China's leading scientific body, the China Association for Science and Technology (CAST), has decided to boycott the prestigious NeurIPS AI conference after the event initially announced it would reject research from institutions under US sanctions, including several Chinese tech companies. Although NeurIPS later apologized and revised the rules, CAST chose not to reverse its decision, saying it will no longer fund researchers to attend and will reduce the importance of NeurIPS publications in academic evaluations.

Why it matters

The boycott reflects the growing divide between the US and China over technology and innovation, as the two superpowers compete for global leadership in critical fields like artificial intelligence. It also signals that China is increasingly able to stand on its own in advanced AI research and may be less willing to participate in US-led forums if Chinese talent is not fully welcomed.

The details

The NeurIPS conference had initially announced it would reject research from institutions under US sanctions, citing a government list that includes several Chinese tech companies. Although the organizers later apologized and revised the rules, CAST decided to maintain the boycott, saying it will no longer fund researchers to attend the conference and will also reduce the importance of NeurIPS publications in academic evaluations. However, not all Chinese organizations are taking the same stance, as the China Computer Federation accepted the organizers' explanation and did not join the boycott.

  • The boycott decision was announced in April 2026.
  • Last year's NeurIPS conference was held in San Diego, California.

What they’re saying

“This could signal that China is increasingly able to stand on its own two feet when it comes to advanced AI research. It's their way of showing that if Chinese talent isn't appreciated and welcomed at such meetings, China will do more on its own.”

— Rebecca Arcesati, Analyst, Mercator Institute for China Studies

“This sends a clear message: science should not fall victim to politics. If NeurIPS wants to rectify the situation, one possible step would be to publicly reaffirm its commitment to academic neutrality.”

— Yunji Chen, Director, State Key Laboratory of Processors in Beijing

What’s next

The NeurIPS conference organizers may need to take steps to reaffirm their commitment to academic neutrality and ensure that Chinese researchers feel welcomed at the event in the future.

The takeaway

The boycott of the NeurIPS conference by China's leading scientific body reflects the growing tensions between the US and China over technology and innovation. It signals that China is increasingly confident in its own AI research capabilities and may be less willing to participate in US-led forums if Chinese talent is not fully appreciated.
