With greater interconnectedness across various fields, the Indo-Pacific region faces greater security challenges including future strategic power competition. States are increasingly engaging in intense strategic activities and strengthening partnerships. The first part of book focuses on the strategic competition between the United States and China in different areas including cyber security, space security, maritime security, emerging technologies, and institutional frameworks. The second part of the book presents the perspectives of different local actors in the regional theatre and the intentions and concepts behind their growing interconnectedness under Indo-Pacific strategies, including China, Russia, Taiwan, Hong Kong, and North Korea. Through examining different aspects of US–Indo-Pacific strategy, this edited book contributes to a better understanding of Indo-Pacific strategy and its implications for broader security cooperation in a more interconnected world. The book will be of interest to scholars and policy makers working on Asian Security, Politics, International Relations, and the security dynamics of East Asia and the Indo-Pacific.
