Shipping documents show how a Chinese state company kept supplying Russia's drone factories with the raw material used in its long-range attack drones, Politico reported. Chinese parts have been recovered from downed Russian drones before. These records are the first to show the raw material shipped straight to the factory—a sanctioned arm of Russia's nuclear giant Rosatom.

Russia's mass-produced attack drones run on parts sourced worldwide that keep slipping past Western export controls, and Ukrainian cities take the hits almost nightly. Kyiv has spent the war naming the foreign suppliers behind that hardware, one component at a time.

What the documents show

The papers trace 46 metric tons of carbon-fiber chemicals from Jilin Chemical Fiber Group to Alabuga-Volokno, a Rosatom subsidiary in Tatarstan. The exporter disguised the cargo under a customs code meant for civilian fibers like nylon, said weapons expert David Albright, who studies Russia's drone production. That precursor, polyacrylonitrile, is the raw ingredient for the light carbon fiber in Russia's Shahed-type attack drones.

Drones of that type killed at least 15 people at a shopping mall in central Ukraine in August. Albright estimated the load could yield enough for as many as 1,300 kamikaze drones. The Kyiv-based Ukrainian Security and Cooperation Center, a think tank close to Ukraine's government, gathered the documents and shared them with Western governments. The US House Select Committee on China judged them legitimate, and Ukraine confirmed their authenticity.

Why Beijing can't plead ignorance

Alabuga-Volokno has faced Western sanctions since 2023 from the US, UK, EU, Ukraine, and others. Jilin faces none. Albright said the documents would let the State Department sanction the Chinese supplier. Serhii Kuzan, who heads the Ukrainian center, called China arguably the main and only source of these composite materials.

Former US officials rejected any idea that Beijing was unaware.

"The idea that Chinese state-owned enterprises can hide things from the Chinese government just doesn't wash," said Dennis Wilder, a former CIA deputy assistant director for East Asia and the Pacific.

Denials and a summit

Rosatom claimed it works in full compliance with the law. China's embassy in Washington called the evidence an attempt to "smear and scapegoat China," saying Beijing has never supplied lethal weapons.

The disclosure lands as US President Donald Trump prepares to meet Xi Jinping in Washington this month. In late August, Xi told Vladimir Putin their ties were set to strengthen.
