PALO ALTO, U.S./NEW YORK -- U.S. President Joe Biden signed an executive order Wednesday that restricts certain American investments in mainland China, Hong Kong and Macao in high-tech sectors such as artificial intelligence, semiconductors and quantum technology.
The move -- criticized by China -- prohibits U.S. persons from making "certain transactions" in semiconductors and microelectronics, quantum information technologies and AI sectors and requires them to notify the Treasury Department when making such transactions.
