Pax
Silica launched last December as a State Department framework for locking down the AI supply chain, from critical minerals and semiconductors to data centers and frontier models. Two dozen countries have joined so far, including much of Europe, Australia, South Korea, Japan, and the United Arab Emirates. The
framework outlines trade access to American chips and models alongside capital, manufacturing capacity, and mineral reserves. What the new letter adds is the kind of leverage Washington usually reserves for sanctions regimes. Countries that also sign on with China's answer to Pax Silica, the World AI Cooperation Organization, risk being cut out of much of what America and its partners are building. Beijing launched Waico at last month's World AI Conference in Shanghai with 29 founding members, mostly from the Global South. The organization pitches itself around
open-weight models and capacity building rather than supply chain control, an implicit contrast with the closed model approach coming out of Silicon Valley. For businesses operating across both ecosystems, neutrality may no longer be an option. If Washington carries that logic into export controls and investment rules, a company sourcing rare earths through a Pax Silica partner while selling models into Waico
markets may soon find that its home government has to choose a lane. A Pax before the peaceWashington is asking countries to choose an
order before that order has fully taken shape. Which makes Pax Silica an odd thing to call yourself this early. The older Pax labels generally became attached to eras once their political order was visible. “Pax Britannica” caught on late in Britain's imperial century. “Pax Americana” existed as a phrase in the 1890s, but using it to describe the U.S.-led international order came later. Pax Silica skips that waiting period entirely. Washington gave itself the imperial branding before the coalition had proven it could hold together, and before there was two centuries, or two years, of peace to point to. That's a presumptuous move on its own terms, and it may be a counterproductive one. Analysts in Beijing have been quick to seize on the framing and turn it back on Washington.One researcher
suggested China should let cheap, open models make the case for Waico rather than state pressure. A coalition that has to threaten partners to keep them in the fold, before it has even settled on what its own peace looks like, is a strange one to be borrowing names that took generations to earn. There's a second problem. Historically, a Pax has tended to follow a major war, even if the “peace” that followed was hardly peaceful. Rome's followed decades of civil war.
Britain's followed the defeat of Napoleon. America's emerged from two world wars. Pax Silica is being declared ahead of any of that, over a fight that hasn't actually happened, and the reason may be that neither side can afford to let it start. China dominates the processing of many of the critical minerals advanced technology depends on. The U.S. and its allies control much of the advanced chip and AI stack. Both have already shown a willingness to try and use those
chokepoints as leverage. Each side is holding something the other one needs to function. Pax Silica is an attempt to change that, but for now, this is less a clean split than a standoff, and it makes "pick a side" a strange demand to put in writing when no side in this supply chain can actually stand alone. —Jackie Snow, Contributing
