On June 11, the Japanese Ministry of Defense speculated that Chinese jet fighters drew "unusually close" to its surveillance aircraft. Japan even protested to China as if the claims were true.

In response, the Chinese Ministry of National Defense published a video that shows how two Japanese surveillance aircraft intruded into the East China Sea Air Defense Identification Zone, and took actions endangering a Chinese surveillance plane. Finding itself in an untenable position, Japan demanded China delete the video.

This is not the first time that Japan has played the trick of a thief crying, "Stop thief". On May 24, the Japanese government claimed that Chinese military planes approached their surveillance aircraft, but it was soon revealed that Japanese military planes intruded into the airspace of the joint military exercises being conducted by China and Russia first. On June 14, Japan claimed that a Chinese frigate "could have" directed fire-control radar at the Japanese destroyer Sawagiri on May 29, but at the same time admitted there is "no conclusive evidence".
