TAIPEI (Taiwan News) — The defense ministry detected 14 Chinese aircraft, nine naval ships and one official government vessel between 6 a.m. on Friday and Saturday.

Nine of the aircraft reportedly crossed the median line of the Taiwan Strait and entered the nation’s northern and eastern air defense identification zone, or ADIZ. In response, Taiwan sent aircraft and naval ships and deployed coastal-based missile systems to monitor Chinese activity.

So far this month, Taiwan has tracked Chinese military aircraft 211 times and ships 90 times. Since September 2020, China has continued its use of gray zone tactics by incrementally increasing the number of military aircraft and naval vessels operating around Taiwan. 

CSIS defines gray zone tactics as “an effort or series of efforts beyond steady-state deterrence and assurance that attempts to achieve one’s security objectives without resort to direct and sizable use of force.”
