突发！美国对华制裁升级，封杀中企子公司

Core Viewpoint - The recent export control regulations by the U.S. Department of Commerce are seen as an extension of the U.S. government's efforts to restrict Chinese companies, particularly in the semiconductor and AI sectors, by imposing similar restrictions on subsidiaries owned more than 50% by sanctioned entities [2][3][4]. Group 1 - The U.S. Department of Commerce has introduced rules to prevent sanctioned companies from using subsidiaries to circumvent export controls, specifically targeting Chinese AI chip giants [3][4]. - Companies with at least 50% ownership by entities on the U.S. Entity List will now face the same export restrictions as their parent companies, increasing scrutiny on shipments to these subsidiaries [3][4]. - The new regulations align the Department of Commerce's approach with the Treasury Department's sanctions enforcement, standardizing the treatment of entities on the Entity List and Military End User List [3][4]. Group 2 - U.S. officials believe that the new regulations will not significantly impact trade flows, as they are designed to prevent sanctioned companies from exploiting subsidiaries as loopholes [4]. - Industry officials express concerns that the changes may complicate the process for companies trying to determine if potential customers are subject to additional restrictions [5].
