This book examines the future of the Asia Pacific’s political economy and its security challenges for the next quarter century. Featuring pertinent discussions on topics such as the ongoing Sino-American power transition and hedging behavior by various states in this vital region, it explains that while some important legacies will endure (such as China’s centrality in the region and continuing U.S. military dominance), other ongoing changes (such as the obsolescence of the Yoshida Doctrine and China’s displacement of the U.S. as the main economic partner for practically all countries in this region) suggest a more turbulent and unpredictable future. The book also explores the profound changes occurring in Chinese, Japanese, and U.S. domestic politics and their cascading effects on the rest of the region. Highlighting how existing Western analytic categories are unable to fully capture the nuances of the Asia Pacific, this book will be a valuable resource to students and scholars of international relations and comparative politics interested in this region.
