Warcraft from the Chinese Air Force flew over the Bashi Channel and the Miyako Strait on Friday in a west Pacific drill, an Air Force spokesman said Saturday.

The overflight involved "multiple types of warplanes," meeting the set target, spokesman Shen Jinke said while responding to media inquiries.

The routine high sea drill was an common practice among all countries close to sea, Shen said. "It accords with international law and practice, doesn't aim at any specific country, region or target, and is legitimate, reasonable and justified," he said.

Shen said the Chinese Air Force is a strategic military force and its strategic power should match with national interest.

The Air Force will continue to conduct regular high sea drills and further improve its capabilities in safeguarding national sovereignty, security and peaceful development, the spokesman said.
