On top of the world AI research conference, Conference on Neural Information Processing Systems-better known as NeuroIPS-became the latest organization this week to engage with a growing conflict between geopolitics and international scientific cooperation. Conference organizers announced and then quickly reversed new controversial restrictions on international participants. Chinese AI researchers threatening to boycott the event.
“This is a potential moment,” says Paul Triolo, a partner at the consulting firm DGA-Albright Stonebridge who studies US-China relations. Triolo says that attracting Chinese researchers to NeurIPS is beneficial to US interests, but some US officials have pressured US and Chinese scientists to end their work—especially in AI, which has become a sensitive topic in Washington.
The incident could increase political tensions around AI research, as well as prevent Chinese scientists from working at US universities and tech companies in the future. “At some level it will now be difficult to keep basic AI research out of the (political) picture,” Triolo says.
In its annual book of paper presentations, released in mid-March, the organizers of NeurIPS announced updated participation restrictions. The rules stated that the event could not provide services including “peer review, editing and publishing” to any organizations subject to US sanctions, and be associated with database of authorized entities. It included companies and organizations in the Bureau of Industry and Security tool list and those on the other list with them relationship claims to the Chinese army.
The new rules would affect researchers at Chinese companies like Tencent and Huawei who regularly submit work to NeurIPS. The database also includes entities from other countries such as Russia and Iran. The United States imposes restrictions on doing business with these organizations, but there are no rules on academic publication or conference participation.
The NeurIPS handbook has since been updated to specify that restrictions only apply to Specially Designated Citizens and Restricted Personsa list used mainly for terrorist groups and criminal organizations.
“In preparing the NeurIPS 2026 handbook, we included a link to the US government’s sanctions tool which covers a much wider set of sanctions than NeurIPS is required to comply with,” event organizers said. information released Friday. “This error was due to a lack of communication between the NeurIPS Foundation and our legal team.”
Before changing the course, the organizers of the meeting previously he said that the new law was “about the legal requirements that apply to the NeurIPS Foundation, which is responsible for observing the restrictions,” adding that it was seeking legal consultation on the matter.
Immediate disturbances
The new law drew immediate opposition from AI researchers around the world, particularly in China, which produces many of the cutting-edge machine learning papers and is home to a growing pool of the world’s best AI talent. Several academic groups there issued statements condemning the move and, more importantly, discouraging Chinese academics from attending NeurIPS in the future. Others called for Chinese academics to contribute instead to domestic research conferences, which could help increase the country’s influence in the fields of science and technology.
The China Association of Science and Technology (CAST), an influential government organization for scientists and engineers, said Thursday that it will stop providing funding for Chinese academics traveling to attend NeurIPS and will instead use the money to support domestic and international conferences that “respect the rights of Chinese academics.”
CAST also said it will no longer count publications at the 2026 NeurIPS meeting as academic achievement when evaluating future research funding. It is unclear whether the organization will change course now that NeurIPS has backed down on the new rules.
