Non-traditional security has been a catch word after the 9/11 terrorist attack. Also it becomes a main concern of the international community as non-traditional security threats will for sure endanger world peace and security. Although there is no accurate definition on “non-traditional security issues”, the issues usually refer to those emerging and new issues concerning security such as terrorism, sea piracy, human trafficking, mass pollution, epidemics, etc. While there is abundant literature discussing non-traditional security issues in various ways and on various topics, there is little mention of such issues existing in the South China Sea. In order to fill the gap, this edited volume has accommodated contributing papers with high quality from well-known scholars around the worldwide academic community.
