When AMD CEO Lisa Su arrived in China last week just days after Nvidia's CEO left, she kept a much lower profile than Jensen Huang, who drew crowds in the centre of the capital as he posed for photos and ate local ‌delicacies like Beijing-style soybean paste noodles. Just a year ago at the annual Computex trade show in Taipei, Huang said Nvidia's market share in China had dropped to 50% from 95% due to U.S. export controls. Since then, that ​has effectively fallen to zero, he said this year, amid Beijing's push for self-reliance in advanced AI chips.
