TSMC has denied allegations that it is being investigated by the U.S. government for its business dealings with Huawei.

Reports had suggested that TSMC's chips were found in Huawei products, potentially violating U.S. export controls. However, TSMC has stated that it has not supplied any chips to Huawei since September 2020 and is committed to adhering to all applicable laws and regulations.

A TSMC chip was recently discovered in a Huawei product, raising concerns about possible export violations. TSMC has notified the U.S. Commerce Department about this discovery.

The situation highlights the ongoing tensions between the U.S. and China in the technology and trade sectors.

TSMC's shares have declined as investors worry about the potential consequences of these allegations. The semiconductor industry is closely monitoring the situation due to its potential impact on the market and stakeholders.
