Some of the planes flew over an area northeast of Pratas, according to a map provided by the ministry. However, the bombers, accompanied by cyber warfare and a reconnaissance aircraft, flew over the Bashi Canal, which separates Taiwan from the Philippines and the Pacific, before returning to China on the route they took. Taiwan has sent fighter jets to warn Chinese aircraft, while missile systems have been developed to monitor them, the ministry said, using standard wording for its response. It was the largest invasion since Taiwan listed 30 Chinese aircraft in its ADIZ on May 30. The largest to date this year occurred on January 23, with the participation of 39 aircraft. read more There has been no immediate comment from China, which has said in the past that such moves were exercises aimed at protecting the country’s sovereignty. A State Department spokesman told Reuters in an email that Beijing should “stop military, diplomatic and economic pressure and intimidation against Taiwan.” China launched its third aircraft carrier on Friday, the Fujian, named after the province opposite Taiwan. read more The Chinese military said last month it was conducting an exercise around Taiwan as a “responsible warning” against its “collusion” with the United States.

China has stepped up pressure on Taiwan to accept its claims of sovereignty. The Taipei government says it wants peace, but will defend itself in the event of an attack.
