The U.S. Department of Commerce strengthens export controls to restrict the flow of high-end chips to China

As Biden is about to leave office, the U.S. Department of Commerce has continuously issued new export control regulations. On January 15, its subordinate Bureau of Industry and Security (BIS) issued two new regulations. First, the export control of advanced computing power was updated, and the specification upper limit of the tape-out chip was expanded from the original 7 nanometers to 16 or 14 nanometers. Secondly, 27 AI companies and computing power companies in China and Singapore were included in the "Entity List" for strict control. These companies include China's Chuliang Electronics, intelligent computing chip company Suanneng Technology and its 13 subsidiaries, large model company Zhipu and its 10 subsidiaries, and 1 entity Keyi Hongyuan.
