The question of how the United States should respond to China's military modernisation effort, including its naval modernisation effort, has emerged as a key issue in U.S. defence planning. The issue is of particular importance to the U.S. Navy, because many U.S. military programs for countering improved Chinese military forces would fall within the Navy's budget. Decisions that Congress and the executive branch make regarding U.S. Navy programs for countering improved Chinese maritime military capabilities could affect the likelihood or possible outcome of a potential U.S.-Chinese military conflict in the Pacific over Taiwan or some other issue. This book examines the background, implications and other issues for the United States concerning China's naval modernisation.
