On January 13, 2025, the Biden Administration announced additional restrictions on the export of AI chips and associated technologies. Consequently, 14 Chinese companies were added to the restricted trade list, bringing the total number to 25. Notably, Sophon Technology, a subsidiary of Bitmain, garnered substantial attention due to allegations that it served as an intermediary between Huawei and TSMC. The objective of these measures is to retain advanced computing capabilities within the United States and its allies, thereby preventing other nations from acquiring these critical technologies. The newly introduced regulations classify global countries and regions into three tiers, imposing varying levels of export controls on AI chips. These regulations will come into effect in 120 days.

This action has provoked widespread concern and discussion within the industry. Several prominent American companies, including NVIDIA and Oracle, have voiced their opposition, arguing that such restrictions will hinder global innovation and economic growth, ultimately weakening the United States' global competitive edge. Concurrently, restricted markets, such as China, are actively pursuing technological advancements to address the challenges posed by these new restrictions.
