Maritime security is of vital importance to the South China Sea, a critical sea route for maritime transport of East Asian countries including China. The adjacent countries have rendered overlapping territorial and/or maritime claims in the South China Sea which complicate the situation of maintaining maritime security and developing regional cooperation there. This book focuses on contemporary maritime security in the South China Sea as well as its connected sea area, the Straits of Malacca and Singapore. It identifies and examines selected security issues concerning the safety of navigation, crackdown on transnational crimes including sea piracy and maritime terrorism, and conflict prevention and resolution. In the context of non-traditional security, issues such as maritime environmental security and search and rescue at sea are included. The book explores ways and means of international cooperation in dealing with these maritime security issues.
