The U.S. Department of Commerce is investigating Taiwan Semiconductor Manufacturing Co. (TSMC) for allegedly aiding Huawei in developing smartphone and AI chip technologies. Reports suggest TSMC may have violated U.S. 5G export controls, which restrict Chinese companies from accessing American technology. Anonymous sources point to TSMC's involvement in manufacturing and designing chips for Huawei, despite TSMC's assertion of compliance with U.S. laws. This investigation highlights ongoing tensions between the U.S. and China in the tech sector, as Huawei continues to thrive amidst increased scrutiny and sanctions.
