China Covertly Trained Russian Troops Now Fighting in Ukraine
Beijing's secret military training program for 200 Russian personnel marks first confirmed direct operational involvement in the war, fundamentally reshaping Western deterrence calculations.
China’s armed forces secretly trained approximately 200 Russian military personnel in late 2025, with some now deployed in active combat in Ukraine—the first confirmed instance of direct Chinese personnel training beyond equipment sharing, according to an exclusive Reuters investigation.
The revelation, based on leaked Russian military documents and intelligence assessments from three European agencies, establishes that Beijing has crossed from passive sanctions evasion into direct operational involvement in Europe’s largest land war since 1945. Russian personnel trained at Chinese military academies in drone warfare, electronic warfare, and combined arms operations have been confirmed fighting in Crimea and Zaporizhzhia regions, with ranks ranging from junior sergeant to lieutenant colonel.
The Secret Agreement
Senior Russian and Chinese officers signed the training framework in Beijing on July 2, 2025, according to Reuters. The classified document mandated dual-language covert training sessions focused predominantly on drones and explicitly prohibited media coverage or disclosure to third parties. The agreement specified hundreds of Chinese troops would undergo reciprocal training at Russian military facilities.
Four separate training courses documented between November and December 2025 paint a detailed picture of operational integration. At the PLA Ground Forces Army Infantry Academy in Shijiazhuang, 50 Russian personnel trained on combined arms warfare, including firing 82mm mortars while using UAVs to identify targets. A November course at Nanjing University of Military Engineering covered explosives technology, mine construction, demining, and IED removal. Photographs obtained by intelligence services show Russian soldiers in uniform being instructed by Chinese military personnel. Air defence training at a Zhengzhou facility included electronic warfare rifles, net-throwing devices, and counter-drone systems.
“By training Russian military personnel at an operational and tactical level who then participate in Ukraine, China is far more directly involved in the war on the European continent than previously known.”

Operational Integration
European intelligence agencies confirmed that a significant number of the trained personnel were ranking military instructors, positioning them to cascade knowledge through Russia’s command structure. This multiplier effect amplifies the program’s tactical impact far beyond the 200 direct participants. The training focused heavily on drone operations and counter-drone systems—critical capabilities where Russian forces have struggled against Ukrainian innovation throughout the war.
The reciprocal arrangement reveals Beijing’s strategic calculus. Russia is training approximately 600 Chinese military personnel in 2025 at Russian bases, focusing on countering Western weapons using combat experience from Ukraine, per Kyiv Post reporting citing Ukrainian Defense Intelligence Directorate sources. This two-way exchange transforms China-Russia military cooperation from symbolic joint exercises into practical operational co-development.
Strategic Implications
The program undercuts Beijing’s stated neutrality on Ukraine. China’s Foreign Ministry maintains “an objective and impartial stance” and works to “promote peace talks,” but the documented training of combatants contradicts this positioning. The revelation arrives as MERICS documents that China and Russia conducted 11 joint military exercises in 2024—more than any previous year—with nearly one-third of over 90 total exercises since 2003 occurring after February 2022.
For Western policymakers, the training program forces recalibration of intervention red lines. If China provides operational-level military expertise rather than just equipment, NATO’s deterrence posture must account for a Sino-Russian integrated threat beyond the European theatre. Ukrainian intelligence has characterized Russia’s decision as illustrating “the Russian regime’s intention to align with China in a course of global confrontation with the West,” according to the Kyiv Post.
- China trained 200 Russian personnel at four PLA facilities between July and December 2025, with confirmed combat deployment in Ukraine
- Training covered drones, electronic warfare, combined arms, and counter-drone systems—critical capability gaps for Russian forces
- Secret July 2025 agreement mandated media blackout and prohibited disclosure to third parties
- Russia reciprocally training 600 Chinese personnel in Ukraine-derived combat tactics
- Program represents qualitative escalation from equipment/intelligence sharing to operational-level integration
Taiwan Contingency Calculus
The reciprocal nature of the training program carries implications for Taiwan. Chinese personnel learning from Russian combat experience—particularly urban warfare, drone operations, and countering Western weapons systems—directly enhances PLA capabilities relevant to a Taiwan contingency. Earlier reporting by CNN on leaked military contracts showed Russia training a Chinese airborne battalion, a unit type critical for amphibious operations.
The program also reveals the extent of Russia’s degraded military capacity. Moscow’s need for Chinese training infrastructure—rather than simply conducting joint exercises on Russian soil—signals institutional knowledge gaps three years into the Ukraine war. Trade between Russia and China reached $220 billion in 2025, but the military training exchange suggests a dependence that transcends commercial ties.
Detection and Intelligence Gaps
The revelation raises questions about Western intelligence capabilities. The training program operated for at least six months before detection, involving hundreds of personnel at multiple Chinese military installations. The leaked Russian military documents and photographic evidence suggest internal Russian security failures rather than sophisticated Western penetration. If similar programs exist without documentary leaks, detection timelines could extend far longer.
Analysis by the Center for Strategic and International Studies documents steady expansion in China-Russia military interoperability through March 2026, but the covert training program represents a dimension not captured in publicly observable exercises. The classification level and compartmentalization—requiring senior officer signatures and prohibiting third-party disclosure—indicates sophisticated operational security that Western intelligence struggled to penetrate in real time.
What to Watch
Monitor whether Beijing expands the program beyond the initial 200-personnel cohort or extends training to additional Russian military branches. The European intelligence assessment suggests this represents an inaugural program rather than a one-time event. Watch for Western diplomatic responses—particularly whether the EU or NATO formally designate China as a co-belligerent or impose targeted sanctions on PLA training facilities involved in the program. The scope of reciprocal Chinese training in Russia will indicate whether Beijing views Ukraine as a laboratory for Taiwan contingency preparation. Finally, track whether similar training programs emerge between Russia and other Chinese security partners, particularly in Central Asia, as a model for operational integration without formal alliance structures.
