China claims democratic Taiwan as part of its territory and says it will never renounce the use of force to bring it under Beijing's control.

In a statement Monday, Taiwan's defence ministry said 10 Chinese aircraft crossed the Air Defence Identification Zone (ADIZ) in the past 24 hours, and that it had responded appropriately.

Last Thursday Chinese warships and fighter jets encircled Taiwan in drills that Beijing said were a test of its ability to seize the island.

During the two-day drills, China vowed that "independence forces" would be left "with their heads broken and blood flowing".

Beijing has in recent years upped military pressure on Taiwan, maintaining a near-daily presence of warplanes, drones and naval vessels around the island.

Experts say these are "grey zone tactics", which stop short of outright acts of war but serve to exhaust Taipei's military.

Taiwan's new president said Sunday he was still ready to work with China, despite the military drills.

China said Lai Ching-te's inaugural speech on Monday last week amounted to calls for independence, "pushing our compatriots in Taiwan into a perilous situation of war and danger".
