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

The report from The Information regarded that TSMC possibly helped Huawei in manufacturing their much-needed smartphone chipsets, with the Taiwanese company best known for their partnerships with the likes of Apple. Additionally, sources claimed that TSMC also allegedly helped Huawei in designing its self-made AI chips.

An unconfirmed report says that the US Department of Commerce is making a probe into TSMC whether it's breaking America's sanction on Huawei.

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.
