apan and South Korea scrambled fighter jets on Tuesday after Russian and Chinese military aircraft conducted a joint patrol near their airspace, the latest show of force amid rising tensions in the region.
The Patrol
Seven Russian and two Chinese aircraft entered South Korea’s Air Defense Identification Zone at approximately 10am local time on December 9, 2025. South Korea sent up fighter jets to “take tactical measures in preparation for any emergencies.”
Japan also scrambled jets to monitor the Russian and Chinese air forces conducting joint patrols around the country. The exercise lasted approximately 8 hours according to Russian state media.
The Russian aircraft entered near Ulleung Island and Dokdo, while Chinese aircraft entered near Ieodo. South Korea lodged a complaint with Chinese and Russian defense attaches based in the country.
Context
The joint patrol comes amid rising tensions between Tokyo and Beijing following Japanese Prime Minister Sanae Takaichi’s November remarks that Japan could be drawn into a Taiwan conflict.
Earlier in December, Chinese J-15 fighters locked fire-control radar on Japanese F-15 jets near Okinawa, an extremely hostile action that marks a significant escalation in regional military brinkmanship.
In December 2025, China deployed over 100 naval and coast guard vessels across East Asian waters, the largest maritime show of force in the region’s history. Japanese Defense Minister Shinjiro Koizumi said Japan was watching Chinese military movements “with great attention.”
Overview
The joint Russian-Chinese bomber patrol demonstrates deepening military coordination between Moscow and Beijing at a time of heightened tensions with Japan over Taiwan. Both South Korea and Japan’s decision to scramble fighters reflects concern over the growing frequency and scope of these joint operations near their airspace.
