China Vows Retaliation as U.S. Threatens AI Sanctions Over Model Distillation

Escalation Over AI IP

China's Ministry of Commerce (MOFCOM) has condemned U.S. plans to investigate and potentially sanction Chinese AI firms over allegations of model distillation, calling the threatened moves "lacking factual basis and legal justification" and "typical acts of AI hegemony." Beijing warned it will take "all necessary measures" to safeguard its interests if sanctions proceed.

The dispute marks a shift in U.S.-China tech tensions from hardware restrictions to conflicts over AI model intellectual property. U.S. Treasury Secretary Scott Bessent stated in July 2026 that Washington would examine Chinese open-source models for signs of IP theft and threatened sanctions if theft is established.

The Distillation Debate

Model distillation is a common industry practice where smaller "student" models are trained to mimic larger "teacher" models, often using the teacher's outputs as training data. Anthropic has publicly accused specific Chinese firms—DeepSeek, Moonshot AI, MiniMax, and Alibaba's Qwen—of conducting distillation attacks on its Claude model.

MOFCOM countered that "many US AI companies have used distillation from Chinese models in their research and development and training processes." This assertion was not independently verified. While Chinese models like Qwen, DeepSeek, and Kimi are widely used by U.S. companies, specific evidence of U.S. firms conducting distillation from Chinese models remains unconfirmed.

U.S. Startup Pushback

Nearly 200 U.S. startups, organizing as the Little Tech Association and including companies like Proton and Y Combinator, have urged the U.S. government not to cut off access to Chinese open-source models. The group warned that such restrictions would harm U.S. competitiveness in the rapidly evolving AI sector.

"All Necessary Measures"

Beijing has made clear it will not accept sanctions without a fight. "China will take all necessary measures to firmly safeguard its legitimate rights and interests in response to any actions that substantially harm China's interests," a MOFCOM spokesperson said.

The escalation raises the prospect of a fragmented global AI ecosystem. If the U.S. proceeds with sanctions against Chinese firms for distillation, retaliatory measures from Beijing could disrupt the open-source AI collaboration that many U.S. startups currently rely on.
