Ten Chinese air force planes entered Taiwan's air defense zone on Wednesday, accompanying five Chinese warships engaged in "combat readiness" patrols, the island's defense ministry said. It was the second such incursion this week.
Taiwan, which China claims as its territory, has repeatedly complained of Chinese military activity near its borders, as Beijing tries to force the island to accept its sovereignty.
Taiwan's defense ministry said that starting at around 9 a.m. (0100 GMT), it detected a total of 25 Chinese aircraft out at sea, including J-10 and J-16 fighters, as well as H-6 bombers.
