Global AI research has split into two separate worlds, and developing countries are choosing to align almost exclusively with China.

Polarization and Integration in Global AI Research

The Takeaway
A geopolitical digital iron curtain is forming in real-time within the scientific community. AI research has polarized around the United States and China, creating two distinct poles of influence. While Western researchers often assume their work is the global standard, the global south is rapidly decoupling from Western networks. This shift is creating an entirely different technological ecosystem that operates outside of US influence. The future of AI will not be a single global standard but a fragmented landscape of competing regional powers.
From the abstract
The AI race amplifies security risks and international tensions. While the US restricts mobility and knowledge flows, challenges regulatory efforts to protect its advantage, China leads initiatives of global governance. Both strategies depend on cross-country relationships in AI innovation; yet, how this system evolves is unclear. Here, we measure the processes of polarization and integration in the global AI research over three decades by using large-scale data of scientific publications. Compa
