U.S. Officials: China's SMIC Has Supplied Chipmaking Technology to Iran's Military

Two senior Trump administration officials revealed that SMIC, China's largest chipmaker, has been sending chipmaking tools to Iran's military industrial complex for approximately one year. The collaboration "almost certainly included technical training on SMIC's semiconductor technology." The disclosure threatens to escalate U.S.-China tensions as Washington wages war against Tehran while simultaneously seeking to constrain China's advanced chip industry. SMIC, already on a U.S. trade blacklist since 2020, denies military ties. The House Foreign Affairs Committee advanced the Chip Security Act in response.

Analysis
The SMIC-Iran channel represents a direct nexus between two U.S. adversary IC targets: Chinese technology transfer enabling Iranian military capability during active hostilities. SMIC was already under U.S. export controls; this disclosure suggests those controls failed to prevent the transfer. The Chip Security Act response from HFAC signals bipartisan appetite for tightening semiconductor export enforcement, but any new restrictions must avoid disrupting the broader chip supply chain during wartime.
