Book excerpt: We assume that the ideas, interests and strategies of regional powers are highly significant variables, with the power to influence foreign policy. Yet while comparative research projects involving OECD-countries are fairly common, comparative research integrating developing regions is still rare, despite the fact that these countries are among the key actors of the twenty-first century. This collection emphasizes the role of regional powers in intra-regional, interregional and global contexts, analyzing the rise of regional powers from a comparative perspective. In so doing, the book explains how these powers have power to shape regional and global politics.
