This paper forms part of a broader research project TIPS has been involved in around common regional industrial policies. It looks at three examples of regional integration: the Association of Southeast Asian Nations (ASEAN), the European Union and Mercosur. The focus is on understanding the drivers and motivation for regional integration in different parts of the world. It looks into how integration was supported and directed, and specifically how these blocs deal with issues of common industrial policies. It aims to assist in understanding the supply and demand for deepening regional integration and how integration options and approaches can be designed to respond to highly specific contextual circumstances.
