US–China strategic competition is quickly becoming the key factor for determining the future of Indo-Pacific regional security and stability. This edited volume seeks to take readers through strategic competition between the United States and China and their rivalry, and the challenges that competition poses for Indo-Pacific strategy and US foreign policy. The first section focuses on exploring the strategic competition in different areas including institutional dilemmas, space power, cyber deterrence, emerging technologies, and maritime security. The second section of the book covers individual cases of China, Russia, Taiwan, Hong Kong, and North Korea and how they may pose challenges for the United States’ Indo-Pacific strategy and foreign policy. Through examining different aspects of the strategic competition, this book contributes to a better understanding of the United States’ Indo-Pacific strategy and its implications for broader security cooperation—‘strategic cooperation’—in a more interconnected world.
