TAIPEI, Sept 1 (Reuters) - Taiwan's military for the first time shot down an unidentified civilian drone that entered its airspace near an islet off the Chinese coast on Thursday, after the government vowed to take tough measures to deal with an increase in such intrusions.
Beijing, which claims Taiwan as its own against the strong objections of the Taipei government, has held military exercises around the island since early last month in reaction to a visit to Taipei by U.S. House of Representatives Speaker Nancy Pelosi.
Taiwan's government has said it will not provoke or escalate tensions but has been particularly angered recently by repeated cases of Chinese drones buzzing islands controlled by Taiwan close to China's coast.
The defence command for Kinmen, a group of Taiwan-controlled islands opposite China's Xiamen and Quanzhou cities, said in a statement released by Taiwan's defence ministry that the drone entered restricted air space over Lion Islet just after midday (0400 GMT).
Troops on the islet tried warning it away but to no effect, so shot it down, with the remains landing in the sea, it added.
Taiwan fired warning shots at a drone for the first time on Tuesday shortly after President Tsai Ing-wen ordered the military to take "strong countermeasures" against what she termed Chinese provocations.
China's foreign ministry, which on Monday dismissed Taiwan's complaints about drones as nothing "to make a fuss about", referred questions to the defence ministry, which had yet to comment.
Chiu Chui-cheng, deputy head of Taiwan's China-policy making Mainland Affairs Council, told reporters in Taipei that Taiwan had the legal authority to take "necessary defence measures", as Chinese aircraft were not allowed into Kinmen's air space.
Those measures include forcing aircraft to leave or to land, he said.
Speaking to the armed forces earlier on Thursday, Tsai said China was using drones and other "grey zone" tactics to try to intimidate Taiwan, her office cited her as saying in a statement.
Tsai again emphasised that Taiwan would not provoke disputes but that did not mean that it would not take countermeasures, the statement added.
"She has also ordered the Ministry of National Defense to take necessary and strong countermeasures in a timely manner to defend national security," it said.
"Let the military guard the country without fear and with solid confidence."
Taiwan has controlled Kinmen, which at its closest point is a few hundred metres (feet) from Chinese territory, since the defeated Republic of China government fled to Taipei after losing a civil war to Mao Zedong's communists in 1949.
During the height of the Cold War, China regularly shelled Kinmen and other Taiwanese-held islands along the Chinese coast, but they are now tourist destinations.
