The history of Taiwan's Coast Guard Administration can be traced back to several origins. One of these is the former 7th Special Police Corps, which was expanded from the late and unique River Patrol squadron of the Taipei County (now New Taipei City) Police Department. The land branches of Coast Guard Administration originate from the controversial Taiwan Garrison Command, which no longer exists, but the formations of land patrol forces were inherited from the ROC Army. Because of its interesting and complicated origins, the Coast Guard Administration does not always go along well with the police, especially when problems related to legal jurisdiction on land occur.
