US Gives 35 AI Partners an Ultimatum: Drop China's Framework or Lose Access

For AI builders and researchers, the unit of analysis is shifting from model performance to geopolitical alignment. The U.S. State Department's draft ultimatum to 35 AI Opportunity Statement signatories means a lab's access to critical minerals, advanced chips, and model-training collaboration may soon hinge on which national framework its government belongs to — not just the quality of its research.

The United States is preparing to formalize a two-bloc structure for global artificial intelligence. According to a U.S. official and an internal State Department draft letter reviewed by Reuters, Washington plans to tell dozens of partner countries they must choose between the U.S.-led Pax Silica framework and China's rival World Artificial Intelligence Cooperation Organization (WAICO) — and that continued membership in Beijing's initiative will mean exclusion from American AI supply chains. The draft is addressed to the 35 signatories of a U.S. "AI Opportunity Statement" signed in June 2026, a group that includes members of the non-binding Pax Silica framework and other governments that had signaled a desire to align AI cooperation with Washington. This is a decisive shift from coalition-building by invitation to alignment by ultimatum.

"AI Opportunity Statement" signed in June 2026, a group that includes members of the non-binding Pax Silica framework and other governments that had signaled a desire to align AI cooperation with Washington.

Pax Silica, launched by Washington in 2025, was designed to secure supply chains for AI models, semiconductors, and critical minerals at a moment of intensifying technological rivalry with Beijing. Roughly two dozen countries have joined, including close U.S. allies Japan, Australia, and South Korea, as well as Kazakhstan — a prospective source of critical minerals that has also signed on to China's coalition. The State Department letter is blunt about the consequences of hedging: "To be part of everything is to be part of nothing," it reads, adding that signature of the Pax Silica Declaration "is not merely a membership subscription, but a commitment." Countries are urged to "choose deliberately," and the letter warns the commitment "cannot be held alongside membership in duplicative initiatives whose expectations conflict with our own" — without naming China directly.

The trigger for this escalation is partly structural and partly specific. In July 2026, Chinese President Xi Jinping launched WAICO, promoting China's open-weight model technology as a direct challenge to U.S. influence over the fast-moving AI sector. Beijing's pitch — open, accessible, and sovereignty-friendly AI — is designed to appeal to developing and middle-income nations that lack the capital or compute to build their own frontier models. Kazakhstan, the only country so far known to have joined both initiatives, has become the test case, setting off alarm bells in Washington about the permeability of the U.S. framework. By pressing countries to choose, the U.S. hopes to starve China of the resources — critical minerals, semiconductor fabrication capacity, and model-training collaboration — needed to build the most sophisticated AI, which American officials frame as a matter of military and economic dominance.
