The idea of regional trade agreements like ASEAN, the AfCFTA, MERCOSUR and even the USMCA as useful linchpins for development and prosperity is driven by globalisation. Most of these fragmented trade regimes that have emerged in the later part of the twentieth and the early twenty-first century have been informed by the discourse on globalisation and the connectivity of international economic order. Therefore, this chapter explores the linkages between the concept of globalisation and regional trade agreements. These linkages are explored to provide some contexts in the second part of the book on how the idea of prosperity as a fundamental rationale behind RTAs in the Global South is more of a myth than reality. It further analyses the evolving discourse on the nexus between regional integration and prosperity to better improve existing and future RTAs to the benefit of its constituent members.
