Japan’s Ministry of Defense protested a dangerous encounter on December 6, 2025, when Chinese Navy J-15 fighters from the carrier Liaoning illuminated Japanese Air Self-Defense Force F-15s with fire-control radar near Okinawa. The two incidents, occurring over international waters southeast of the island, represent an escalation in regional tensions. Japan characterized the radar lock-ons as hostile acts exceeding safe operational standards, while Beijing denied wrongdoing and accused Tokyo of harassment. The confrontation reflects mounting pressure in the region as Japan signals potential military support for Taiwan.
