Taiwan reported a large incursion by Chinese warplanes for the second straight day.
Taiwan’s defence ministry said eight Chinese bomber planes capable of carrying nuclear weapons, four fighter jets and one anti-submarine aircraft entered its self-declared south-western air defence identification zone on Saturday.
On Sunday 12 fighters, two anti-submarine aircraft and a reconnaissance plane violated its space, Taiwan’s defence ministry said.
On both occasions, Taiwan’s air force warned away the aircraft and deployed air defence missile systems to monitor the planes.
Analysts say China is testing the level of support of newly sworn-in US President Joe Biden for Taiwan.
In the US’s first public remarks on Taiwan since Mr Biden came into power, the US State Department reaffirmed its “rock-solid commitment” to helping it defend itself.
The Trump administration established closer ties with Taipei, ramping up arms sales and sending senior officials to the territory despite fierce warnings from China.
