China Vows Countermeasures Against US Sanctions Threat Targeting Chinese AI Firms

What happened

China's Ministry of Commerce on July 27, 2026 strongly condemned planned US sanctions against Chinese AI firms, with the US accusing Chinese entities of illegally copying American AI models through distillation. Beijing called Washington's approach "AI hegemonism" and threatened "all necessary measures."

Context and impact

The specific flashpoint is Kimi K3 (2.8 trillion parameters) from Moonshot AI — US officials claim the model improperly extracted capabilities from Anthropic's Fable 5. China dismissed the allegations as lacking factual and legal basis.
