China Blocks Nvidia H200 AI Chip Shipments Despite US Export Approval

Chinese customs officials have blocked shipments of Nvidia's H200 artificial intelligence chips despite US export approval, causing suppliers to halt production amid supply chain uncertainty. While Nvidia anticipated over one million orders from China, authorities warned domestic firms against purchasing the chips without necessity. It remains unclear if this is a formal ban or a temporary measure, with speculation that China may aim to protect domestic chipmakers or leverage the situation in US-China trade negotiations.
