11th China-Russia Joint Strategic Air Patrol: What Happened, How South Korea Responded, and the Evolution of a Bilateral Air Campaign Since 2019

What Happened During the 11th Patrol

The air forces of China and Russia dispatched a combined force that included:

• Russian aircraft: Tu-95MS strategic bombers, Su-30SM and Su-35S fighter jets
• Chinese aircraft: H-6K bombers, J-10C fighters, and a KJ-500A airborne early warning and control (AWACS) aircraft

According to China's Ministry of National Defense, the patrol was conducted under the annual cooperation plan between the two militaries and demonstrated "their resolve and capability to jointly safeguard regional stability" . Russia similarly stated that no foreign airspace was violated and that the mission, which originated over the Sea of Japan, proceeded as planned . The inclusion of fighter escorts and an AWACS platform marked the first time such assets participated in the patrol series, signaling a move toward more complex, multi-role operations beyond bomber-only missions .

How South Korea and Japan Responded

South Korea's Joint Chiefs of Staff said it detected the aircraft before they entered the KADIZ — which covers a large area over the East Sea (Sea of Japan) and South Sea — and deployed Air Force fighter jets to prepare for any contingency . The military confirmed the aircraft "entered and then left the Korea Air Defence Identification Zone without entering South Korean territorial airspace" . Japan's Defense Ministry also scrambled fighter jets, tracking four Chinese H-6 bombers and two Russian Tu-95 bombers, among other aircraft . No hostile engagement occurred, but the response was consistent with how both nations have handled all prior such patrols since 2019.

The Broader Context: An Annual Tradition Since 2019

The first joint strategic air patrol between the People's Liberation Army Air Force (PLAAF) and the Russian Aerospace Forces (VKS) took place on July 23, 2019, over the Sea of Japan and East China Sea. Russia described it as its first long-range collaborative air patrol with China in the Asia-Pacific region . That inaugural mission drew warning shots from South Korea and a strong objection from Japan, setting the tone for subsequent interactions .

Since then, the patrols have occurred at least once per year under an annual cooperation plan . The 10th patrol took place in December 2025 over the East China Sea and western Pacific, lasting eight hours . The 11th mission, in June 2026, was the first to include fighter escort and AWACS support, reflecting a steady escalation in scale and interoperability . A June 2026 U.S. Congressional Research Service report noted that Russia and China have conducted an increasing number of combined patrols and exercises in the Asia-Pacific since 2014 .

Nearly every patrol has triggered fighter jet scrambles by South Korea and Japan, and occasionally formal diplomatic protests, because aircraft routinely transit the KADIZ without prior notification . These patrols are widely interpreted as a signal of deepening Sino-Russian military cooperation aimed at counterbalancing the U.S.-Japan-South Korea alliance architecture in the Indo-Pacific .

What's New in 2026?

While the 10th patrol in December 2025 involved bombers and lasted eight hours, the 11th patrol stood out for two reasons:

1. Fighter and AWACS inclusion — Su-30SM, Su-35S, and J-10C fighters provided air cover, while a KJ-500A AWACS aircraft managed command and control, a first for the series .
2. Timing — The patrol occurred just days after Taiwan concluded five days of combat readiness drills, leading some analysts to interpret the flight as a calibrated message to Taipei and its allies .

Official statements from Beijing and Moscow described the flight as a regular exercise demonstrating shared resolve for regional stability. Independent sources, however, noted that the mission directly challenged the operational confidence of the U.S. and its Indo-Pacific allies .
