A Chinese state-owned company shipped tens of tons of a critical aerospace material to a sanctioned Russian defense facility, providing the raw ingredients for what could be hundreds of kamikaze drones used against Ukrainian civilians and infrastructure. The findings, published by Politico in September 2026, represent some of the most direct evidence yet of Chinese state enterprise involvement in Russia’s drone production pipeline.
The company at the center of the investigation is Jilin Chemical Fiber Group, a state-owned manufacturer based in China’s northeastern Jilin province. According to the investigation, Jilin shipped approximately 46 metric tons of polyacrylonitrile, known in the industry as PAN-precursor, to a Russian facility earlier in 2026. The shipments were routed under civilian customs codes, obscuring their actual destination and purpose.
What PAN-precursor actually does
PAN-precursor is a polymer material that, once processed at high temperatures, becomes the lightweight, high-strength carbon fiber used in aerospace and military applications. Carbon fiber is a core structural component in the Geran drone, Russia’s domestic version of Iran’s Shahed kamikaze drone.
The 46 tons Jilin supplied could produce enough carbon fiber for up to 1,300 Geran-type drones, according to the investigation’s estimates. The destination for Jilin’s shipment was Alabuga-Volokno, a subsidiary of Rosatom, Russia’s state nuclear and advanced materials conglomerate. Alabuga-Volokno operates inside the Alabuga Special Economic Zone in Tatarstan, a facility that Western governments sanctioned in 2023 specifically because of its role in military production. Jilin Chemical Fiber Group is not currently sanctioned by any Western authority.
