The Biden administration is considering blacklisting a number of Chinese semiconductor firms linked to Huawei Technologies after the telecommunication equipment giant notched a significant technological breakthrough last year, people familiar with the matter said.
The companies that could be blacklisted include chip makers Qingdao Si’En, SwaySure, and Shenzhen Pensun Technology, the people said, asking not to be named because they were not authorised to discuss non-public information. Biden officials are also weighing sanctions on China’s leading memory chip maker ChangXin Memory Technologies (CXMT).
Most of the Chinese entities that could be affected were previously identified as chip-making facilities acquired or being built by Huawei in a presentation by the Washington-based trade group Semiconductor Industry Association (SIA), according to people familiar with the matter.
No final decisions have been made, the people said. Bloomberg News first reported about SIA’s presentation in 2023.
