Still tension between China and Taiwan. "Since 5 a.m. today, local time, 37 Chinese military aircraft have entered Taiwan's airspace." The announcement was made in the early hours of dawn by the Taiwanese Ministry of Defense on Twitter.

This morning, 37 PLA aircraft, including J-11, J-16, H-6, YU-20 and AWACS, subsequently entered Taiwan's southwestern airspace. The Taiwanese Armed Forces are monitoring the situation closely and in response have sent CAP aircraft, military vessels and land-based missile systems."

The area crossed by Chinese aircraft, reports the Ministry of Taiwan, is part of the air defense zone of the island. China has regularly flown its air force over the skies near the island over the past three years, though not in Taiwan's territorial airspace.

China has recently begun to use drones in air raids around Taiwan: the first case dates back to April 28, when an unmanned TB-001 combat aircraft had operated an overflight around the island from the south-west side, passing around the southern, south-eastern and eastern part, before leaving the airspace north of Taiwan.

Also on the same day, Taiwan had identified a drone in the southern part of the island's Defense Area (Adiz). On May 12, however, among the thirteen Chinese military planes that had made a raid in the Adiz of Taiwan there was also a CH-4 reconnaissance and combat drone, which had operated a flight around much of the island, according to the findings of the Taipei Ministry of Defense.

On May 27, local authorities had announced that "a fleet of the People's Liberation Army composed of three ships, led by the aircraft carrier Shandong" had crossed "the Taiwan Strait around noon today west of the median line heading north. We are closely monitoring their movements and will respond accordingly."
