The US has put dozens of Chinese entities on an export blacklist in the first big effort by the Trump administration to slow China’s ability to develop advanced artificial intelligence chips, hypersonic weapons and military-related technology.

The US Department of Commerce on Tuesday added more than 70 Chinese groups to the “entity list”, which requires any American company selling technology to them to have a licence. In most cases the licence request will be denied.

Among the listed groups are six Chinese subsidiaries of Inspur, a big cloud computing group that has worked with US chipmaker Intel, including one based in Taiwan. The Biden administration put Inspur on the entity list in 2023 but came under criticism for not adding its subsidiaries. Inspur did not immediately respond to a request for comment.
