Book excerpt: China emerged as a major economic, diplomatic, and military power during the critical decade from 2008 to 2018. As a result, China's foreign policy has become more active and dynamic. This book provides a unique perspective to understand Chinese foreign policy during this decade by examining continuities and changes in both internal and external factors that have shaped China's development. The book focuses on key challenges in China's diplomacy such as US-China relations, the Korean Peninsula, Taiwan, Japan, India, Chinese investment overseas, the Belt and Road Initiative, global and regional cooperation, soft power, etc. It also includes an extensive annotated bibliography of major recent publications on various aspects of Chinese foreign policy. This is the first scholarly book that studies the evolution and key challenges of China's foreign relations during the critical decade (2008-2018) when China grew into a crucial, sometimes assertive, power in international affairs.
