Many Chinese air force fighters and transports came close to Taiwan after the island tested a series of new missiles.
The Chinese military (PLA) sent many Su-30, J-10 and Y-8 transports into the air defense identification area (ADIZ) southwest of Taiwan Island, the island's defense agency.
Taiwan's air defense forces sent fighters to intercept and force the Chinese aircraft to leave the island's ADIZ.
The Taiwan Defense Agency expressed "deep concern" about the PLA's military aircraft operations, accusing mainland China of "unilateral action" and "undermining peace and stability in the region".
The Chinese Ministry of Defense has not commented on this information yet.
Taiwanese media reported that PLA fighters approached the southwestern area of the island at least 24 times at an altitude of 1,500-9,000 m during 7h07-9h30 on 9/9, shortly after the island tested the missile series.
The missile test was organized by the Zhongshan Institute of Science and Technology.
Military experts believe that Taiwan can test surface-to-air missiles, long-range cruise missiles and long-range anti-ship cruise missiles.
Taiwanese media claimed that the PLA's aircraft sought to gather intelligence on the island's weapons tests.
China sees Taiwan as part of its territory and is willing to use force to unify if necessary.
The Chinese Air Force in June repeatedly dispatched fighters, bombers and jet transports close to Taiwan after the island tested a missile that was believed to be a model Thien Cung 3 with a range of 200 km.
