The US-China AI notification hotline that Treasury Secretary Scott Bessent unveiled Sunday will take weeks to finalize, according to Trump administration officials, with a working framework unlikely before follow-up talks between Bessent and Chinese vice premier He Lifeng in Shenzhen in two months. President Donald Trump hosts Chinese president Xi Jinping for a state dinner at the White House on Thursday, with executives from OpenAI and Nvidia confirmed to attend and AI at the top of the agenda.
The proposed system, modeled loosely on the Cold War hotline with Moscow, would let each government alert the other to national security incidents tied to frontier AI. Bessent floated the mechanism with He Lifeng on Sunday, but the two sides have yet to agree on the basics — including what kind of incident qualifies as a national security issue and how enforcement would work. China has been noncommittal.
Officials say the goal is a framework that is functional and personally signed off by Trump by the time Bessent returns to Shenzhen in roughly two months. That timing puts formal agreement, at earliest, near the end of the year.
Key facts
- 01Treasury Secretary Scott Bessent announced the US-China AI notification system Sunday with Chinese vice premier He Lifeng.
- 02Trump officials are targeting a functional framework by follow-up talks in Shenzhen in two months' time.
- 03The administration has granted a limited number of licenses this year for Nvidia to sell its H200 chip to China.
- 04Bessent, Howard Lutnick, Michael Kratsios and Sean Cairncross are all in the mix for a new AI czar role; David Sacks is not.
- 05The model for the hotline is the Paulson-Wang Qishan channel credited with easing the 2008 financial crisis.
Several structural pieces remain open. Trump officials have discussed criteria for when each country is obligated to alert the other, and enforcement measures designed to prevent the channel from becoming a one-way US-to-China alert system. Building enforcement with real teeth is the part slowing White House approval, particularly as the administration extends a trade truce and remains reluctant to cut off exports of Nvidia's most advanced chips.
The chip question sits directly alongside the hotline talks. The administration has granted a limited number of licenses this year for Nvidia to sell its H200 chip to China, a part central to training larger AI models. Nvidia's supporters argue that withholding the chips only accelerates Chinese alternatives from Huawei, which by recent accounts has already reached commercial availability with its own AI chips.
Personnel is the other bottleneck. Some officials have suggested the notification system may be delayed until Trump names his next AI czar, envisioned as the head of a new interagency coordination effort informally called an AI Force. Bessent is one of the names in circulation, alongside Commerce Secretary Howard Lutnick and White House AI officials Michael Kratsios and Sean Cairncross.
It is not yet clear whether Trump will pick someone who holds the role alongside an existing cabinet job or someone who leaves their current post to take it. The previous AI czar, David Sacks, held the position as a special government employee.

The push for Bessent rests partly on the analogy to the finance channel that former Treasury Secretary Hank Paulson ran with former Chinese vice premier Wang Qishan during the 2008 financial crisis. Paulson credited that hotline with helping stop China from dumping large holdings of debt issued by Freddie Mac and Fannie Mae. Backers see the AI notification channel as similar in spirit: a direct principal-to-principal line for moments when the normal diplomatic clock is too slow.
Lutnick remains a contender in part because he oversees the Center for AI Standards and Innovation, which handled crises involving frontier AI model companies over the summer. Whichever official gets the job will inherit both the notification framework and the broader question of how the US calibrates chip exports against safety cooperation with a strategic rival.
The gap between announcement and implementation is the story here. A hotline works only if both sides pick up the phone and agree in advance what counts as an emergency; neither piece is settled. The chip-export lever gives Washington leverage in the negotiation but also gives Beijing reason to slow-walk any framework that constrains its own AI buildout. Expect the Shenzhen meeting to be the first real read on whether this channel becomes a working piece of US-China AI policy or another announced structure that never quite ships.
