China last week added Nvidia’s China-specific RTX 5090D V2 gaming chip to a customs banned list during CEO Jensen Huang’s visit to Beijing alongside US President Donald Trump, the FT reported. The Blackwell-based chip, designed to comply with US export controls, had been used by gamers, animators and AI developers for smaller model training and inference. The banned list initially also included Nvidia’s H200 and H20 AI chips. The move signals Beijing’s push to curb reliance on downgraded Nvidia products and support domestic chipmakers such as Huawei and Cambricon. Despite US approval for H200 sales to firms including Alibaba and Tencent, shipments remain blocked by Chinese customs. Huang said he expects China’s market to eventually reopen to US chip suppliers.
