WASHINGTON, Aug 29 (Reuters) - The U.S. will make it

more difficult for global chipmakers Samsung, SK

Hynix ( HXSCF ) and Intel ( INTC ) to produce chips in China

by revoking permission for the companies to receive American

semiconductor manufacturing equipment there, according to the

Federal Register.

The U.S. Commerce Department had granted the authorizations

for the companies to make chips in China as exceptions to

sweeping restrictions on the sale of semiconductor equipment to

China in 2022.

The companies will now need to obtain licenses to buy the

equipment in China.
