The worldâs top AI research conference, the Conference on Neural Information Processing Systemsâbetter known as NeurIPSâbecame the latest organization this week to become embroiled in a growing clash between geopolitics and global scientific collaboration. The conferenceâs organizers announced and then quickly reversed controversial new restrictions for international participants after Chinese AI researchers threatened to boycott the event.
âThis is a potential watershed moment,â says Paul Triolo, a partner at the advisory firm DGA-Albright Stonebridge who studies US-China relations. Triolo argues that attracting Chinese researchers to NeurIPS is beneficial to US interests, but some American officials have pushed for American and Chinese scientists to decouple their workâespecially in AI, which has become a particularly sensitive topic in Washington.
The incident could deepen political tensions around AI research, as well as dissuade Chinese scientists from working at US universities and tech companies in the future. âAt some level now it is going to be hard to keep basic AI research out of the [political] picture,â Triolo says.
In its annual handbook for paper submissions, issued in mid-March, NeurIPS organizers announced updated restrictions for participation. The rules stated that the event could not provide services including âpeer review, editing, and publishingâ to any organizations subject to US sanctions, and linked to a database of sanctioned entities. It included companies and organizations on the Bureau of Industry and Securityâs entity list and those on another list with alleged ties to the Chinese military.
The new rules would have affected researchers at Chinese companies like Tencent and Huawei who regularly present work at NeurIPS. The database also includes entities from other countries such as Russia and Iran. The US places limits on doing business with these organizations, but there are no rules around academic publishing or conference participation.
The NeurIPS handbook has since been updated to specify that the restrictions apply only to Specially Designated Nationals and Blocked Persons, a list used primarily for terrorist groups and criminal organizations.
âIn preparing the NeurIPS 2026 handbook, we included a link to a US government sanctions tool that covers a significantly broader set of restrictions than those NeurIPS is actually required to follow,â the eventâs organizers said in a statement issued Friday. âThis error was due to miscommunication between the NeurIPS Foundation and our legal team.â
Before they reversed course, the conference organizers initially said that the new rule was âabout legal requirements that apply to the NeurIPS Foundation, which is responsible for complying with sanctions,â adding that it was seeking legal consultation on the issue.
Immediate Backlash
The new rule drew swift backlash from AI researchers around the world, particularly in China, which produces a large quantity of cutting-edge machine learning papers and is home to a growing share of the worldâs top AI talent. Several academic groups there issued statements condemning the measure and, more importantly, discouraging Chinese academics from attending NeurIPS in the future. Some urged Chinese academics to contribute instead to domestic research conferences, potentially helping increase the countryâs influence in relevant science and tech fields.
The China Association of Science and Technology (CAST), an influential government-affiliated organization for scientists and engineers, said Thursday that it would stop providing funding for Chinese scholars traveling to attend NeurIPS and would use the money instead to support domestic and international conferences that ârespect the rights of Chinese scholars.â
CAST also said it will no longer count publications at the 2026 NeurIPS conference as academic achievements when evaluating future research funding. Itâs unclear if the organization will reverse course now that NeurIPS has walked back the new rule.
