Treasury Secretary Scott Bessent said the Trump administration will scrutinize open source AI models for intellectual property theft, warning that Washington has the ability to impose sanctions. The remarks come amid growing buzz around Kimi K3, an open source model from China's Moonshot AI, intensifying debate over whether freely released foreign AI models pose a risk to American technology firms and innovation.

The Regulatory Review argues that meaningful transparency from AI labs is essential for any future US-China agreement on artificial intelligence. Without verifiable disclosure of how advanced models are developed and deployed, Washington and Beijing would struggle to build the mutual trust needed for limits on frontier AI. The piece frames openness by companies as a precondition for international AI governance.

The 2026 Global Open-source AI Challenge concluded with its grand finals and awards ceremony held in Hangzhou, China.
