The US is poised to send a blunt diplomatic letter to 35 countries that signed the American AI Opportunity Statement, insisting they choose between joining the US-led Pax Silica alliance or aligning with China’s emerging AI cooperation framework.
- US letter demands exclusive commitment from 35 AI-aligned countries
- Pax Silica coalition aims to control AI supply chains and tech governance
- Kazakhstan's dual membership in US and China groups raises US concerns
What happened
A draft letter reportedly prepared by the US government is intended for the 35 countries that signed the AI Opportunity Statement in June, demanding that they clearly choose to support the US-led AI Partnership for Advanced Computing and Silicon Supply Chain (Pax Silica). The letter uses unusually direct language for diplomatic correspondence, stating that being part of multiple competing initiatives weakens collective effectiveness. It emphasizes that Pax Silica membership involves a binding commitment, not just symbolic association.
The alliance focuses on securing supply chains critical to AI advancement, specifically in AI models, semiconductor manufacturing, and critical minerals necessary for advanced chips. Roughly two dozen nations have formally joined Pax Silica so far, including Japan, Australia, South Korea, and notably Kazakhstan. Concurrently, China has launched its own AI cooperation framework, presenting it as an alternative global AI model ecosystem. The US letter seeks to close the non-binding nature of current commitments by urging participating nations to pick a side.
Why it matters
The letter reflects intensifying geopolitical competition between the US and China over leadership in artificial intelligence technology and supply chains. By requiring exclusive allegiance, the US aims to prevent countries from hedging their bets between the two technological blocs, especially since China has previously leveraged near-monopolies in critical minerals as a geopolitical tool. Kazakhstan’s membership in both frameworks is particularly problematic for Washington given its significant mineral reserves essential for chip production.
This clear-cut choice also highlights the strategic importance of controlling AI platform access and semiconductor technologies amid ongoing US export controls and sanctions aimed at limiting China's AI capabilities. The US coalition offers shared investment opportunities and coordinated export controls, contrasting with China’s approach of distributing open-weight AI models. Both countries are recalibrating their openness to foreign access, intensifying the governance divide in AI.
What to watch next
Key developments to monitor include the timing and final wording of the US letter, which remains undated and could evolve before being sent. The response of the 35 countries—especially European nations, whose participation so far remains unconfirmed—will indicate the global appetite for exclusive alignment in AI governance. Tracking countries like Kazakhstan, which hold strategic mineral resources and have dual memberships, will be crucial for understanding supply chain risks and geopolitical fissures.
Watch also for China’s policy decisions on restricting overseas use of its open-weight AI models as well as US enforcement actions targeting Chinese AI firms and semiconductor imports. The evolving cooperation—or competition—between private sector leaders on AI openness and proprietary technologies will influence how the global AI ecosystem fragments or integrates. These dynamics will define the technological and economic contours of the AI geopolitical landscape in the years ahead.
