China bans Nvidia chip during CEO's visit

China has banned an Nvidia gaming chip, the RTX 5090D V2, just as CEO Jensen Huang was visiting the country. This move escalates the ongoing trade and technology war, particularly concerning AI development. The banned chip was a modified version designed to comply with US export controls, but Beijing aims to bolster its domestic chip industry, including companies like Huawei. Despite the ban, Huang expressed optimism about future market access. This development comes as Nvidia prepares to release earnings, which are closely watched as an indicator of the AI infrastructure boom.
