China's largest science federation announced a boycott of NeurIPS, a top AI conference, after it banned submissions from US-sanctioned entities like Huawei and SMIC. The China Association for Science and Technology will redirect funding to domestic conferences and stop recognizing NeurIPS papers in its programmes, escalating tensions between the US and China over cutting-edge AI research.

China Boycott Targets Premier AI Conference Over Sanctions Policy

The China Association for Science and Technology (CAST), China's largest federation for science and technology professionals, announced a formal China boycott of the Conference on Neural Information Processing Systems (NeurIPS) on Friday

1

. The decision follows a policy change by the California-based foundation running the AI conference that implements a ban on papers from US-sanctioned entities, effectively blocking Chinese tech companies like Huawei and SMIC from submitting research papers

2

. NeurIPS enacted the new policy earlier this week to comply with US sanctions laws, sparking immediate outrage in China as the two nations compete to develop the most advanced AI models.

CAST Announces Sweeping Measures to Redirect Support to Domestic Conferences

CAST's response includes multiple concrete actions that reshape how Chinese researchers engage with the global scientific community. The organization will stop accepting funding applications for members wanting to attend NeurIPS and will redirect support to domestic conferences or "international conferences that respect the rights and interests of Chinese academics," according to its official statement

3

. Additionally, papers accepted at NeurIPS will no longer be recognized as qualifying research outputs for its funding programmes, though CAST will still acknowledge their academic impact if evaluated by Chinese academic societies

4

. This policy shift affects how Chinese researchers can advance their careers and secure institutional support.

Geopolitical Tensions Between the U.S. and China Fracture Scientific Collaboration

The escalating conflict highlights how geopolitical tensions between the U.S. and China now directly impact cutting-edge AI research and technology development. NeurIPS provides a crucial forum for researchers and companies worldwide to submit peer-reviewed research, discuss the latest breakthroughs in AI, and recruit top talent in the industry

1

. The ban means previous Chinese sponsors of the conference, such as Huawei, are now excluded from submitting research papers. Washington has imposed US sanctions on hundreds of Chinese universities and companies in recent years, preventing them from legally acquiring advanced US technology, while also increasing scrutiny on Chinese scientists at US universities over alleged ties to entities in mainland China

Implications for Frontier Technology and AI Development

Both nations are attempting to use state power to influence each other's frontier technology capabilities, creating a fragmented landscape for scientific collaboration

3

. China has also tightened its regulatory approach, reportedly barring two executives of AI agent startup Manus from leaving the country as regulators review whether Meta Platforms' $2 billion acquisition of the Chinese-founded firm violated investment rules

4

. This tit-for-tat dynamic threatens to bifurcate the global AI research ecosystem, potentially slowing innovation as researchers lose access to diverse perspectives and findings. Watch for whether other countries' scientific organizations follow CAST's lead, and whether alternative international venues emerge to fill the gap left by NeurIPS's exclusionary policy. The semiconductor and supply chains sectors face similar pressures as both nations compete for dominance in frontier technology.
