Maritime law enforcement agencies in China

China used to operate several separate maritime law enforcement agencies. These services operated ships as well as their own small aviation units to assist their maritime patrol capabilities. These agencies were often referred to as the "Five Dragons". In March 2013, China announced it would form a unified Coast Guard commanded by the State Oceanic Administration. The new Coast Guard has been in operation since July 2013.
