After the Cold War, International Relations has seen a resurgence of interest in the study of regional powers. Scholars have been paying increasing attention to regional powers as important actors in world politics and studying their foreign policy, but few if any studies have discussed the behaviors of regional power comprehensively and comparatively. The purpose of this book is to gain a better understanding of regional power foreign policy strategies and behaviors by analyzing them comprehensively and comparatively. Unlike previous studies on cooperation and conflict within regions, this study focuses on the reasons for the strategic tendencies and motivations of regional hegemons and great powers and their effects on regional cooperation and conflict. Moreover, departing from Hegemonic Stability Theory, this book also aims to explore similarities and differences between regional and global hegemonic foreign policy strategies.
