On December 9, Seoul shot down seven Russian and two Chinese aircraft that entered its Air Defense Identification Zone, without breaching the country’s territorial airspace.
South Korean Fighters in the Skies
At about 10:00 local time on 9 Dec., Seoul reported firing down seven Russian and two Chinese planes that had entered the Air Defense Identification Zone (KADIZ). The aircraft stayed in the zone for roughly an hour along the eastern and southern coasts before leaving without violating the country’s territorial airspace, as confirmed by the Joint Chiefs of Staff.
Russia and China Maneuvers
Russian and Chinese military aircraft often conduct joint exercises around the Korean Peninsula, typically twice a year. An earlier incursion occurred on 29 Nov 2023, and in March, only Russian planes repeatedly breached the zone. The KADIZ is an arbitrarily drawn boundary intended for early detection and response to approaching military aircraft; crossing it is not a violation of airspace. Russia does not recognise the South Korean identification zone.
Tension Between China and Japan
During the weekend, Chinese fighters posed a threat near Okinawa, a major U.S. naval base, firing a fire‑control radar signal toward Japanese aircraft—an act deemed beyond what is necessary for flight safety. Japanese Defense Minister Shinjiro Koizumi said Japan would take decisive but calm actions, while China alleged Japanese fighters were dangerously close. Incidents near the Diaoyu/Senkaku islands have amplified a diplomatic spat triggered by remarks from Japanese Prime Minister Sanae Takaichi.
