WASHINGTON, March 29 (Reuters) - The Biden

administration on Friday revised five-month-old rules aimed at

making it harder for China to access U.S. artificial

intelligence chips.

Those rules, released last October, seek to halt shipments

to China of more advanced artificial intelligence chips designed

by Nvidia ( NVDA ) and others, part of a raft of measures aimed

at stopping Beijing from receiving cutting-edge U.S.

technologies to strengthen its military.

The Commerce Department said on Friday it was making

clarifications and corrections effective April 4.
