What’s the US–China AI ‘hotline’ that Trump plans to pitch to Xi Jinping?

The United States wants a new “notification mechanism” with China to warn each other when an artificial intelligence incident becomes serious enough to threaten national security.

The proposal, effectively an “AI hotline”, was discussed on Sunday during talks in New York between US Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng, ahead of a summit between US President Donald Trump and Chinese President Xi Jinping in Washington this week.

The two leaders are expected to consider establishing a broader US-China dialogue on AI, including the proposed notification system, around which details remain limited.

The initiative comes amid an intensifying contest for AI supremacy between the world’s top two economies, together with increasing warnings from tech giants that guardrails are necessary around the ever-growing technology.

So, what do we know about this so-called hotline, and where is the AI battle between the US and China headed?

US Treasury Secretary Bessent said Washington had proposed creating a US-China AI dialogue, with particular focus on national security and a notification system covering “common goals and common threats”.

“We think that, just like with any cross-border activity, that moving from opaque to more transparency between the number one and the number two AI powers in the world is very important,” Bessent told reporters after Sunday’s discussions.

Trump’s science and technology adviser Michael Kratsios told Fox News on Sunday that the “key thing” Washington wants to discuss is “avoiding shared risks”.
