Despite U.S. and European bans on exporting critical components for suicide attack drones to Iran and Russia, Chinese companies have continued to supply those parts openly.
On May 5, the Wall Street Journal reported that Chinese firms are ignoring U.S. export controls and shipping engines, semiconductors, optical fiber, gyroscopes and other components needed to produce attack drones to Russia and Iran on a large scale. These are dual-use items—usable in both civilian and military systems—and if they slip through sanctions, they can materially increase a country’s combat capabilities.
Chinese customs data indicate drone-related parts have been exported to Russia and Iran in volumes totaling hundreds of shipping containers. U.S. officials say that while companies once tried to evade Western sanctions by falsifying export declarations, many now appear to flout the restrictions without even attempting to conceal shipments.
The WSJ also found that some Chinese firms publicly offered to sell Iran the German-made Limbach L550 engine used in Iran’s principal loitering munition, the Shahed-136. That drone has become a core offensive weapon Russia has used extensively in the war in Ukraine.
Where Western-made parts once typically transited through China or Hong Kong before reaching Iran and Russia, sources say an increasing share of components are now manufactured directly inside China. Ukrainian forces who dismantled Russian drones have documented large numbers of Chinese-made parts.
Beijing says exports of dual-use goods are controlled under domestic law and international export norms. Western governments, however, contend China is effectively turning a blind eye. Because fully stemming the flow of drone components is proving difficult, U.S. policy has shifted toward cutting off financing—targeting buyers and shipping networks tied to Iranian oil sales with sanctions. The aim is to shrink Iran’s revenue base and, in turn, reduce funds available for drone development and production.
