Washington may force Kazakhstan to choose between competing US, China AI alliances

The Trump administration is preparing to tell Kazakhstan and 34 other countries that they may have to choose between competing US-backed and China-backed artificial intelligence frameworks as Washington intensifies efforts to shape global technology alliances.
The scenario is outlined in an exclusive report by Reuters. A US official told the news service that partners “can’t have it both ways”.
A draft US State Department letter obtained by the Reuters is addressed to 35 countries that signed the US AI Opportunity Statement in Washington, DC in June. It warns that countries joining the US-led Pax Silica framework would not be able to participate in competing initiatives where the requirements conflict with those of the American framework.
The draft reportedly urges countries to “choose deliberately” and says membership of Pax Silica represents a commitment rather than simply a diplomatic designation. It is reported to state: "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 letter has reportedly not been sent and could still be amended.
First to join
Kazakhstan was the first Central Asian country to join the US-led AI framework. Washington has highlighted the country’s importance as a potential essential supplier of critical minerals used in semiconductors and advanced technologies. However, Astana has also joined China’s World Artificial Intelligence Cooperation Organisation (WAICO). It was launched in Shanghai by Chinese President Xi Jinping in July.
It is thought Kazakhstan is presently the only country signed up to both the US and Chinese frameworks.
The competing commitments present a particular challenge for Kazakhstan. It pursues a multi-vector foreign policy aimed at maintaining relationships with all the major powers while avoiding excessive dependence on any one partner.
Kazakhstan, for instance, maintains strong economic ties with both China and Russia while seeking deeper cooperation with the US and European countries in areas including critical minerals, energy and technology.
The US-China competition over AI has intensified as Chinese open-weight AI models have made advances against proprietary systems developed by US companies including OpenAI and Anthropic, the report noted.
Washington is seeking closer alignment among partner countries partly to limit China’s access to critical minerals, semiconductor technologies and other resources considered important to the development of advanced AI systems.
The draft State Department letter indicates that Washington could increasingly make participation in its technology initiatives conditional on restrictions on cooperation with competing Chinese frameworks. A final US position has yet to be communicated to Kazakhstan.
A report by Tech Times argued that the draft has a major weakness – it does not specify what would constitute a conflicting commitment or what consequences countries would face for refusing to choose. It does not name China, set a deadline or establish a mechanism for determining violations and enforcing compliance, the report observed.
Weak enforcement mechanisms
The potential enforcement mechanism lies in access to advanced chips, the report said. AI accelerators require replacement every few years, creating a recurring dependence on supply channels controlled by the US and its partners. Washington could potentially restrict future chip access through export controls, a mechanism demonstrated in the case of the UAE's G42, which removed Huawei equipment as part of its closer alignment with the US.
However, applying such pressure to Kazakhstan could undermine Washington's objectives, the report argued. Kazakhstan's critical-mineral reserves are a major reason for US interest in bringing the country into Pax Silica, meaning sanctions or an exclusion over its WAICO membership could weaken the supply-chain diversification the framework seeks to promote.
The report also cited China analyst Rui Ma as saying that the approach could ultimately cost Washington more than it gains by encouraging countries to view supply chains as instruments of geopolitical pressure rather than as stable partnerships.
For now, the draft's call to “choose deliberately” remains a political signal rather than an enforceable requirement, the report concluded.
AI shares human tendency to infer character from facial features
Computer-generated images used in the study with questions about trustworthiness. The face on the right is usually seen as more trustworthy by both humans and LLMs.
Human beings have a tendency to infer personality or character traits from other people’s facial features, and these biases—ungrounded in any actual relationship between faces and behavior—lead to unfair outcomes.
Steven Lehr and colleagues explored whether AI models, which are trained primarily on text but have the ability to “see” images, share these biases. The authors asked GPT-4o to make over 4,500 forced-choice judgments between computer-generated faces, and presented thousands of additional forced choices to GPT-5, Gemini 3 Flash Preview, and Claude Sonnet 4.5. In some of the experiments, models were asked to choose which of two faces was more competent or more trustworthy. Other trials used related traits, including asking which face was more confident, smart, hardworking, lazy, inept, careless, warm, helpful, sincere, selfish, hypocritical, or aggressive. Some experiments asked LLMs to judge which computer-generated human face would be more likely to be a serial killer, to be arrested for human trafficking, or to defraud the public using a Ponzi scheme. Finally, LLMs were asked to choose between faces in the contexts of hiring a university president, investing in a tech startup, or selecting a financial manager. In all these cases, the models were willing to weigh in and in the majority of cases chose the same face that a human would typically see as more trustworthy or confident. Across studies, GPT-4o selected the face that would be expected based on human ratings 74.88% of the time. GPT-5 showed notably more bias than its predecessor. When GPT-5 advised on consequential decisions, the model recommended the more competent-looking individual fully 97.04% of the time, as compared to GPT-4o’s 75.19%. Models from other companies produced similar results.
If LLMs were free of human face-to-character bias, they could be used as a tool to help eliminate this form of bias in contexts such as job candidate selection or parole decisions. According to the authors, AI in its present form is instead likely to worsen unfairness if used in such contexts.

With intensifying climate change, decarbonization of the global building sector has become a key priority. A substantial portion of a building’s energy demands consists of heating and cooling needs. Consequently, developing efficient thermal energy storage systems is a crucial part of this effort. Among available options, latent heat thermal energy storage (LHTES) systems that utilize phase change materials offer unique advantages. These include a high energy storage density and the ability to release large amounts of thermal energy at a near-constant temperature, which is crucial for stable thermal management. Indeed, some studies have shown that LHTES systems can reduce heating and cooling energy consumption by up to 45%.
Despite these advantages, accurately modelling and optimizing LHTES systems remains a major challenge. The coupled heat-transfer and fluid-flow processes involved are difficult to simulate accurately. Although physical experiments provide reliable ground-truth data, they are generally limited to laboratory-scale systems. Computational fluid dynamics (CFD) simulations, on the other hand, can capture these complex physical processes across different scales. However, they are computationally expensive and time-consuming, making large-scale design optimization impractical.
In a new study, a collaborative team of researchers from the Republic of Korea, led by Assistant Professor Joo Hyun Moon from the Department of Building Systems Engineering at Hanbat National University in South Korea, has developed a hybrid physics-informed neural network (PINN) framework for optimization of LHTES systems. “The LHTES system utilizes a special wax-type material, called a phase change material, that soaks up a huge amount of heat when it melts and gives it back when it hardens, acting like a battery for warmth,” explains Dr. Moon. “Testing every new design using conventional computer simulations is slow and computationally intensive. In our PINN framework, we teach the AI model the governing laws of physics, enabling it to accurately reproduce the system's behavior and rapidly explore tens of thousands of possible designs.” Their study was made available online on May 05, 2026, and published in Volume 167 of the Journal of Energy Storage on July 30, 2026.
To develop the data-driven PINN, the researchers first created a high-fidelity ground-truth dataset that captures the physics of the LHTES system. For this, they developed a laboratory-scale experimental LHTES setup, and a corresponding CFD model. Experimental measurements were then used to validate the CFD simulations, which showed excellent agreement with only minor deviations. Once validated, the CFD model was used to generate a sparse dataset of 15 high-fidelity simulations that served as training data for the PINN.
The proposed PINN framework employs a zero-dimensional physical model and embeds the system’s governing physical equations directly as loss functions. A key innovation is that the PINN learns case-specific effective heat-transfer coefficients, while geometric effects are captured through a response surface model. By focusing only on discovering the laws of energy conservation, the PINN avoids overfitting despite being trained on sparse data. The response surface model (RSM) then enables the framework to predict heat transfer properties for any arbitrary, unseen geometry and flow condition during the optimization process. Together, the PINN and RSM form a fast digital twin of the LHTES system.
The digital twin is then coupled with a Non-dominated Sorting Genetic Algorithm II (NSGA-II) to perform multi-objective design optimization. The optimization simultaneously searches for designs that maximize total discharged heat and average discharge power while minimizing pumping power.
In numerical experiments, the PINN reproduced the behavior predicted by the CFD simulations with excellent accuracy while enabling rapid, autonomous design optimization. The optimal design obtained using the multi-objective design optimization process performed similarly to the best-performing baseline design, while significantly reducing pumping power. Moreover, the process also shows that flatter pipes are more favorable.
Beyond buildings, the same physics-informed design approach could help improve thermal management in electric-vehicle batteries, data centers, cold-chain logistics, and solar thermal systems. Earlier studies also suggest that smarter control of latent heat storage can cut electricity costs by more than 70%, showing the broader potential of this technology for reducing energy use and emissions.
“Our approach moves the LHTES design process from manual evaluation of discrete cases to autonomous exploration of the entire design space,” concludes Dr. Moon. “It provides engineers with a practical tool for developing more efficient thermal energy storage systems, helping reduce the energy consumption and carbon footprint of buildings while supporting a more sustainable energy future.”

A year ago this week Nvidia became the first company to touch $4 trillion, and MINING.COM ran the numbers against the combined worth of the world’s 50 most valuable mining companies. It was not even close.
The chip designer was worth 2.7 times the MINING.COM TOP 50 (and since valuations quickly shrink outside that, probably twice the entire global mining industry).
This year Nvidia has been having the kind of quarter miners unfortunately know all too well.
After peaking at roughly $5.5 trillion in the middle of May, the stock shed about $1 trillion over the next eight weeks. At the bottom of the slide, Nvidia was briefly trading at 18 times forward earnings – below the S&P 500 average, which made the poster child of the AI age, at least technically, a value stock.
The chipmaker’s P/E is now back near 20 times forward earnings, but mining’s majors change hands for barely 13 – cheaper on next year’s profits than Nvidia managed to look even at its bargain-bin bottom and despite all the criticality clamour surrounding mining.
The scoreboard now reads $5.11 trillion versus $2.19 trillion. Nvidia is worth 2.3 times the top 50 miners, down from 2.7 times last July, and for a few sessions this month the multiple flirted with two – territory last visited when cheap and cheerful DeepSeek gave the AI trade its first proper scare.
Over the past twelve months mining even outgrew the machine – up 47% against Nvidia’s 27% – a first in the short history of this exercise.
But to return to theme of mainstream investors not valuing the production of copper the same way as the production of hallucinations about the production of copper, here’s a sobering thought:
What Nvidia shed between mid-May and early July – nearly five BHPs, and BHP has never been worth more – was about what the whole Top 50 was worth for most of this decade.
Renaming everything critical minerals was a good start (and kudos to met coal and lead for making the list), but it’s time to launch a worldwide public/investor awareness campaign. What about this old nugget for a tagline: If it can’t be grown, it has to be mined.
That includes, for the record, the silicon, copper, gold, silver, tungsten, tantalum, titanium, cobalt, aluminium, tin, nickel, hafnium, ruthenium, molybdenum, indium, palladium, gallium, germanium, arsenic, antimony, bismuth, boron, phosphorus, cerium, lanthanum, yttrium, gadolinium, europium and praseodymium that Nvidia’s chips are made from.
Nvidia Backs 8-GW Ohio AI Campus for OpenAI With $1.5 Billion Investment
Nvidia is backing a massive artificial intelligence infrastructure development in Ohio that could ultimately require at least 10 gigawatts of new power generation, underscoring the rapidly growing impact of AI data centers on U.S. electricity demand.
The chipmaker said it has partnered with SB Energy to secure land, power and data center shell capacity at the PORTS-Pike Technology Campus in Pike County, Ohio, where OpenAI will be the customer under a 20-year lease.
The first phase is designed to provide 4.25 gigawatts of IT capacity, with Nvidia holding an option covering another 3.75 GW. At full buildout, the project would provide 8 GW of AI computing capacity.
SB Energy, which is backed by Japan's SoftBank Group and OpenAI, will build, own and operate the data center infrastructure. Nvidia will exclusively supply the site's AI computing systems, including GPUs, CPUs and networking equipment through its DSX AI factory platform.
The planned scale of the development highlights the increasingly close relationship between AI infrastructure and the energy sector. SB Energy and SoftBank plan to develop at least 10 GW of new electricity generation to support the campus and invest at least $4.2 billion in regional grid infrastructure through a partnership with AEP Ohio.
The companies said the arrangement is structured to prevent the costs of serving the data center campus from being shifted onto existing electricity customers.
Development is expected to proceed in phases beginning in 2028.
The campus is being built around the former Portsmouth Gaseous Diffusion Plant, a major Cold War-era uranium enrichment site in southern Ohio. The developers are working with AEP Ohio as well as the U.S. Departments of Energy and Commerce to redevelop the area into a large-scale technology and power hub.
Nvidia will also invest $1.5 billion directly in SB Energy, joining SoftBank and OpenAI as investors in the infrastructure company. The funding will support SB Energy's broader expansion as demand grows for purpose-built electricity and data center infrastructure serving AI computing.
The project adds to a wave of multibillion-dollar data center developments that are transforming U.S. power demand forecasts. Hyperscalers and AI companies are increasingly seeking dedicated generation, transmission capacity and long-term power arrangements as access to electricity becomes one of the principal constraints on new computing capacity.
The PORTS-Pike development is particularly notable for its scale: 10 GW of generation capacity would be comparable to the output of several large nuclear power stations and represents a major new source of electricity demand concentrated at a single industrial site.
The developers also plan significant local investment. OpenAI has added $40 million to an existing $40 million community benefits fund established by SB Energy, bringing the initial fund to $80 million. The money is intended for programs including energy affordability, workforce development and regional economic development.
The companies said the project could ultimately support tens of thousands of jobs in Ohio.
