In 2010 the CGA held their first ever drill with China's Maritime Search and Rescue Center. The drill, which simulated a ferry disaster between Kinmen and Xiamen, included 14 vessels, 3 helicopters, and 400 personal. Due to the tense relations between the two countries participating forces used drill flags instead of their national flags and emblems. The second drill in 2012 involved 18 vessels and two helicopters from Taiwan, as well as 11 ships and one helicopter from China. A third drill in 2014 featured 33 vessels, four helicopters, and 550 personnel.
