This paper investigates the patterns, performance, and policy implications of intra-regional trade within two significant regional blocs: the African Union (AU) and the Gulf Cooperation Council (GCC). Employing a comparative and quantitative analysis using gravity models of trade, we assess the impact of economic integration policies on intra-regional trade flows between 2005 and 2022. Results show that while both regions have made significant strides in institutional cooperation, trade intensity remains low, especially in Africa. However, the African Continental Free Trade Area (AfCFTA) represents a major potential game-changer. The study contributes to understanding regional integration dynamics in developing economies and offers targeted policy recommendations to enhance trade complementarities, logistics, and institutional capacity.
