The Trump administration is threatening sanctions against Chinese AI companies. Here is what the threat means and why it matters.

What happened? Treasury Secretary Scott Bessent said the US could sanction Chinese firms accused of “industrial-scale” theft of American AI technology. The warning follows a September 8 advisory from the FBI, NSA and CISA accusing six Chinese companies, including DeepSeek and Alibaba, of “distillation” — training their models on the outputs of US models like Claude.

What does “distillation” mean? Distillation means a new AI model learns by copying the answers of an existing model instead of training from scratch. Anthropic said it found an organised campaign copying Claude’s behaviour at scale. Bessent summed up the US position in July: “Open source is not open season on American IP.”

What could sanctions do? Sanctions could cut Chinese firms off from US chips, cloud services and partnerships, or put them on the Entity List. That would slow models like Moonshot’s Kimi K3, which reports said is challenging Western leaders.

Why now? Trump is set to meet China’s Xi Jinping later this month. The sanctions threat gives Washington leverage in those talks, as both sides race for AI dominance.
