The U.S. Department of Commerce has deemed the use of Huawei's Ascend processors, specifically the 910B, 910C, and 910D models, a potential violation of export controls due to their reliance on U.S. technology. Concurrently, the Trump administration has rescinded the Biden-era "AI Diffusion Rule," which aimed to impose new export restrictions on AI chips to various countries, including Mexico and Portugal, with stricter measures for China and Russia. These developments align with Donald Trump's visit to Saudi Arabia, where plans for an AI infrastructure using Nvidia chips were announced.
