms—diagnostic solidarity (joint epidemiological and risk mapping), fiscal
solidarity (liquidity and debt-service pooling), productive solidarity (distributed manufacturing and technology transfer), and
ecological solidarity (shared adaptation infrastructures)—that enabled faster, more equitable recovery trajectories than those

observed under orthodox conditional lending. Yet the research also uncovers structural limits: asymmetric power relations among
states, donor co-optation of solidarity language, and the erosion of regional policy space through extra-regional trade agreements.
The paper concludes by proposing a praxis-oriented framework that recenters collective regional sovereignty, safeguards solidarity
mechanisms from market capture, and embeds redistributive justice as a non-negotiable pillar of any “better” post-crisis future.
