This book provides a thought-provoking critical analysis of the functionality of regional trade regimes in the Global South. It examines four regional trade agreements (RTAs) - the African Continental Free Trade Agreement (AfCFTA), the Association of South East Asian Nations (ASEAN), the Southern Common Market (Mercosur) and the United States-Mexico-Canada Free Trade Agreement (USMCA). Ngangjoh Hodu and Ajibo argue that while there has been immense enthusiasm amongst countries in the Global South to create RTAs, this has not translated into concerted efforts to make the RTAs work as envisaged, resulting in RTAs that are largely lacking in concreteness. In this innovative work, the authors invite international economic lawyers and other stakeholders to reflect on how normative beliefs and interests inform inter-state relations and thereby, the law of regional economic community. In so doing, it argues that the idea of prosperity underpinning RTAs as they currently exist is more of a mirage than reality.
