Chinese customs authorities told customs agents this week that Nvidia’s H200 artificial intelligence chips are not permitted to enter China, according to three people briefed on the matter.
Chinese government officials also summoned domestic technology companies to meetings on Tuesday where they were explicitly instructed not to purchase the chips unless necessary, two of the people and a third source said. “The wording from the officials is so severe that it is basically a ban for now, though this might change in the future should things evolve,” one of the people said.
