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, effectively requiring them to halt shipments of equipment to wholly Chinese-owned factories producing advanced logic chips.

If effective, they could hobble China's chip manufacturing industry by forcing American and foreign companies that use US technology to cut off support for some of China's leading factories and chip designers.
