Biden to hit China with broader curbs on U.S. chip and tool exports

The Biden administration plans next month to broaden curbs on U.S shipments to China of semiconductors used for artificial intelligence and chipmaking
tools, several people familiar with the matter said.
The Commerce Department intends to publish new regulations based on restrictions communicated in letters earlier this year to three U.S. companies — KLA Corp, Lam Research Corp and Applied Materials Inc, the people said, speaking on the condition of anonymity. The plan for new rules has not been previously reported.
The letters, which the companies publicly acknowledged, forbade them from exporting chipmaking equipment to Chinese factories that produce advanced semiconductors with sub-14 nanometer processes unless the sellers obtain Commerce Department licenses.
The rules would also codify restrictions in Commerce Department letters sent to Nvidia Corp and Advanced Micro Devices last month instructing them to halt
shipments of several artificial intelligence computing chips to China unless they obtain licenses.
