The paper focuses on the factors that determine the supply of RPGs as a way to better understand these implementation gaps, moving away from uniform thinking about regional cooperation and towards one that is more adaptive and “problem driven.” The characteristics of the different aggregator technologies—a key co-determinant along with political incentives of the availability of any RPG—are then illustrated with examples (e.g. “weakest link” for regional corridors). The RPG characteristics of the 15 flagships of the AU2063 programme are briefly presented and discussed with comments.
