Documents reviewed by Reuters indicate that senior Russian and Chinese officers oversaw covert training for Russian personnel in China, moving European concern beyond dual-use trade towards direct military learning linked to the war in Ukraine.

New documentary detail about covert Chinese training for Russian forces has pushed Europe’s debate over Beijing’s support for Moscow into more explicitly military territory.

Documents and European official assessments reviewed by Reuters indicate that Russian Defence Minister Andrei Belousov authorised personnel to attend courses at People’s Liberation Army facilities in 2025, with at least four Russian and Chinese generals directly involved. The reported programme included drones, electronic warfare, explosives and mines, as well as radiological, chemical and biological protection.

Reuters first reported in May that about 200 Russian personnel had trained in China and that some later returned to the war in Ukraine. The new material matters because it points to high-level approval and a structured programme, rather than informal contact or isolated technical exchange.

China has denied the account and continues to present itself as neutral. The evidence described in the reporting has not been independently published in full, so conclusions must remain tied to what the documents and officials are said to show. Even with that caveat, the implications for European security policy are substantial.

Beyond dual-use exports

European criticism of China has largely focused on machine tools, microelectronics, optical fibre and other goods reaching Russia through commercial supply chains. Defence Matters has examined claims that Chinese equipment and chips support Russian missile production.

Training is different. A component can have civilian and military uses, allowing Beijing to argue that normal commerce is being mischaracterised. Instruction delivered by the PLA to Russian military personnel is harder to separate from defence cooperation, particularly when the subjects have direct battlefield application.

Drone operations and electronic warfare are among the most rapidly evolving areas of the Ukraine war. Russian units have accumulated combat experience, while Chinese forces possess extensive industrial and technical resources but comparatively little recent battlefield experience. That creates the possibility of two-way learning: Russia gains access to Chinese systems and training infrastructure; China gains insight into how equipment and doctrine perform under sustained combat pressure.

Interoperability without an alliance treaty

China and Russia do not need a NATO-style mutual-defence commitment to generate military effects together. Repeated exercises, common procedures, officer exchanges and technical training can gradually improve interoperability without creating a formal alliance.

The reported involvement of senior generals suggests institutional ownership. It also makes the programme more relevant to NATO planners. Training involving chemical protection, drones and electronic warfare can improve Russia’s ability to sustain operations, protect forces and adapt tactics in Ukraine. Lessons may subsequently inform Chinese planning in the Indo-Pacific.

The relationship resembles other partnerships Moscow has developed under sanctions, though each has distinct limits. Defence Matters has reported how Russia-Iran military cooperation has moved into intelligence, drones and operational learning. The China relationship is economically larger and strategically more consequential.

A harder basis for European pressure

The EU has sanctioned Chinese companies accused of supporting Russia’s military-industrial base, but member states remain divided over how far to confront Beijing. Trade exposure, manufacturing dependence and concern about retaliation encourage caution.

Evidence of state-directed military training changes the argument. It allows European governments to say the issue is not simply weak export control or private companies exploiting loopholes. It is potential military assistance delivered through official institutions.

That could strengthen the case for listing additional entities, tightening controls on training-related technology and coordinating more closely with Asian partners. It may also affect the tone of EU-China diplomacy, where Beijing’s claim to be a peace mediator already sits uneasily with its economic support for Russia.

Sanctions alone cannot address military learning. European intelligence services will need to track personnel exchanges, training locations, doctrine and the movement of specialist equipment. NATO will also need to consider how China might absorb Russian lessons on air defence, drone saturation, electronic warfare and industrial mobilisation.

What Europe should not assume

The report does not prove that China directs Russian operations in Ukraine or that every trained individual was deployed there. Nor does it establish a fully integrated command relationship. Exaggerating the evidence would make it easier for Beijing to dismiss legitimate concerns.

The stronger conclusion is narrower: Russian and Chinese defence institutions appear willing to share training relevant to an ongoing European war, and the reported programme received approval at a senior level.

For NATO, that erodes the distinction between the European and Indo-Pacific security theatres. Russian combat experience can improve Chinese military preparation, while Chinese technology and training can help Russia sustain pressure on Ukraine.

European policy has often treated China as an economic challenge and Russia as a military one. The reported training shows why that separation is becoming harder to maintain.
