Coast Guard Administration (Taiwan)

The Coast Guard Administration of the Ocean Affairs Council (CGA), also operating as the ROC Coast Guard, is charged with maintaining law and order; protecting the resources of the territorial waters of the Republic of China (Taiwan), which surround Taiwan, Penghu, Kinmen, Matsu Islands, Green Island, Orchid Island, Pratas Island (Tungsha/Dongsha), and Nansha Islands; as well as providing a first line of defense along coastal areas against smugglers and illegal immigrants. The CGA is considered a civilian law enforcement agency under the administration of the Ocean Affairs Council of the Executive Yuan, though during emergencies it may be incorporated as part of the Republic of China Armed Forces.
