The additions included companies that are customers of Intel and Nvidia, and one firm that was the focus of a New York Times investigation last year.
The Trump administration on Tuesday added 80 companies and organizations to a list of companies that are barred from buying American technology and other exports because of national security concerns.
The move, which targeted primarily Chinese firms, cracks down on companies that have been big buyers of American chips from Nvidia, Intel and AMD. It also closed loopholes that Trump administration officials have long criticized as allowing Chinese firms to continue to advance technologically despite U.S. restrictions.
One company added to the list, Nettrix Information Industry, was the focus of a 2024 investigation by The New York Times that showed how some Chinese executives had bypassed U.S. restrictions aimed at cutting China off from advanced chips to make artificial intelligence.
Nettrix, one of China’s largest makers of computer servers that are used to produce artificial intelligence, was started by a group of former executives from Sugon, a firm that provided advanced computing to the Chinese military and built a system the government used to surveil persecuted minorities in the western Xinjiang region.
In 2019, the United States added Sugon to its “entity list,” restricting exports over national security concerns. The Times investigation found that, six months later, the executives formed Nettrix, using Sugon’s technology and inheriting some of its customers. Times reporters also found that Nettrix’s owners shared a complex in eastern China with Sugon and other related companies.
After Sugon was singled out and restricted by the United States, its longtime partners — Nvidia, Intel and Microsoft — quickly formed ties with Nettrix, the investigation found.
