On March 16 2020 the patrol boats CP-1022 and CP-2006 of the 9th Offshore Flotilla based on Kinmen were attacked by ten Chinese speedboats. They had been assisting a Kinmen County Government Fisheries Research Institute patrol boat in clearing fishing nets illegally left in Taiwanese waters by Chinese fishermen when they came under attack from the men in speedboats throwing rocks and bottles. During the incident CP-1022 was rammed at speed and lost the function of two of their three engines and its hull was damaged. The CGA responded to the attack using less lethal means including stun grenades and bean bag rounds which caused the attacking boats to retreat.
