Biden administration imposes sweeping tech restrictions on China

New rules include measure to exclude China from using semiconductor chips made anywhere in world with US tools

The Biden administration on Friday published a sweeping set of export controls, including a measure to cut China off from certain semiconductor chips made anywhere in the world with US tools, vastly expanding its reach in its attempt to slow Beijing's technological and military advances.

The rules, some of which go into effect immediately, build on restrictions sent in letters earlier this year to top toolmakers KLA Corp, Lam Research Corp and Applied Materials Inc, in effect requiring them to halt shipments of equipment to wholly Chinese-owned factories producing advanced logic chips.
