The US on Tuesday added more than 50 Chinese entities to its export blacklist as it seeks to crack down on the nation’s artificial intelligence, quantum computing and military advancements. 

In total, the Department of Commerce’s Bureau of Industry and Security added 80 foreign entities to the list on the basis of national security concerns, including firms from China, the United Arab Emirates, South Africa and Iran. 

The U.S. on Tuesday added dozens of Chinese tech companies to its export blacklist in its first such effort under the Donald Trump administration, as it doubles down on curtailing Beijing’s artificial intelligence and advanced computing capabilities.

The U.S. Department of Commerce’s Bureau of Industry and Security added 80 organizations to an “entity list,” with more than 50 from China, barring American companies from supplying to those on the list without government permits.

China protested Wednesday after the U.S. added dozens of companies to its export control list, including more than 50 based in China that it says sought advanced knowhow in supercomputing, artificial intelligence and quantum technology for military purposes.

Companies from Taiwan, Iran, Pakistan, South Africa and United Arab Emirates also were included in the roughly 80 companies added to the “entity list” of the Commerce Department’s Bureau of Industry and Security.
