Chapters on economic cooperation are increasingly evident in trade agreements. The principles are clear but the mechanics are not. This paper presents a case study of a relevant project linked to the IA-CEPA which focuses on impediments to trade associated with differences in regulatory systems. It explains the procedures adopted and identifies a number of outcomes. Implications are identified for the design offuture projects relevant to cooperation chapters, and for the application of concepts discussed elsewhere in the literature that are relevant for reducing impediments to trade in the context of global value chains.
