China supplies drone parts to Iran, Russia

Oil, drones, and sanctions are colliding in one story now. The immediate news is about oil — China on May 3 formally told domestic companies not to comply with U.S. sanctions on five refineries accused of buying Iranian crude. But the bigger picture is that this sits next to a second track: Chinese companies keep showing up in Iran’s and Russia’s drone supply chains. Put those together and the stakes get pretty obvious — more cash for Tehran, more components for unmanned weapons, and a much harder sanctions fight. (money.usnews.com) ### What happened this week? China’s commerce ministry issued an injunction under its blocking rules telling firms not to recognize or comply with U.S. sanctions on five Chinese refineries accused of purchasing Iranian oil. That is the sharpest public pushback yet against Washington’s latest “maximum pressure” squeeze on Tehran, because Beijing is no longer just objecting rhetorically — it is telling companies to ignore the penalties.

The five named by the U.S. are Shandong Shouguang Luqing Petrochemical, Shandong Shengxing Chemical, Hebei Xinhai Chemical Group, Shandong Jincheng Petrochemical Group, and Hengli Petrochemical’s Dalian refinery. Treasury said these “teapot” refiners have collectively bought and refined billions of dollars’ worth of Iranian oil, and its April 28 alert said they remain central to imports of Iranian crude through 2026.

Treasury says China currently buys around 90% of Iran’s total oil exports, with teapot refiners taking the majority. If Beijing shields those buyers, Tehran keeps a major revenue stream alive even while Washington tries to choke it off. That revenue does not map one-to-one into drones, obviously, but it helps keep the broader military and procurement system funded. (ofac.treasury.gov) ### Where do the drone parts come in? On the Iran side, U.S. sanctions in July 2025 and November 2025 targeted entities in China, Hong Kong, and elsewhere for procuring technology and equipment for Iran’s UAV and missile programs. Those actions matter because they are not speculative — they identify actual procurement networks moving components into Iranian weapons production. In plain English, Ch(ofac.treasury.gov)Washington traces how Iran gets hard-to-source parts. (state.gov) ### And what about Russia? Russia has the parallel version of the same problem. A March 24 investigation by Nordsint and The Insider said Chinese manufacturers were willing to sell critical drone components to Russian military-linked buyers despite China’s export controls, including fiber-optic equipment used in cable-guided FPV dron(state.gov)eeps leaking into Russia’s drone war machine. (nordsint.org) ### Is Europe reacting too? Yes — and that is a sign this is no longer just a U.S.-China sanctions spat. The EU’s 20th Russia sanctions package, adopted on April 23, added 117 listings and expanded anti-circumvention tools. Separate reporting around that package said Chinese and Hong Kong entities were again in the frame for supplying dual-use goods to Russia’s military-industrial base.

That gives sellers deniability and makes enforcement slow. It is like trying to stop a weapons program by policing a giant electronics market one invoice at a time. ### Bottom line? This week’s oil mo(fieldfisher.com) against enforcement in public. And when that happens alongside repeated Chinese links to Iranian and Russian drone procurement, the story stops looking like isolated violations and starts looking like a durable sanctions-resistant ecosystem.
