The rapid modernization of the Chinese Navy is a well-documented reality of the post-Cold War world. In two decades, the People's Liberation Army Navy has evolved from a backward force composed of obsolete platforms into a reasonably modern fleet whose growth is significantly shaking the naval balance in East Asia. The rationale behind China's contemporary rise at sea remains, however, difficult to grasp and few people have tried to see how the current structure of the international system has shaped Chinese choices. This book makes sense of Chinese priorities in its naval modernization in a 'robust' offensive realist framework. Drawing on Barry Posen's works on sources of military doctrine, it argues that the orientation of Beijing's choices concerning its naval forces can essentially be explained by China's position as a potential regional hegemon. Yves-Heng Lim highlights how a rising state develops naval power to fulfil its security objectives, a theoretical perspective that goes farther than the sole Chinese case.
