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.

Nvidia NVDA.O said on Monday it will resume sales of its H20 artificial intelligence chip to China and has introduced a new model tailored to meet regulatory requirements in the Chinese market.

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.
