Russian and Chinese Aircraft Enter South Korean Air Defense Zone

South Korean fighter jets were scrambled after Russian and Chinese military aircraft entered the Korea Air Defense Identification Zone (KADIZ) during a joint aerial exercise earlier today.

Joint Military Maneuvers

The incident occurred in the morning over the East Sea and the South Sea. According to Seoul, the Russian and Chinese aircraft were participating in a joint bilateral aerial exercise.

Monitoring and Response

South Korea’s Joint Chiefs of Staff (JCS) reported that military aircraft repeatedly entered and exited the KADIZ. The South Korean military monitored the planes before they crossed the identification zone boundary. Seoul scrambled its own fighter jets in response, though the JCS confirmed that no sovereign airspace was violated.

Recurring Aerial Activity

Similar incidents involving Russian or Chinese military aircraft have been recorded at least once a year since 2019. The previous occurrence took place in December 2025, when nine aircraft entered the KADIZ.

Defining KADIZ

The KADIZ is not part of South Korea’s sovereign airspace but serves as a buffer zone for the early detection of foreign aircraft. While international practice suggests pilots should report flight plans in such zones, violation does not constitute an intrusion into national territory.

Divergent International Stances

Russia does not recognize the South Korean identification zone. China maintains that the zone is not territorial airspace and asserts that all nations should have the freedom of movement within the area.
