US may target Samsung, Hynix, TSMC operations in China

The U.S. Department of Commerce is considering revoking authorizations granted in recent years to global chipmakers Samsung, SK Hynix and TSMC, making it more difficult for them to receive U.S. goods and technology at their plants in China, according to people familiar with the matter.

The chances of the United States withdrawing the authorizations are unclear. But with such a move, it would be harder for foreign chipmakers to operate in China, where they produce semiconductors used in a wide range of industries.
