By Liam Mo, Anne Marie Roantree and Che Pan BEIJING/HONG KONG (Reuters) -Chinese firms are scrambling to buy Nvidia H20 artificial intelligence chips, two sources told Reuters, as the company said it plans to resume sales to the mainland days after its CEO met U.

Data center operators in China, which use Nvidia’s H20 chips to crunch data for various AI services, have been struggling to find a local alternative that is as good as the U.S. company’s chips.

Washington has been concerned China could use Nvidia’s chips to get a jump on the U.S. in high-tech fields, particularly when it comes to artificial intelligence.
