Biden to hit China with broader curbs on US chip and tool exports

The letters forbade them from exporting chipmaking equipment to Chinese factories that produce advanced semiconductors unless sellers obtain Commerce Department licenses.

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.
