Taiwan has said a record number of Chinese military jets flew into its airspace on Monday.
The defence ministry said 25 aircraft including fighters and nuclear-capable bombers entered its so-called air defence identification zone (ADIZ) on Monday.The incursion is the largest in a year and comes as the US warns against an "increasingly aggressive China".
Beijing views Taiwan as a breakaway province.
However, democratic Taiwan sees itself as a sovereign state.
The latest Chinese mission involved 18 fighter jets, as well as four bombers, which can carry nuclear weapons, two anti-submarine aircraft and an early warning aircraft, Taiwan said.
China has carried out regular flights over the international waters between the southern part of Taiwan and the Taiwanese-controlled Pratas Islands in the South China Sea in recent months.
The latest incident came a day after US Secretary of State Antony Blinken said the United States was concerned about China's "increasingly aggressive actions" towards Taiwan.(BBC)
