U.S. Threatens Sanctions on Chinese AI Firms Over Model Copying and Chip Access

U.S. officials have escalated pressure on Chinese AI developers by threatening sanctions and launching investigations over allegations that they copied American models and may have illegally obtained advanced U.S. chips. Reuters reported that Treasury Secretary Scott Bessent warned Moonshot could face sanctions after U.S. officials said the Chinese lab distilled its Kimi K3 model from Anthropic’s Fable 5 model, while the Commerce Department is also examining whether Chinese firms accessed restricted U.S. semiconductors for training. The crackdown matters because it deepens the technology fight between Washington and Beijing at a time when both sides are trying to discuss AI safety, and analysts warn the dispute could undermine that dialogue.
