China and Russia will hold joint naval and air exercises in the Yellow Sea near Qingdao this month, followed by a combined maritime patrol in the Pacific, the Chinese Ministry of National Defence confirmed on Sunday. The drills, named “Maritime Interaction–2026,” are scheduled from 6 to 13 July and involve surface combatants, submarines, and support vessels from both fleets, including the Russian Pacific Fleet’s cruiser Varyag and destroyers from China’s North Sea Fleet. According to the Chinese defence ministry, the recurring exercise aims to “jointly counter security challenges and maintain regional peace and stability,” and is part of an annual collaboration framework that officials in Moscow describe as a “traditional” partnership independent of the broader political situation.

Taipei has responded by reinforcing military education and issuing diplomatic protests. Taiwan’s Ministry of National Defence announced the restoration of formal “anti-communist” classes for military academy graduates, citing a heightened threat of “military and infiltration danger” from the mainland. In parallel, the Mainland Affairs Council (MAC) condemned recent Chinese coastguard patrols east of Taiwan as an “unlawful expansion of authority” that flouts international law and undermines regional stability, reiterating that Beijing has “absolutely no sovereign rights” over the island’s exclusive economic zone. The council said it would take all necessary measures to protect sovereignty, while the Coast Guard Administration confirmed it was shadowing two Chinese vessels off Hualien county.

Viewed from Beijing, the drills and patrols are routine acts of sovereignty enforcement. A Chinese coastguard statement described the east-Taiwan operation as “law enforcement patrols” to “firmly safeguard China’s territorial sovereignty and maritime rights.” Chinese officials have repeatedly urged Washington to exercise “maximum caution” over Taiwan, and state media frame the exercises with Russia as a contribution to regional order. The Russian defence ministry has disclosed few operational details but stressed that the joint naval work, including anti-submarine and air-defence drills, serves to improve interoperability. The two militaries conducted their eleventh strategic air patrol over the Sea of Japan and East China Sea in June, underscoring a pattern of deepening military coordination.

The confluence of large-scale exercises, persistent maritime patrols, and Taiwan’s defensive posturing amplifies frictions across the first island chain. Taiwanese authorities reported tracking over 110 Chinese military and coastguard ships in the chain’s arc earlier this month, which National Security Council Secretary-General Joseph Wu labelled a “clear sign of expansionism.” Although Beijing casts its activities as peacetime safeguards, long-stalled military-to-military communication channels between the US Pacific Command and China’s Eastern Theatre Command, noted during a security forum in Beijing, leave few off-ramps for incident management in the Taiwan Strait. Upon conclusion of the drills around Qingdao, the joint Russian-Chinese flotilla is to sortie into the western Pacific for extended patrols, a move likely to be monitored closely by allied navies in the region.
