An investigation has revealed that advanced semiconductor technology from Taiwan Semiconductor Manufacturing Company (TSMC) has been found in AI chips produced by Huawei Technologies, a Chinese telecommunications giant. The investigation suggests that these TSMC-made chips were allegedly passed to Huawei through an intermediary Chinese chip firm. This discovery highlights the challenges faced by the U.S. in enforcing export controls aimed at preventing cutting-edge technology from reaching Chinese companies. Reports indicate that the U.S. efforts to restrict access to high-tech components have not been entirely successful, as evidenced by the incorporation of TSMC technology into Huawei's latest AI chips.
