The early twenty-first century has seen the beginning of a considerable shift in the global balance of power. Major international governance challenges can no longer be addressed without the ongoing co-operation of the large countries of the global South. Brazil, Russia, India, China, South Africa, the ASEAN states and Mexico wield great influence in the macro-economic foundations upon which rest the global political economy and institutional architecture. It remains to be seen how the size of the emerging powers translates into the ability to shape the international system to their own will. In this book, leading international relations experts examine the positions and roles of key emerging countries in the potential transformation of the G8 and the prospects for their deeper engagement in international governance. The essays consider a number of overlapping perspectives on the G8 Heiligendamm Process, a co-operation agreement that originated from the 2007 summit, and offer an in-depth look at the challenges and promises presented by the rise of the emerging powers.
