Taiwan's shooting down of a drone that buzzed a Taiwanese-controlled island off the Chinese coast was the most "appropriate" thing to do after repeated warnings, and China should exercise restraint, Taiwan Premier Su Tseng-chang said Friday.

Taiwan's military for the first time shot down an unidentified civilian drone that entered its airspace near an islet close to the Chinese city of Xiamen on Thursday, after the government vowed to take tough measures to deal with an increase in such intrusions.

The incident came after Taiwan had repeatedly complained of harassment by drones coming from China and flying right up close to the Kinmen islands, which has been taking place as Beijing stages military drills around Taiwan.
