Extended read
A new regulatory action by the U.S. Department of Commerce has eliminated a key workaround used for exporting high-end AI semiconductors to Chinese entities. The rule change specifically targets shipments to Chinese companies that operate overseas, a channel that had remained open after previous restrictions were put in place. According to the source, this loophole became viable after the 'AI Diffusion rule' was not enforced starting in May 2025. The closure of this channel represents a significant tightening of the US stance on technology transfers to China, with direct implications for the top designers of AI accelerators.
