Last month, the U.S. Commerce Department’s Bureau of Industry and Security (BIS) added eight technology entities based in China to its trade blacklist for engaging in activities contrary to national security. The move was enacted to prevent the diversion of U.S. technologies to China’s military advancement, Secretary of Commerce Gina M. Raimondo said in a statement.

The Department of Commerce said the sanctions are part of its “efforts to prevent U.S. emerging technologies from being used for China’s quantum computing efforts that support military applications, such as counter-stealth and counter-submarine applications, and the ability to break encryption or develop unbreakable encryption.” The sanctioned China-based technology entities “support the military modernization of the People’s Liberation Army and/or acquire and attempt to acquire U.S. origin-items in support of military applications,” according to the department.
