The U.S. Department of Commerce announced today, Friday, that it would add 42 Chinese companies to a government list for export monitoring due to their support for the Russian military and defense industrial base. The department added that the entities listed supplied U.S.-origin integrated circuits to Russian companies linked to the defense sector. It also mentioned that it would add seven other entities in total from Finland, Germany, India, Turkey, the UAE, and Britain. The Department of Commerce stated in a statement that the integrated circuits include electronics used by Russia for precision guidance systems in missiles and drones launched against civilian targets in Ukraine. Matthew Axelrod, Assistant Secretary for Export Enforcement, said in the statement, "The addition of these entities to the list today sends a clear message: If you supply the Russian defense sector with U.S.-origin technology, we will find out and take appropriate action." Companies are added to this list when Washington deems them a threat to national security or foreign policy. Suppliers are then required to obtain licenses that are generally difficult to acquire before shipping goods to the listed entities. The Chinese embassy in Washington has not yet responded to a request for comment.
