U.S. Orders TSMC to Halt Advanced AI Chip Exports to China

The decision follows the discovery of TSMC chips in Huawei products, prompting concerns over export control compliance.

The U.S. Department of Commerce has directed TSMC to stop exporting AI chips made with 7-nanometer technology or smaller to Chinese companies.
This move is part of broader U.S. efforts to restrict China's access to advanced semiconductor technology amid ongoing trade tensions.
The halt in shipments was prompted by the discovery of a TSMC chip in a Huawei AI processor, raising concerns about export regulation breaches.
China's semiconductor index surged as investors bet on increased self-reliance in response to the export restrictions.
Taiwan's regulations also prevent TSMC from producing its most advanced 2-nanometer chips overseas, keeping core technology within the country.
