# China Marine Surveillance

China Marine Surveillance (CMS; Chinese: 中国海监; pinyin: Zhōngguó Hǎijiān) was a maritime surveillance agency of China.
Patrol vessels from China Marine Surveillance were commonly deployed to locations in the South China Sea and East China Sea where China has territorial disputes over islands with its neighbors. The CMS has played a central role in China's in defending Chinese territories in the South China Sea, encountering opposition from Japan, the Philippines and Vietnam in the disputed territories, as China.
The agency has been disbanded in July 2013 and has now been merged, along with three other similar agencies, with the China Coast Guard.

## Organization and function

Established 1998, the CMS, charged with the supervisory responsibility for some 3 million square kilometers of Chinese declared territorial waters, employs some 7,000 individuals and operates some 10 aircraft, including at least one Mil Mi-8 helicopter and two Harbin Y-12 utility planes, and 400 seagoing vessels.(Two Harbin Y-12 aircraft seen at Guilin airfield on a number of occasions in August 2013.) It has grown in fleet size and capability. Its fleet was made up of, in part, destroyers and other former Chinese Navy vessels.
