US Tells 35 Nations: Pick Pax Silica or China’s AI Bloc
3 min readWashington is about to hand 35 partner countries a choice it has avoided making explicit until now: build your AI future on the American stack, or on China’s. A draft State Department letter reported by Reuters warns that signing the Pax Silica declaration cannot be combined with membership in Beijing’s rival framework. Belonging to both is no longer on the table.
What Pax Silica Is
Pax Silica is the US-led framework launched last year to secure supply chains for AI models, semiconductors and critical minerals. It is less a treaty than a club: members align on export controls, chip sourcing and model governance in exchange for preferential access to American technology and the supply lines behind it. In June, 35 countries and regions signed an accompanying AI Opportunity Statement, a softer document that stopped well short of exclusivity.
Then in July, Xi Jinping launched a rival. The World Artificial Intelligence Cooperation Organization is built explicitly around open-weight models, the kind anyone can download and run, and it is open to any country that wants to join. Where Pax Silica offers access on conditions, Beijing’s organization offers access with almost none.
The Ultimatum
The draft letter, addressed to those 35 signatories, warns that Pax Silica membership cannot be combined with duplicative initiatives whose expectations conflict with our own. Joining Beijing’s framework, in other words, could put a country’s place in Washington’s technology and supply chain programs at risk.
The language is unusually blunt for a diplomatic cable. “To be part of everything is to be part of nothing,” the draft reads, according to TNW’s report on the Reuters story. The trigger appears to be Kazakhstan, so far the only country known to have signed on to both initiatives, a precedent Washington seems determined not to let spread.
Why It Matters
Most countries outside the US and China have spent the past two years hedging deliberately: American chips, Chinese open weights, and no public commitment either way. That hedge has been cheap. If the letter goes out as drafted, it stops being cheap.
Watch which governments respond first. Middle powers with large domestic AI programs, including India, Brazil, the Gulf states and much of Southeast Asia, have the most to lose from picking wrong and the most leverage to negotiate. Their answers will say more about where the AI world is heading than any model release this month.
The draft is not final and the State Department has not confirmed it. But the direction is now on the record, and the era of quiet hedging looks close to over.
