This book analyzes the social forces and political coalitions driving regional integration projects in Asia with a focus on ASEAN and Indonesian conglomerates. It asks which social forces within the domestic political economy of Asian states are driving governments to seek regional arrangements for economic governance. In particular, the book considers how the emergence, reorganization, and expansion of capitalist class have conditioned political support for regional economic integration. By addressing these issues, the book emphasizes that the wellspring of regional economic institution projects stem from the process of capitalist development and the social forces it has unleashed. The book's aims place the social and class relations that underpin regional projects--rather than the institutions which result from them--at the centre of the analysis of regional integration. The research for this account draws mainly on primary documents from archival and field research conducted by the author, including company documents and in-depth interviews, government reports and policies, and trade publications and data sources, which is supplemented with secondary sources where relevant.
