36 Chinese warplanes detected around Taiwan

China claims self-ruled democratic Taiwan as part of its territory and has said it would never renounce the use of force to bring it under Beijing's control.

It has stepped up pressure on Taipei in recent years and held war games around the island following the May 20 inauguration of new Taiwanese leader Lai Ching-te, who Beijing regards as a "dangerous separatist".

During those drills, Beijing sent 62 military aircraft around Taiwan -- the highest single-day total this year -- as well as 27 naval vessels, according to Taipei's defense ministry.

On Friday, the ministry said it had detected 36 Chinese warplanes and six naval vessels operating around Taiwan during the 24-hour period leading up to 6:00 am (2200 GMT).

"35 of the aircraft crossed the median line of the Taiwan Strait," the ministry said in a statement, referring to a line bisecting the 180-kilometre (110-mile) waterway that separates Taiwan from China.

The ministry added that it had "monitored the situation and responded accordingly".

The latest incursion came after the Chinese coast guard seized a Taiwanese boat over suspected illegal fishing off the coast of China's Quanzhou and close to Taiwan's offshore Kinmen islands.

Taipei insisted that the boat was operating in a "traditional fishing ground" for both sides and demanded its immediate release.
