The Chinese military has revealed a bomber squadron with the East China Sea Fleet have recently conducted a long-range combat drill in the Sea of Japan.

The bombers traveled thousands of kilometers and conducted saturation attacks on vessels of a simulated enemy to improve their capability of continuous strikes at maximum range.

Navy officials say the drill was routine and in accordance with international law, and not aimed at any specific country, region or target.

Last week, Chinese naval warships also held a confrontation drill in the same waters.
