Japan said on Sunday that Chinese fighter jets had aimed their radar at Japanese military aircraft in two “dangerous” incidents near Japan’s Okinawa islands, an account Beijing disputed.

Japan has protested to China after a Chinese military jet locked its radar on Japanese fighter jets near Okinawa

Japan's Defense Ministry says the Maritime Self-Defense Force has been monitoring the movements of the Chinese aircraft carrier Liaoning and accompanying vessels near Okinawa since Friday.

Koizumi reported that two of the Liaoning's J-15 fighter jets locked their radars on two Japanese F-15 fighter jets from approximately 4:32 p.m. to 4:35 p.m. and 6:37 p.m. to 7:08 p.m. on Saturday local time over international waters southeast of Japan's Okinawa Island.

The United States has for the first time criticised China for aiming radars at Japanese military aircraft during a training exercise last week, incidents that the Asian neighbours have given differing accounts of amid escalating tensions.
