Chinese startup DeepSeek is among firms invited to brief the U.N. Security Council on artificial intelligence and international security this week, two sources told Reuters, as OpenAI CEO Sam Altman and representatives from Anthropic are also expected to participate in Wednesday’s session.

Plans remain fluid. One source said DeepSeek founder Liang Wenfeng does not plan to attend; other Chinese firms including Moonshot were also invited to make statements. DeepSeek and Moonshot did not immediately comment. The 15-member Council first met on AI risks in 2023, when China warned the technology should not become a “runaway horse” and the United States warned against using AI to censor or repress.

The briefing follows weeks of heightened frontier-lab debate in which some industry leaders urged a coordinated slowdown, warning systems could improve autonomously beyond human control. U.N. Secretary-General António Guterres last week said rapidly advancing AI poses risks that cannot be ignored—putting him at odds with President Trump, who argues existing safeguards suffice and that doubt about AI helps China. Chinese state media have dismissed slowdown calls as a “Cold War playbook” to preserve U.S. dominance. Unlike some U.S. lab chiefs, leaders of China’s top model developers have rarely publicly emphasized catastrophic loss-of-control scenarios and have stayed largely quiet as that debate intensified this month.

Separately, Treasury Secretary Scott Bessent said Monday that senior U.S. and Chinese officials agreed to further AI-safety talks ahead of Trump’s meeting with Xi Jinping later this week. Source concentration is a caveat: DeepSeek’s invitation details rest on Reuters’ exclusive sourcing rather than an on-record company confirmation, while Altman’s expected participation was previously reported.
