China, Russia Conduct Joint Bomber Patrol in Northeast Asia

In a striking display of growing Sino-Russian military coordination, long-range bombers from China and Russia carried out a joint patrol through one of Japan’s most sensitive air corridors, triggering a swift response from the Japan Air Self-Defense Force (JASDF).

The latest manoeuvre highlights the increasing complexity of East Asia’s security environment at a time of heightened strategic rivalry in the region.

Joint Bomber Mission Over Strategic Waterway

On 9 December, China and Russia executed a coordinated bomber sortie through the Miyako Strait, a crucial international air passage located between Okinawa and Miyako Island. According to Japan’s Ministry of Defence, the operation involved a pair of Russian Tupolev Tu-95 “Bear” strategic bombers linking up with two Chinese Xian H-6 bombers over the East China Sea before proceeding toward the Pacific.

The Miyako Strait is one of China’s few access routes for its air and naval forces to enter the open Pacific, making it a frequent hotspot for military activity and surveillance flights.

Intrusion Into Korea ADIZ – No Airspace Violation

Around 10:00 a.m. local time, the situation escalated further when seven Russian aircraft and two Chinese aircraft entered the Korean Air Defense Identification Zone (KADIZ) over the Sea of Japan, South Korea’s Joint Chiefs of Staff reported.

Although no violation of sovereign airspace occurred, South Korea—like Japan—monitors its ADIZ to track unidentified or approaching aircraft. ADIZs extend well beyond a country’s territorial airspace and are not recognized under international law, but they remain standard practice for early identification.

Detailed Flight Path and Joint Operations

Japan’s Joint Staff Office released an overview of the coordinated mission:

• The two Russian Tu-95 bombers flew from the Sea of Japan, heading south into the East China Sea.
• There, they rendezvoused with the two Chinese H-6 bombers.
• The combined formation then carried out a long-distance patrol from the East China Sea into the Pacific Ocean off the coast of Shikoku.

Adding to the complexity, a group of Chinese J-16 fighter jets joined the bomber formation as it transited between Okinawa and Miyako Island into the Philippine Sea. On the return leg, four additional J-16s escorted the bombers back through the same air corridor into the East China Sea.

Japan also confirmed the presence of:

• One Russian A-50 Airborne Early Warning and Control (AEW&C) aircraft
• Two Russian Su-30 fighters
  operating in the Sea of Japan during the coordinated activity.

JASDF Scramble and Response

In response to the joint patrol, Japan promptly deployed fighter aircraft from the Japan Air Self-Defense Force’s Southwestern Air Defense Command. The scrambled Japanese fighters conducted interception and visual identification as the Sino-Russian aircraft transited through the ADIZ.

Japan’s Joint Staff Office also released photographs and a flight map documenting the movements of the Chinese and Russian aircraft, a standard measure used for transparency and strategic signalling.

Rising Strategic Coordination in the Region

This latest patrol marks another instance of deepening military cooperation between Beijing and Moscow. Joint flights through the Miyako Strait and the Sea of Japan have become more frequent in recent years, underscoring the two nations’ intent to challenge the regional surveillance networks of Japan, South Korea, and the United States.

For Japan, such missions reinforce the need for continuous vigilance, rapid response capability, and enhanced defence coordination with regional partners.
