U.S. ordered TSMC to halt shipments to China of chips used in AI applications, source says

The U.S. has reportedly ordered TSMC to halt shipments of advanced chips to Chinese customers that are often used in artificial intelligence applications.
The Department of Commerce sent a letter to TSMC imposing export restrictions on certain sophisticated chips, of 7 nanometer or more advanced designs, destined for China that power AI accelerator and graphics processing units (GPU), a source said.
It comes just weeks after TSMC notified the Commerce Department that one of its chips had been found in a Huawei AI processor, as Reuters reported last month.
