In this book, perhaps his most ambitious so far, Cooper brings together a lifetime of work on global governance, diplomacy, and summitry, into a grand synthesis on one of the most significant, yet most neglected phenomena in international relations. The Concertation Impulse in World Politics constitutes a major theoretical breakthrough, conceptualizing the emergence of an alternative to traditional IOs as key entities in the new century. Cooper does justice to the role groups like the G7, the G20 and the BRICS play in a rapidly changing international system, capturing their unique features and dynamics, and providing fresh insights into our troubled and crisis-prone world.
