China-Russia Joint Sea-2026 Naval Exercise Begins

China and Russia officially launched the “Joint Sea-2026” naval exercise on Monday, with a Russian task force arriving at the port of Qingdao in eastern China’s Shandong Province for the week-long drills in the Yellow Sea. The opening ceremony was held at a naval base of the People’s Liberation Army Navy (PLAN), with both sides committing core naval assets to the operation, according to TASS.

Forces and Scope

The Russian contingent, led by the Slava-class guided-missile cruiser Varyag — flagship of the Russian Pacific Fleet — includes the frigate Rezkiy, the Kilo-class submarine Ufa, and the rescue vessel Igor Belousov. China has deployed the Type 052D guided-missile destroyers Kaifeng and Anshan, the Type 054A frigate Wuhu, the supply ship Kekexilihu, the submarine rescue ship Yangchenghu, and one submarine. Both sides have also assigned shipborne helicopters and marine personnel, as reported by People’s Daily.

The exercise, themed “Joint Response to Maritime Security Threats,” will run from July 6 to July 13 and is structured in three phases: force assembly, port planning and coordination, and at-sea operations. During the at-sea phase, participating forces will conduct joint reconnaissance, air and missile defense, maritime strike operations, anti-submarine warfare training, and joint search-and-rescue missions, including simulated submarine crew rescue using deep-submergence vehicles.

Official Stance and Expert Analysis

Russian exercise director Rear Admiral Sergey Sinko stressed during the opening ceremony that the drills “are defensive in nature and are not directed against any third country,” according to TASS. China’s Ministry of National Defense described the exercise as “part of the annual cooperation plan between the two militaries” aimed at “jointly responding to security challenges and safeguarding regional peace and stability,” as reported by Xinhua.

Chinese military affairs expert Song Zhongping, interviewed by the Global Times, noted that both sides committed “core operational naval forces” to the exercise, underscoring “the scale of the operation and its elevated level of realism and combat-oriented training.” Song said the deployment of advanced frontline surface combatants — including China’s Type 052D destroyers and Russia’s cruiser Varyag — reflects a high level of participation. He further argued that the exercise serves “not only to safeguard peace and stability in the region, but also to uphold the post-World War II international order,” and is intended to “deter unilateral actions by certain countries” — language widely interpreted as a reference to US-led alliances in the Indo-Pacific.

Strategic Context

The Joint Sea series is an annual bilateral naval exercise that has been conducted since 2012, with the frequency and scale of drills expanding significantly since Russia’s full-scale invasion of Ukraine in 2022. According to the MERICS think tank, Russia and China have held over 90 joint military exercises since 2003. In August 2025, the two navies conducted Joint Sea-2025 off Vladivostok, followed by their fifth annual joint naval patrol in the Pacific. Just last month, in June 2026, China and Russia conducted their 11th joint strategic air patrol, demonstrating what the Global Times described as “systematic deployment and high combat readiness.”

Post-Exercise Patrol and Geopolitical Implications

Following the conclusion of Joint Sea-2026 on July 13, select forces from both sides will conduct a joint maritime patrol in relevant areas of the Pacific Ocean, according to the Chinese Ministry of National Defense. This extension of the operation into blue-water environments signals the growing operational reach and interoperability of the two navies.

The exercises come amid heightened geopolitical tensions between China, Russia, and Western-led alliance systems. The location in the Yellow Sea — a strategically sensitive waterway bordered by China, North and South Korea — is likely to draw close attention from the United States, Japan, and South Korea. While both Beijing and Moscow characterize the drills as routine and defensive, the deployment of frontline combatants and the planned Pacific patrol underscore the deepening military coordination between the two powers under their “comprehensive strategic partnership of coordination for a new era.”

What to Watch

Analysts will be watching for any official reactions from Washington, Tokyo, and Seoul in the coming days, as well as the specific routes of the post-exercise Pacific patrol. The scale of this year’s exercise relative to previous iterations and any live-fire components will also offer further insight into the evolving capabilities and ambitions of the China-Russia military partnership.
