Event Summary

Japan rejected China's claim that Japanese Self-Defense Forces fighter jets interfered with Chinese naval training, which China cited as the reason for locking radar on the Japanese planes. Japan's Chief Cabinet Secretary Minoru Kihara stated that the Air Self-Defense Force jets maintained a 'safe distance' from Chinese military aircraft off Japan — Okinawa Island and condemned the radar locks as 'dangerous acts'. The incident occurred on December 6, when Chinese J-15 aircraft from the carrier Liaoning locked radar on two ASDF F-15 jets over international waters. This event further escalated tensions between Japan and China, which were already high due to Japanese Prime Minister Sanae Takaichi's earlier remarks regarding a potential Chinese attack on Taiwan. China had previously criticized these comments, urged tourists not to visit Japan, suspended seafood imports, and postponed a trilateral culture ministers' meeting. Both nations have lodged protests, with China defending its actions as normal operations and accusing Japan of 'irresponsible hype'.
