Japan Coast Guard and Coast Guard Administration (Taiwan) during a territorial dispute near the
Senkaku Islands in 2012 exercise The CGA was established on 1 February 2000, combining the Coast Guard Command (formerly under the Ministry of Defense), the Marine Police Bureau (formerly under the
National Police Administration, Ministry of Interior), and several cutters from the Taiwan Directorate General of Customs, Ministry of Finance. The CGA formally unifies coastal and maritime law enforcement agencies. It has seen a great deal of action for a young agency, participating in numerous
search and rescue and anti-smuggling operations. The Coast Guard Administration was also recently involved in escorting Taiwanese fishing boats into waters disputed with Japan claimed by both sides as part of their exclusive economic zones. The Coast Guard Administration had to expand rapidly to meet the rising grey-zone challenge. In May 2019 the CGA detained two Chinese fishing vessels for illegally fishing inside Taiwan's territorial waters. One vessel was 0.4 nautical miles off Taiwanese shores while the other was 2.1 nautical miles offshore. In May 2019 the CGA rescued six fishermen aboard a burning boat nineteen miles offshore. Five fisherman were picked up by cutter while the most seriously injured was airlifted to hospital by helicopter. All fishermen survived the ordeal although three required hospitalization. As of 2019 the CGA planned to construct a total of 141 ships, including four 4000-tonne, six 1000-tonne, 12 600-tonne, 17 100-tonne, 52 35-tonne patrol ships and 50 coastal multi-purposed ships, by 2027. The CGA responded to the attack using less lethal means including
stun grenades and
bean bag rounds which caused the attacking boats to retreat. In July 2020 the CGA arrested all 18 crew members of a Chinese fishing vessel caught fishing illegally in Taiwanese waters. The interdiction followed an increase in illegal fishing in Taiwanese waters by Chinese fishing vessels. Between January and July 2020 the CGA chased 2,988 Chinese
sand dredging vessels out of Taiwanese waters. In July 2020 the CGA seized a dredging vessel and arrested its eight crew as a warning to the rest. In August 2020 the CGA detained a small Chinese
oil tanker which had illegally entered Taiwan's waters. The oil tanker was discovered during enhanced COVID-19 pandemic biosecurity patrols. In May 2021 the CGA detained a Chinese offshore supply vessel and its 12 crew. The vessel was caught trespassing in Taiwanese waters near
Penghu. It is believed that the supply ship was being used to deliver food and other supplies to offshore fishing fleets. In 2021 the Taiwanese cabinet approved a NT$12.9 billion (US$428.53 million) budget for six new 3,000-ton class patrol vessels. In May 2022 an Anping-class patrol ship launched a
Hsiung Feng II anti-ship missile for the first time in a joint exercise with the Navy. Following an incident in 2025 which a Chinese owned vessel flying a
flag of convenience damaged an underwater telecommunications cable the CGA increased their monitoring of ships flying flags of convenience and increased the distance from shore at which they would be subject to routine boarding. The captain of the vessel was later convicted on charges related to the incident and sentenced to three years in prison. ==International cooperation==
