Chinese fighters flew close to Japanese patrol planes, Tokyo expresses concern

Japanese government expresses concern to China over dangerously close encounters between military aircraft, emphasizing need for prevention of recurrence.

Chinese fighter jets flew unusually close to Japanese military patrol planes over the weekend, Tokyo said, after two Chinese aircraft carriers were spotted operating simultaneously in the Pacific for the first time.

"We have expressed serious concern to the Chinese side and solemnly requested prevention of recurrence," Chief Cabinet Secretary Yoshimasa Hayashi said on Thursday, referring to the June 7-8 incidents in which Tokyo said Chinese jets flew as close as 45 metres (148 feet) to Japanese planes.

On Saturday, a Chinese J-15 jet from the aircraft carrier Shandong chased a Japanese P-3C patrol aircraft for about 40 minutes, according to Japan's Defence Ministry.

On Sunday, a J-15 chased a P-3C for 80 minutes, crossing in front of the Japanese aircraft at a distance of only 900 meters (2,950 feet), it said.

A spokesperson at the ministry's Joint Staff Office declined to disclose whether the same planes were involved in the incidents on both days.

The P-3C aircraft, belonging to Japan's Maritime Self-Defense Force based in the island of Okinawa, were conducting surveillance over international waters in the Pacific, according to the Ministry.

"Such abnormal approaches by Chinese military aircraft could potentially cause accidental collisions," the Ministry said in a statement on Wednesday, attaching close-up images of the J-15 jet it took on Sunday. There was no damage to the Japanese planes and crew, it added.
