On Tuesday, Treasury Secretary Scott Bessent said the U.S. would examine open source models from China for signs of intellectual property theft, threatening sanctions against Chinese AI companies if IP theft is established.

“We’ve seen a lot of talk about open source models coming and threatening the large language models in the US,” Bessent said on Fox Business Tuesday. “This administration supports open source models, but what we do not support is IP theft. If we see, especially, that overseas models are stealing from our great companies, we have the ability to sanction them because of this theft.”

Bessent’s comments were first reported by Bloomberg.

The statement comes as Chinese models — most recently Moonshot AI’s Kimi K3 — are gaining in capabilities and popularity, threatening to harm the business models of top American AI firms like OpenAI and Anthropic, as well as their abilities to raise more capital to continue developing frontier models.

On Monday, Axios reported that the Trump administration is considering a wholesale ban on Chinese open source models, although others have disputed that claim.
