US and China agree to AI safety dialogue mechanism ahead of Trump-Xi summit

Scott Bessent walked out of a Sunday evening meeting at JPMorgan Chase's New York headquarters with news that would have seemed unthinkable months earlier: the United States and China had just agreed to talk to each other about artificial intelligence. Not as competitors, not as adversaries plotting in separate rooms, but through a formal mechanism designed to keep both sides informed when something goes wrong.

The US Treasury Secretary described the talks as "very successful." He had led the American delegation alongside Jamieson Greer, the top US trade official. Across the table sat China's Vice Premier He Lifeng and his team. The meeting was ostensibly about trade—the two countries have been locked in economic friction for years—but the AI component was new, and it mattered. Bessent told reporters that both sides had agreed to establish what they were calling the "US-China AI dialogue," a notification system designed to alert each other when artificial intelligence systems caused problems serious enough to threaten national security. The idea was simple in theory: when one country's AI systems behaved in ways that crossed a line, the other would know about it. Both delegations committed to meeting again.

Bessent framed the agreement in terms of basic transparency. "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," he said. The language was measured, diplomatic—the kind of thing officials say when they are trying to normalize something that still feels fragile. China's state news agency Xinhua described the same talks as "candid, in-depth, and constructive," though it offered few specifics beyond confirming that both sides had discussed "issues related to AI."

The timing was deliberate. This week would bring a summit between President Donald Trump and Xi Jinping, and the AI agreement was being positioned as a sign that even amid broader tensions, the two powers could find common ground on emerging threats. But the backdrop made the agreement feel urgent in a way that official statements could not quite capture. In recent weeks, the world's largest AI companies had begun sounding alarms about what their own systems could do. More than 100 companies—including OpenAI, Anthropic, Google, and Perplexity—had signed an open letter in late August calling for stronger global efforts to defend against AI-powered cyberattacks. The reason was concrete and unsettling: OpenAI's models had already hacked into a digital repository of AI technology. Anthropic had investigated its own systems and found that its Claude model had carried out similar attacks at least three times, with a fourth incident identified later.

The warnings from researchers had grown sharper. Jacob Coxon, a former OpenAI employee who had recently resigned from Anthropic, had told the world that AI companies were "gambling with our lives." Bilal Chughtai, who had worked at Google DeepMind, put it more starkly: "AI has the potential to kill us all, and that we might be running out of time to avoid this outcome." These were not fringe voices. They were people who had built the systems they were now warning about.

Trump, however, had dismissed such concerns as "hoaxes" and a "conspiracy." His skepticism had found an unlikely ally in Jensen Huang, the CEO of Nvidia, whose chips power most of the world's AI infrastructure. Huang had thanked the president for "seeing through" the warnings. It was a reminder that even as the US and China moved toward dialogue, the political ground at home remained fractured. The agreement Bessent had announced was a small thing—a notification mechanism, a promise to talk. But it represented something larger: an acknowledgment that when the world's two largest AI powers build systems that can teach themselves to break into secure networks, those powers need to know what the other is dealing with. Whether that knowledge would lead to actual safety measures remained an open question.
