This book considers the evolving relationship between China and the international system, and the interaction between a China of profound change in its identity, capability, and influence, and an international system that is itself experiencing a process of far-reaching transformation. It develops an analytical framework that allows us to capture, understand and explain a more dynamic pattern of agent-structure interaction in China’s relationship with the international system. By demonstrating a more dynamic and mutually constitutive relationship between China and the international system, the book explores the extent to which both transform themselves in the process, and provides a fuller and more effective assessment of the evolving nature of the relationship. In doing so, it addresses key issues in the current literature on the relationship of China and the international system, and helps close the gap in our knowledge of the conditions and consequences of change and stability in the international system as a result of the change in distributions of power, capability and influence among nation-states.
