Kazakhstan minerals force US hand in AI side-picking letter

The United States is preparing a draft State Department letter that tells roughly 35 countries they must drop competing Chinese AI frameworks or lose access to the American-led Pax Silica coalition and its shared investment projects. Reuters reviewed the undated internal draft and spoke with a U.S. official who said the message is simple: partners cannot have it both ways.

Kazakhstan sits at the center. It is the only nation publicly known to have joined both Pax Silica and China’s World Artificial Intelligence Cooperation Organization, or WAICO. Its reserves of tungsten, copper, rare earth elements and uranium make expulsion costly for Washington, which needs those inputs as much as it wants exclusive alignment.

The letter’s blunt language to 35 signatories

The draft targets the countries that signed the U.S. AI Opportunity Statement in June 2026. That group includes Pax Silica members plus additional partners that signaled willingness to align on AI models, chips and critical minerals. The letter never names China. It refers instead to “duplicative initiatives whose expectations conflict with our own.”

To be part of everything is to be part of nothing. Signature of the Pax Silica Declaration is not merely a membership subscription, but a commitment.

The draft urges recipients to “choose deliberately.” A U.S. official told Reuters the goal is to make clear that countries cannot present themselves as trusted partners in one technology stack while joining an initiative built by China around a competing vision. The State Department declined to comment on “purportedly leaked internal documents.” Reuters could not determine when or whether the letter will be sent unamended.

By framing the choice as one of trust rather than trade, the draft turns a soft coalition into a loyalty test. Partners that treat Pax Silica as one option among several would, under that logic, dilute the shared investment and export-control work the club was built to protect.

China’s embassy in Washington opposed politicizing trade and technology. An embassy spokesperson said such actions “will only stifle global AI advances and serve no one’s interests.” The Kazakh embassy did not respond.

How Pax Silica grew into a supply-chain club

Washington launched Pax Silica in December 2025 as the State Department’s flagship effort on AI and supply-chain security. Under Secretary for Economic Affairs Jacob Helberg has described it as the 21st-century equivalent of oil and steel: “the compute and the minerals that feed it.” The Pax Silica declaration and its supply-chain pillars cover critical minerals, energy, advanced manufacturing, semiconductors, AI infrastructure and logistics. Members gain access to shared investment opportunities in AI-related projects and coordinate on export controls and investment security.

By the second summit in June 2026 the declaration had roughly two dozen signatories. They include close allies such as Japan, Australia, the Republic of Korea, the United Kingdom, Singapore, India, Israel, the European Union, Germany, the Netherlands and Italy, plus newer entrants from Latin America and Central Asia. Taiwan participates as a non-signatory that has endorsed the principles through a separate joint statement. The same June summit produced the broader AI Opportunity Statement signed by the United States and 34 other economies. The full AI Opportunity Statement text and signatory list commits participants to pro-innovation regulation, private-sector mobilization, joint R&D on energy and minerals, and trusted semiconductor ecosystems.

1. December 2025: Washington launches Pax Silica as its flagship AI and supply-chain effort.
2. June 2026: Second summit brings roughly two dozen declaration signatories; the United States and 34 other economies sign the AI Opportunity Statement; Kazakhstan joins as the first Central Asian member.
3. July 2026: China launches WAICO in Shanghai with 29 founding members.
4. Undated draft: State Department letter warns AI Opportunity Statement signatories against competing frameworks.

Pax Silica remains non-binding. The draft letter tries to harden that soft commitment into an exclusive one.

China answers with WAICO and open weights

In July 2026 Chinese President Xi Jinping launched the World Artificial Intelligence Cooperation Organization at the World AI Conference in Shanghai. Twenty-nine countries signed the founding agreement. Membership skews toward Global South and BRICS-linked states; major Western democracies are absent. WAICO promotes China’s open-weight models as a lower-cost alternative to proprietary U.S. systems from companies such as OpenAI and Anthropic. It emphasizes capacity building, technical standards, interoperability and support for developing nations so they avoid a new AI divide.

Beijing has also weighed restrictions on overseas access to some leading Chinese models, tightening the national-security frame even as it courts partners with openness rhetoric. The timing matters: Chinese open-weight systems have posted rapid gains against closed U.S. frontier models, raising the stakes of who controls the training data, compute and mineral feedstocks. That competition already shows up in export patterns and data-centre deals; China’s AI export boom and capacity push has bought Beijing time even while domestic demand remains uneven.

Open weights lower the entry cost for governments that lack large domestic model labs. That pitch lands hardest where budgets are tight and U.S. proprietary systems look expensive. Pax Silica answers with joint investment and trusted supply chains rather than free model weights, so the two offers pull different kinds of partners for different reasons.

Kazakhstan becomes the test case

Washington publicly celebrated Kazakhstan’s accession to Pax Silica in June as the first Central Asian member. Helberg highlighted the country’s critical mineral reserves, its position on the Trans-Caspian Middle Corridor, and plans for joint economic-security work. Kazakhstan also signed the AI Opportunity Statement. Within weeks it joined WAICO as a founding member.

That dual membership set off the alarm that produced the draft letter. Kazakhstan holds substantial reserves of the minerals that feed advanced chips and batteries. Much of its uranium is already contracted to China and Russia, yet its tungsten, copper and rare-earth potential remains strategically valuable to both camps. Analysts note that expelling Kazakhstan would undercut the very mineral diversification Pax Silica was built to achieve. Dual membership therefore functions less as indecision and more as leverage: the country can extract better terms from both sides precisely because neither can afford a clean rupture.

• Uranium: major global supplier, largely locked into existing China and Russia contracts
• Tungsten, copper, rare earths: reserves that matter for chips, magnets and advanced manufacturing
• Geography: Middle Corridor logistics link that both blocs value for non-Russian routes

On X and in policy circles the comparison that landed hardest was the Cold War: could a country sit in both NATO and the Warsaw Pact? Some replies argued middle powers without minerals have no such option; others said Kazakhstan simply proved that usefulness to both sides is itself a strategy.

Minerals, models and the real cost of exclusivity

Pax Silica’s stated aim is to reduce coercive dependencies and partner on the full stack from minerals refining through semiconductors to frontier models and data centers. China has repeatedly used its processing dominance in rare earths as a retaliatory tool in tariff disputes. The U.S. response under President Trump has been to accelerate domestic mining and ally sourcing. Shared investment opportunities inside Pax Silica are the carrot; exclusion is now the stick.

The race itself has tightened. Autonomous hacking capabilities and rapid model improvement have forced governments to treat AI leadership as a matter of military and economic dominance. Forcing partners into a binary choice accelerates a split between a U.S.-aligned closed or controlled stack and a Chinese-led open-weight ecosystem that many developing countries find cheaper and easier to adopt. That split raises costs for everyone who needs both minerals and models. It also hardens the lock-in: once a country builds data centers, standards and training pipelines around one stack, switching becomes expensive.

The pressure falls unevenly. Close U.S. allies with deep security ties (Japan, Australia, South Korea, the UK) face little real choice. Smaller or more distant signatories of the AI Opportunity Statement face a harder calculation: keep symbolic alignment with Washington and risk losing Chinese market access or technology partnerships, or hedge and risk losing Pax Silica investment windows. Countries that control none of the critical inputs have the least bargaining power.

Who absorbs the friction

Fence-sitters without leverage lose first. They may be forced to pick before the letter is even finalized, simply to avoid uncertainty around future project funding and export-control coordination. Mineral holders gain time and negotiating room. China gains a clearer map of who is available for WAICO expansion and open-model diffusion. The United States gains clearer lines of trust for joint projects and controls, at the price of potentially slower mineral diversification if dual members dig in.

• Close allies: deep security ties leave little room to hedge once exclusivity is enforced
• Mineral holders: dual value to both camps buys time and better terms
• Fence-sitters without inputs: weakest hand; pressure arrives earliest around funding and controls
• Private capital: cross-border flows become more political as exclusivity rules harden

The OpenAI and Anthropic model race and data-centre deals already show how quickly capacity and power demand rewrite commercial terms. Government coalitions now sit on top of that commercial race. A forced political choice will feed back into where the next wave of foundries, refineries and training clusters get built.

Private industry is supposed to drive both frameworks. Pax Silica explicitly calls for mobilizing complementary industrial strengths and cross-border capital. WAICO leans on capacity-building programs and open ecosystems. Exclusivity rules make those private flows more political and less efficient.

A Binary Choice Hardens Two Parallel Stacks

If partners must pick one framework, infrastructure follows the political line. Data centers, standards work and training pipelines built around a single stack become costly to unwind. That lock-in is the mechanism behind the draft’s urgency: delay lets dual arrangements harden into facts on the ground.

The U.S. offer bundles investment windows, export-control coordination and a trusted semiconductor story. WAICO bundles lower-cost open-weight models, capacity building and a Global South governance pitch. Neither package is complete without minerals and logistics. That is why a country holding tungsten, copper, rare earths and corridor routes can still bargain while a signatory with none of those assets cannot.

Exclusivity may clarify trust for joint projects. It also thins the bridges between systems that still need each other’s inputs. The draft treats that trade-off as acceptable. Mineral suppliers and model buyers will test whether it holds once letters turn into funding decisions.

The letter still sits unsigned

Nothing has been sent. The draft remains undated and subject to internal discussion. Kazakhstan has not publicly chosen. Other dual or near-dual candidates will watch how Washington handles the one clear case. If the letter goes out largely unchanged, the AI supply chain will look more like two parallel systems with thinner bridges between them. If it is softened, the dual-membership strategy Kazakhstan pioneered may spread. Either way, the hidden stakeholders who control the rocks that feed the chips now sit closer to the center of the contest than the draft’s authors may have intended.
