Four J-16s and four JH-7s, along with an electronic warfare aircraft, flew close to the Pratas Islands in the southwestern part its air space. In response to the incursion, Taiwan’s airforce activated its missile system, and issued radio warnings, according to the Defence Ministry. Chinese fighter jets regularly violate Taiwan’s airspace with their incursions.
Beijing says it is responding to what is believes is “collusion” between Taipei and Washington.
Like most countries, the US has no official diplomatic ties with Taiwan, but is the island’s most powerful international backer and supplier of weapons.
The Biden administration has pledged to continue giving “rock solid” support for Taiwan.
In his first telephone call with President Xi Jinping on February 10, US President Joe Biden raised his concern about Beijing’s aggressive stance towards the island nation.
In a statement released by the White House after the call, Mr Biden said: “I spoke today with President Xi to offer good wishes to the Chinese people for lunar new year.
“I also shared concerns about Beijing’s economic practices, human rights abuses, and coercion of Taiwan.”
This includes developing a fleet of new submarines, buying new F-16 fighters from the United States and upgrading its warships.
To oversea the changes, the Taiwanese president has just appointed the former National Security Bureau Director-General Chiu Kuo-cheng as Defence Minister.
Mr Kuo-cheng has close ties with the US, having graduated from the US Army War College in 1999.
