The US and its allies have broadly blocked sales of the most advanced chips and manufacturing gear to China, including from three American firms — Applied Materials Inc, Lam Research Corp and KLA Corp. — as well as Dutch lithography system maker ASML Holding NV and Japanese toolmaker Tokyo Electron Ltd.
Key US lawmakers are pressing the Biden administration to block Huawei Technologies Co suppliers from buying American chipmaking gear, escalating efforts to prevent the sanctioned Chinese telecom giant from making progress on semiconductor manufacturing.
The top Republican and Democrat on the House China Select Committee outlined their concerns in a letter Wednesday to Commerce Secretary Gina Raimondo, whose agency oversees a pivotal trade restriction list as well as broader export controls on advanced chips and manufacturing tools. They pointed to Chinese companies Pengxinxu, SwaySure Technology, Qingdao Si’En and “potentially many others” as likely members of Huawei’s “clandestine network,” citing Bloomberg reporting.
