All three drones later flew back to the Chinese mainland, according to the Defense Command. Kinmen County is administered by the self-governing island of Taiwan, which Beijing considers its own territory despite never having control over it.
It is not known who operated the unidentified drones.
On Tuesday, Taiwan’s President Tsai Ing-wen said during a troop inspection that she had ordered the island’s defense ministry to take “necessary and decisive countermeasures as needed” against what she called Chinese “gray zone” tactics, including “drones.”
“We will not give China a reason to create a conflict. We will not provoke controversy and we will be restrained, but that does not mean that we will not oppose,” Cai said.
The Chinese government has not yet commented on the incident. However, on Monday, a Chinese foreign ministry official was asked about previous reports of private drone flights in the area, and he replied: “I saw the video too. Chinese drones are flying over Chinese territory – why be surprised?”
Kinmen County is made up of several islands and islets between the mainland coastal Chinese city of Xiamen and the main island of Taiwan.
