On March 26, the U.S. Department of Commerce's Bureau of Industry and Security issued two directives on Tuesday local time, adding over 50 Chinese technology companies and institutions to the 'Entity List.' This measure is anticipated to come into force on March 28. One directive specifically targets 12 companies involved in the advancement of large AI models, servers, and the supercomputing industry in China, encompassing the Beijing Academy of Artificial Intelligence, Ningchang Information Industry, the server brand Suma under Sino-Kernel, and subsidiaries of Inspur Information located in mainland China, Hong Kong, and Taiwan. The second directive encompasses 42 Chinese companies, 19 Pakistani companies, and several companies from Iran, South Africa, and the United Arab Emirates. The U.S. Department of Commerce imposed sanctions on entities such as Saihao Instruments, Anhui Kehua Trade, and Chongqing Southwest Integrated Circuit Design Co., Ltd., citing "support for China's quantum technology development" as the rationale. Furthermore, the U.S. included dozens of Chinese companies on the Export Control List, justifying this action on the basis of "military involvement".
