The Association of Southeast Asian Nations (ASEAN) has become one of the most important players in the global trading system. Comprising 10 countries with very diverse income levels, ASEAN is now the world’s fifth largest economy and plays a central role in the so-called “Factory Asia”. This document begins with an overview of the history and institutions of ASEAN, before focusing on one of its three pillars: the ASEAN Economic Community (AEC), including a critical assessment of outcomes in the areas of trade in goods, trade in services and investment, among others. The document draws best practices from the experience of ASEAN that may be relevant to other regional arrangements pursuing similar goals, and concludes by considering aspects of importance to Latin America’s ongoing economic integration initiatives.
