The US administration under Trump introduced new rules on April 15 that limit the sale of Nvidia A100 and H100 chips as well as AMD Radeon Instinct MI250X compute cards to China. These measures are aimed at strengthening restrictions against DeepSeek, prohibiting it from purchasing Nvidia chips for AI training and preventing Americans' access to its chatbot. Nvidia announced potential losses of $5.5 billion due to the new restrictions. AMD also reported expected losses in billions of dollars. Since 2022, the US government has been tightening export controls on microchips to China, driven by concerns about Beijing's growing influence in AI and potential national security threats. On April 16, Dutch company ASML announced unwarranted orders for equipment due to new restrictions.
