The United States and China are the two most important states in the international system and are crucial to the evolution of global order. Both recognize each other as vital players in a range of issues of global significance, including the use of force, macroeconomic policy, nonproliferation of nuclear weapons, climate change and financial regulation. In this book, Rosemary Foot and Andrew Walter, both experts in the fields of international relations and the East Asian region, explore the relationship of the two countries to these global order issues since 1945. They ask whether the behaviour of each country is consistent with global order norms, and which domestic and international factors shape this behaviour. They investigate how the bilateral relationship of the United States and China influences the stances that each country takes. This is a sophisticated analysis that adroitly engages the historical, theoretical and policy literature.
