As the U.S. and China barrel ahead in their quest for AI supremacy, their race could come at the expense of global cybersecurity.Why it matters: The U.S. and China both have an interest in preventing each other from weaponizing AI tools against them or letting rogue systems into the wild. But it remains to be seen whether they can hold a productive dialogue around AI security norms or trust the other to abide by them.Driving the news: President Trump is expected to discuss AI guardrails with Chinese President Xi Jinping in Beijing this week, U.S. officials told reporters Sunday."We want to take this opportunity with the leaders meeting to open up a conversation and see if we should establish a channel of communication on AI matters," one official said.Between the lines: The U.S. is using export controls to slow China's AI progress, but U.S. officials increasingly recognize that the two countries may still need shared rules of the road for how the technology is deployed.Chinese models like DeepSeek are the primary competitors to U.S. models.Advanced AI systems are increasingly viewed in both Washington and Beijing as economic engines, intelligence tools and potential cyber weapons. That makes cooperation harder, but also more urgent.Sixteen business executives, including Elon Musk and Tim Cook, are reportedly joining Trump on the trip — but CEOs from leading AI firms aren't on the list.The big picture: The visit comes as U.S. AI companies wrestle with how to safely release increasingly powerful models that are exceptionally good at finding and exploiting software vulnerabilities.The White House has been embroiled in a monthlong back-and-forth over how to regulate those rollouts, after more than a year of denouncing such regulation.Meanwhile, the White House accused China last month of running "industrial-scale" campaigns to distill and copy American AI models.Yes, but: It's hard for either country to call for restraint around AI-enabled cyber operations when both are actively testing the offensive cyber capabilities of frontier models — potentially to use against each other.In November, Anthropic accused Beijing of using Claude to automate parts of a broader espionage campaign targeting about 30 global organizations. The National Security Agency, which is behind many U.S. espionage campaigns, is already testing out Mythos."The topic is important enough and dangerous enough that we should be having engagement with China on this," Melanie Hart, senior director of the Atlantic Council's Global China Hub and a former State Department official, told reporters.However, the Chinese government used previous meetings on AI safety held under the Biden administration primarily "to gather information about the United States, rather than to be serious about AI guardrails," Hart said.During those talks, Beijing often sent representatives from the foreign ministry who lacked technical AI expertise, she added.What to watch: Don't expect a single visit to reshape U.S. AI policy overnight. Instead, Hart said, the trip is more likely to determine whether future U.S.-China discussions on AI security become substantive or remain largely symbolic."From there, we then need to judge who shows up for the China side," she said. "We want to see the technical experts showing up at the table. That's how we'll know that that's actually real."Go deeper: Trump's legacy week
