Book excerpt: The relationship between Taiwan and the People's Republic of China is regarded as a very serious potential source of conflict in East Asia, especially now that the questions of Hong Kong and Macau have been settled, and increased democratisation in Taiwan is seen as a threat by mainland China. This book, which brings together leading international scholars of maritime security and also strategic thinkers from within Taiwan itself, examines a wide range of questions concerning Taiwan's perception of the naval threat from mainland China, and how Taiwan's navy and naval strategic thinking is responding, including discussions of the strength of Taiwan's naval forces, mainland China's claims and ambitions in the South China Sea, and the controversial question of Theatre Missile Defence.
