In view of its size, and vast land and sea boundaries that it shares with its neighbours, China has always regarded its peripheral policy as a crucial aspect of its national security. Such a mentality conforms to Chinese leaders' core belief that a stable external environment - in particular, its immediate region - remains the sine qua non for the continued and sustained rejuvenation of their nation.This book examines China's evolving strategies towards its surrounding peripheries. It is the first book to examine in detail President Xi Jinping's steering of China's peripheral diplomacy. It argues that China pursues an ambitious, omnidirectional regional diplomacy that emphasizes the entire periphery region, and not just specific peripheries. According to this book, Chinese regional policy cannot be properly and adequately understood without taking into account its full breadth, substance and scope. Featuring chapters that explore China's evolving policy in Northeast Asia, Southeast Asia, South Asia and Central Asia, and addressing new developments under Xi, this book fleshes out the intricacies of how China has been managing its peripheral relationships in Asia under new circumstances and new leadership.
