A U.S. export control regulation that requires semiconductor chip factories to thoroughly vet their customers and treat advanced logic chips as restricted by default should remain in effect and enforcement should be improved, says U.S. Rep. John Moolenaar (R-MI), chairman of the U.S. House Select Committee on China. He wrote that BIS could issue guidance similar to its May 31 guidance concerning entities headquartered in country group D:5 and Macau, clarifying that the worldwide regional stability license requirement remains in effect for exports from front-end fabricators. “This is not a new action — many in the semiconductor industry already appear to have adopted this interpretation — but it would prevent the semiconductor industry as a whole from adopting the highly damaging alternative interpretation… or using it as cover against any future enforcement actions,” wrote Rep. Moolenaar. Alternatively, BIS could publish a rule formally rescinding the AI Diffusion Interim Final Rule to re-establish a separate worldwide license requirement for exports from front-end fabricators, he suggested. “Your plans to grow our enforcement capabilities are necessary and welcome,” Rep. Moolenaar wrote, pointing out that the Chinese Communist Party “will exploit every gap in our export control regime to steal our lead in the AI race, and BIS enforcement officers are the most important obstacles standing in their way.”
