The U.S. Commerce Department is preparing new restrictions on exports of advanced chips used for artificial intelligence training, according to Reuters. The move would sharpen pressure on semiconductor supply chains tied to Nvidia and Taiwan Semiconductor Manufacturing Co. as Washington seeks to slow China's access to high-end computing hardware.

The proposed curbs would affect shipments to Chinese customers and could ripple through a global chip industry already adapting to years of tightening U.S. controls. Nvidia relies on TSMC and other manufacturers for key components, making the policy shift significant for both companies and their broader supply networks.

The reported measures come amid an escalating technology rivalry between Washington and Beijing, with AI hardware now a central arena of competition. U.S. officials have argued that advanced chips can support military and surveillance capabilities, while industry leaders have warned that expanding restrictions can complicate sales, logistics, and long-term planning.

If finalized, the new rules would add another layer to an already complex export-control regime. For chipmakers, the immediate question is not only how much business could be lost in China, but how quickly they can adjust production and compliance strategies as U.S. policy continues to tighten.
