The US is investigating whether Huawei accessed advanced American chip technology via TSMC, despite a ban on such sales.

The U.S. is reportedly probing whether TSMC is making AI or smartphone chips with Huawei, currently barred from accessing chips made with U.S. technology.

Taiwanese chipmaker TSMC said on Friday that it was a law abiding company and committed to complying with laws and regulations, including export controls, following a media report the U.S. government was probing their dealings with China's Huawei.
