The U.S. Department of Commerce has withdrawn a proposed rule aimed at regulating the export of artificial intelligence (AI) chips. The draft rule, which was under review since late February, was intended to control global access to AI chips and had been circulated among other agencies for feedback. The reason for the withdrawal remains unspecified, and the Department of Commerce has not provided any comments. This development represents a setback for the Trump administration's efforts to overhaul the AI chip export framework established by the Biden administration in January 2025. The proposed rule, known as the AI Action Plan Implementation, included considerations for foreign investment or security assurances related to U.S. data centers as conditions for exporting large quantities of chips. A former official suggested that the withdrawal may indicate internal disagreements over balancing global AI leadership with national security concerns.
