The Technology Cold War : How the US-China Split Is Creating Two Parallel Internets

In November 2025, four individuals were arrested for smuggling hundreds of Nvidia AI chips to China through Southeast Asian intermediaries. Federal prosecutors described the operation in terms that sounded less like a corporate espionage case and more like nuclear materials smuggling, controlled substances crossing a national security boundary with consequences that extended far beyond the financial value of the hardware involved.

 

That arrest was not a data point. 

It was a signal. 

 

A signal that the technology cold war between the United States and China has crossed from policy documents and trade restrictions into operational reality, a world where advanced semiconductors are treated as strategic weapons, where the internet is fragmenting along national lines, and where the question of which technology stack your company runs on is becoming a geopolitical choice, not just a technical one.

In this blog, I make a specific argument: the bifurcation of the global technology ecosystem into two parallel systems, one centered on the US and its allies, one centered on China’s domestic ecosystem, is no longer a future scenario. 

It is the present reality, advancing faster than most businesses have registered. And the decisions companies make right now about which stack they build on, which cloud they run in, and which AI models they use will have consequences that persist for a decade.

 

Understanding the split requires looking at all four layers where it is happening simultaneously. 

 

Layer One: The Hardware Bifurcation 

Start at the foundation. 

Every AI model, every cloud server, every smartphone, and every autonomous system runs on semiconductors. The country that controls the design, manufacture, and distribution of the most advanced chips controls the infrastructure of the global digital economy. Both Washington and Beijing understand this with a clarity that has not yet filtered into most business strategy discussions.

 

$280B  invested by the US CHIPS and Science Act (2022) to revitalize domestic semiconductor manufacturing and R&D

 

~30%  China’s estimated semiconductor self-sufficiency by 2025 — far below its 70% target under Made in China 2025

 

$450B+  combined AI-specific capital expenditure planned in 2026 by just five US companies: Meta, Alphabet, Microsoft, Amazon, and Oracle

 

The decoupling is most visible and most advanced at the hardware layer. In October 2022, the US imposed sweeping export controls on advanced AI chips and the equipment to manufacture them. The controls were targeted, layered, and specifically designed to deny China access to the most capable semiconductors while maintaining commercial relationships in non-strategic areas.

 

The effect on Nvidia alone illustrates the mechanism. 

 

China accounted for roughly 25% of Nvidia’s data center revenue before the export controls. After the controls, Nvidia designed degraded versions of its chips (the H800 and A800) specifically to fall below the performance thresholds that triggered restrictions. When China banned those chips in retaliation in 2025, it crystallized what many had hoped to avoid: the chip market had bifurcated into two incompatible product lines, each serving a different geopolitical zone.

 

China’s response has been to accelerate “domestic production” with extraordinary urgency. Huawei’s Ascend 910B chip, manufactured using SMIC’s 7nm process, without ASML’s most advanced EUV lithography equipment, is the most concrete evidence that China can produce competitive AI accelerators despite the restrictions. 

It is not yet at Nvidia’s H100 level. 

The trajectory of improvement, combined with the scale of state investment, suggests the gap is closing.

 

The geopolitical supply chain is also reorganizing around Taiwan. 

TSMC, which manufactures the most advanced chips in the world and fabricates chips for both Nvidia and Apple, is building fabs in Arizona ($65 billion committed), Japan, and Germany under sustained US diplomatic pressure. 

Samsung is investing $17 billion in a Texas fab. The physical infrastructure of semiconductor manufacturing is being geographically redistributed away from East Asian concentration toward ‘friendshoring‘; production within allied nations’ borders.

 

“There is no policy that the United States could articulate that would persuade China to abandon its goals of de-Americanization and decoupling in the semiconductor sector. The US should focus less on changing China’s goals and more on making achieving those goals as expensive and complicated as possible.”

— CSIS, December 2025

 

The hardware bifurcation is already largely complete at the highest end. The most advanced AI chips are available in the Western ecosystem or the Chinese domestic ecosystem, not both. 

By 2028, the gap between the two incompatible hardware stacks will be wide enough that the application layer built on top of them will increasingly diverge as well.

 

Layer Two: The Application Bifurcation 

The hardware split is the foundation. The application split is what most people actually experience, and it has been underway for far longer. China has operated a parallel internet ecosystem behind the Great Firewall since the early 2000s, not as a policy accident but as a deliberate architecture.

 

The substitution map is now complete and deeply entrenched:

 

Function	Western Ecosystem	Chinese Ecosystem
Search	Google	Baidu
Social / Messaging	Facebook, Instagram, WhatsApp	WeChat, Weibo, QQ, Xiaohongshu
Short Video	YouTube, Instagram Reels	Douyin (domestic TikTok), Bilibili
E-commerce	Amazon, Shopify	Alibaba (Taobao/Tmall), JD.com, Pinduoduo
Cloud	AWS, Azure, Google Cloud	Alibaba Cloud, Huawei Cloud, Tencent Cloud
Ride-Sharing	Uber, Lyft	DiDi
Payments	Visa, Mastercard, Stripe, PayPal	Alipay, WeChat Pay
Maps / Navigation	Google Maps, Apple Maps	Baidu Maps, Gaode (AutoNavi)
Streaming	Netflix, Spotify	iQiyi, Youku, NetEase Cloud Music

 

What changed in 2025–2026 is the acceleration of this bifurcation beyond China’s borders. 

The TikTok conflict, which began with executive orders in 2020, evolved through multiple ownership negotiations and culminated in a sustained legislative effort to force a sale or ban, established a precedent that no major Chinese-owned application can operate in the US market without structural ownership and data separation.

 

China’s response was symmetrical. 

 

The Cyberspace Administration of China (CAC) mandated in February 2026 that social media platforms censor content deemed to spread ‘fear of marriage’ or ‘anxiety about childbirth’, a routine example of the ongoing expansion of content controls that make Chinese platforms operationally incompatible with Western free expression norms. 

These are not converging systems. They are diverging systems, with each side’s regulatory requirements making the other’s platforms operationally untenable.

 

The ‘splinternet‘ , a term coined by internet governance scholars to describe the fragmentation of the global open internet into distinct regional networks is no longer a warning. 

As Foreign Policy put it as early as 2020, the actions were accelerating the consolidation of the internet into at least three separate regions centered on the US, China, and the EU. That consolidation has now advanced to the point where most observers treat it as a fact rather than a risk.

 

Layer Three: The AI Model Bifurcation 

This is the newest and most consequential layer of the split. 

As AI models move from research tools to core infrastructure, powering search, enterprise software, autonomous systems, and consumer products, the question of which AI model underlies a given product becomes a question of geopolitical alignment.

In January 2026, DeepSeek, an open-source large language model developed by a Chinese AI lab, briefly topped Apple’s App Store charts globally and demonstrated performance competitive with OpenAI’s GPT-4o at a fraction of the reported training cost. 

 

The response in Washington was immediate: a lawmaker introduced the ‘Decoupling America’s Artificial Intelligence Capabilities from China Act.’ The University System of Georgia placed DeepSeek on a prohibited applications list alongside TikTok and WeChat.

 

The CSIS analysis put it plainly: the current AI race between the US and China is analogous to the Cold War space race, but operating at an incomparably larger scale.

 

The model bifurcation has practical implications that go beyond geopolitics. 

 

An enterprise deploying an AI agent that uses DeepSeek in the US faces regulatory uncertainty. An enterprise in China deploying a system built on GPT-4 faces similar exposure. The compliance pressure from both directions is pushing enterprises toward domestic AI stacks, which means different models, different capabilities, different data training, and ultimately different outputs for the same queries.

 

“Unlike the space race, which was a competition between two governments, the AI race involves private companies spending more in a single year than the entire Apollo program cost over a decade. The strategic stakes are the same. The scale is unrecognizable.”

— CSIS, December 2025

 

China’s AI stack is not a pale imitation of the Western one. 

 

Baidu’s ERNIE Bot, Alibaba’s Tongyi Qianwen, Huawei’s Pangu, Tencent’s Hunyuan, and ByteDance’s Doubao are all large-scale foundation models with significant domestic user bases. 

They are trained on different data, optimized for different use cases, and subject to different governance requirements. The Chinese government’s AI governance framework requires that AI models operating in China align with ‘core socialist values‘ in their outputs. 

This is not a fringe requirement; it is enforced, and it means that a model trained in China cannot produce the same outputs on politically sensitive topics as one trained in the US.

 

Two intelligences. 

Two datasets. 

Two governance frameworks. 

Two incompatible alignment requirements. 

 

The AI model layer is where the technology cold war becomes most philosophically profound, because it is not just the infrastructure that is bifurcating. It is the machine layer that mediates human access to information.

 

Layer Four: The Financial Infrastructure Bifurcation

The least discussed and potentially most consequential layer of the split is financial infrastructure. 

While the hardware, application, and AI model bifurcations are visible and widely covered, the financial technology bifurcation is advancing quietly and will have the most durable long-term consequences.

 

China’s digital payment ecosystem — Alipay and WeChat Pay, is more advanced than anything deployed in the Western world in terms of consumer adoption and integration depth. 

Both platforms function as ‘super apps‘ that integrate payments, social media, government services, ride-sharing, and financial products into a single interface. Between them, they process the majority of China’s retail transactions. 

 

Visa and Mastercard have minimal penetration in the domestic Chinese market.

In parallel, China has been developing the digital yuan, “the e-CNY”, as a state-issued central bank digital currency. 

 

The e-CNY is not designed to replace Alipay and WeChat Pay domestically. Its strategic purpose is different: to enable cross-border transactions that bypass the SWIFT network and reduce dependence on dollar-denominated settlement infrastructure. 

Every cross-border trade settled in e-CNY rather than dollars is one less transaction flowing through the Western financial infrastructure stack.

 

The Western financial technology response has been the stablecoin infrastructure surge documented elsewhere, Stripe acquiring Bridge for $1.1 billion, Mastercard acquiring BVNK for $1.8 billion, and Visa settling in USDC. 

The stablecoin ecosystem is dollar-denominated and US-infrastructure-native. As it scales, it reinforces dollar settlement infrastructure. 

As the e-CNY scales internationally, it builds an alternative. The financial technology bifurcation is the US-China technology cold war expressed in payments.

99% of stablecoin supply is USD-pegged. 

The geographic adoption of dollar-denominated stablecoins in emerging markets, Vietnam, Argentina, Nigeria is simultaneously an organic response to local currency instability and a structural extension of dollar financial infrastructure. 

The technology cold war is being fought in payment rails as much as in chip fabs.

 

The Countries Caught in the Middle, and Why Their Choice Matters?

The technology cold war is framed as a bilateral conflict between the US and China. 

The reality is that the most consequential decisions are being made by the countries in between, and their choices will determine whether the splinternet hardens into two permanent blocs or remains permeable.

 

South Korea’s situation is the most structurally revealing. 

Samsung Electronics and SK Hynix are the world’s dominant memory chip manufacturers. Both companies rely on US semiconductor equipment and technology under export control restrictions, while maintaining significant revenue from the Chinese market. 

South Korea cannot fully align with either bloc without catastrophic economic consequences on one side or the other. As one analyst summarized the Korean dilemma in March 2026: resilience now means embedding geopolitical diversification in the operational plan, not just sales targets.

 

India’s position is strategically different. 

The US has brought India into the Pax Silica alliance; the informal coalition of nations being integrated into the US-aligned semiconductor supply chain through the CHIPS Act diplomacy, AUKUS, and bilateral technology agreements. 

India’s semiconductor ambitions, combined with its massive engineering talent base and its strategic interest in not being dependent on either the US or China, make it the most significant swing factor in how the technology cold war resolves.

 

Vietnam, Taiwan, Japan, and the Netherlands all occupy critical positions in the supply chain that neither bloc can easily replicate. TSMC’s continued existence as the world’s leading chip manufacturer makes Taiwan the single most geopolitically important piece of real estate in the technology cold war. The Taiwan Semiconductor question is not just a geopolitical flashpoint, it is the point where the hardware bifurcation is most fragile.

 

For countries in the Global South, and specifically for the tech ecosystems developing in Pakistan, Southeast Asia, and Sub-Saharan Africa, the splinternet creates a forced choice that most policymakers are not yet treating with the seriousness it deserves. 

 

Building on US cloud infrastructure with US AI models means aligning with one bloc. Building on Alibaba Cloud, Huawei, or DeepSeek means aligning with another. The choice of technology stack is becoming a foreign policy decision that most governments are making by default rather than by design.

 

Where Decentralized Infrastructure Fits in a Bifurcating World?

The technology cold war creates a structural problem for any infrastructure that depends on cross-border interoperability. National cloud providers, nationally-approved AI models, and national payment systems all fragment as the two blocs harden. This is, paradoxically, the moment when decentralized, borderless infrastructure becomes most strategically relevant.

Blockchain networks are by design jurisdiction-neutral. 

Bitcoin validates transactions identically in Shanghai and San Francisco. Ethereum smart contracts execute the same code regardless of the political relationship between the parties.

 

USDC transfers settle on Solana without routing through any national banking system. The same properties that made blockchain seem like a niche technology in a globalized world make it genuinely useful in a world where national borders are reasserting themselves over digital infrastructure.

 

This is not an abstract argument. 

 

The Allium data showing 45% of stablecoin payment volume is intra-APAC and growing faster than cross-border flows reflects the practical consequence of stablecoin infrastructure providing dollar settlement capabilities in markets where traditional Western financial infrastructure has limited penetration, and where the e-CNY is the alternative on offer.

 

The post-quantum cryptography challenge adds another dimension. 

Both the US and Chinese technology stacks will need to migrate to quantum-resistant cryptography as quantum hardware matures. Blockchain infrastructure that builds post-quantum resistance into its cryptographic layer now, rather than retrofitting it later, will be more resilient across both geopolitical blocs than infrastructure that inherits its cryptographic dependencies from national standards bodies that are themselves in conflict.

 

The practical implication for Web3 builders: decentralized infrastructure is not just a philosophical preference in the technology cold war era. It is a structural hedge against a world where choosing US or Chinese cloud infrastructure commits you to one geopolitical bloc or the other. A protocol that runs on distributed nodes across jurisdictions, settles in a neutral digital currency, and encrypts with standardized post-quantum cryptography is, by design, less exposed to the technology cold war than one built on either bloc’s proprietary stack.

 

The Directional Call: Where This Ends and What It Means for Your Company

Three scenarios for how the technology cold war resolves, in order of likelihood:

 

Scenario 1: Managed Bifurcation (Most Likely, 2026–2035)

 

The two blocs harden but remain economically interdependent in non-strategic sectors. 

 

Companies operate ‘dual stack‘: maintaining US-aligned and China-aligned technology implementations for different markets. The cost of this duplication is high but manageable for large enterprises. 

Smaller companies effectively choose one market or the other. The internet remains technically interconnected through physical infrastructure but operationally divided by regulatory requirements, content controls, and AI governance frameworks.

 

This scenario is already underway. 

Microsoft has a China-specific Bing. 

Amazon has a China-specific site. 

ByteDance operates TikTok and Douyin as legally and technically distinct entities. 

 

The dual stack model is not a future possibility; it is the current adaptation strategy of every multinational technology company.

 

Scenario 2 : Competitive Coexistence (Possible, with Negotiated Boundaries)

 

Both sides establish negotiated boundaries for technology decoupling, advanced AI chips and military-relevant technologies remain restricted, while consumer and commercial applications maintain cross-border access under data sovereignty frameworks. This scenario requires sustained diplomatic engagement and formal technology governance agreements that do not currently exist.

The structural obstacle to this scenario is that neither side has defined ‘emerging and foundational technologies‘ narrowly enough for the other to trust the boundaries. The CSIS analysis is explicit: no US policy change would convince China to abandon de-Americanization goals. The decoupling will continue regardless of the diplomatic temperature.

 

Scenario 3 : Hard Decoupling (Low Probability, Catastrophic Consequences)

 

A Taiwan conflict, a major cyber attack on critical infrastructure, or a severe escalation of export controls triggers a complete severance of technology ties. 

In this scenario, global supply chains fragment catastrophically, the global economy contracts significantly, and the two technology blocs become genuinely incompatible. Most analysts consider this scenario unlikely because its economic consequences would be devastating for both sides simultaneously. But ‘unlikely’ is not ‘impossible,’ and the risk is not zero.

 

What Companies Should Actually Do?

 

The managed bifurcation scenario, the most likely one, has direct operational implications for any company building technology products in 2026.

 

• Audit your technology stack for geopolitical dependencies. Which cloud provider hosts your infrastructure? Which AI model powers your product? Which payment processor handles your transactions? Each answer positions you in one bloc or the other, with consequences for market access in the opposing bloc.

 

• Design for modularity. The companies that will navigate the managed bifurcation most successfully are the ones that have architected their systems to swap AI providers, cloud regions, and payment processors without rebuilding from scratch. The technical term is ‘vendor agnosticism.’ The strategic term is ‘geopolitical resilience.’

 

• Decide your markets deliberately. Most companies cannot afford to build and maintain fully separate technology stacks for both blocs. The practical decision is which market to prioritize and to make that decision explicitly rather than inheriting it from default technology choices.

 

• Take decentralized infrastructure seriously. For companies whose products depend on cross-border interoperability, payments, data sharing, identity verification, financial settlement — blockchain-native infrastructure provides a jurisdiction-neutral alternative to the increasingly fragmented national cloud and payment stacks.

 

• Monitor the standards war. Both the US and China are actively lobbying to have their technology standards adopted by international bodies; 5G protocols, AI governance frameworks, and data localization requirements. The standards that prevail in each sector will determine which technology products can be sold globally and which are confined to one bloc. This is not a passive background condition. It is an active, competitive dynamic with direct commercial consequences.

 

The Internet Was Never Really One Thing, Now Everyone Knows It.

The global internet was always a political construction as much as a technical one. 

The TCP/IP protocols that made it work were developed by US defence research institutions. The governance bodies that managed domain names and IP addresses were headquartered in California. The companies that built the dominant platforms were American. 

The currency that denominated most transactions was the dollar.

 

China recognized this earlier than most. 

The Great Firewall was not paranoia, it was a rational response to the recognition that operating on Western digital infrastructure meant operating on Western terms. 

The domestic ecosystem China built in response, at enormous initial cost and friction — is now the most complete alternative digital economy on earth.

 

What is new in 2026 is that the US has recognized it too. 

The export controls, the CHIPS Act, the TikTok legislation, the AI chip restrictions, and the Pax Silica alliance are all expressions of the same realization: technology infrastructure is geopolitical infrastructure, and geopolitical infrastructure requires geopolitical management.

 

The splinternet is not an accident. 

It is not a failure of diplomacy or a missed opportunity for cooperation. It is the logical endpoint of two nations with incompatible governance philosophies, incompatible value frameworks, and incompatible strategic interests, both recognizing that technological supremacy is the primary currency of twenty-first century power.

 

The internet you grew up with, open, global, governed by consensus, aspiring to universality, was an artefact of a specific historical moment that is ending. What replaces it will be determined not by technologists, but by the decisions that companies, governments, and builders make right now about which stack to build on, which values to embed, and which version of digital sovereignty to defend.

 

That is not a comfortable conclusion. 

It is, however, an accurate one.

Frequently Asked Questions (FAQs)

 

What is the ‘splinternet’ and is it already happening?

It’s the fragmentation of the global internet into separate regional networks with different platforms, rules, and standards. And yes, it’s already here. China has operated behind the Great Firewall for two decades. The TikTok legislation and AI chip controls are now accelerating it from the Western side, too. A user in China and a user in the US are experiencing fundamentally different internets today.

Why are semiconductors the central battleground in the US-China technology war?

Because whoever controls the most advanced chips controls the most capable AI, the most capable weapons, and the most capable economy simultaneously. The US controls chip design tools and manufacturing equipment. China controls rare earth minerals. Neither can build the future without what the other holds. That’s why this fight is structural, not transactional.

What does DeepSeek’s success mean for the US-China AI competition?

It means the export control strategy has limits. China produced a model competitive with US frontier AI using restricted hardware through algorithmic efficiency rather than raw compute. The response in Washington was immediate: new legislation, new bans, new panic. That reaction tells you everything about how seriously the threat is being taken.

How does the technology cold war affect companies that are not in the US or China?

You’re being forced to choose a side; most companies just haven’t realized it yet. Your cloud provider, your AI model, your payment processor, each one positions you inside one bloc’s regulatory environment. South Korea, India, and Vietnam are all navigating this in real time. The companies making this choice deliberately will be better positioned than those making it by default.

What is the role of blockchain and Web3 in the technology cold war?

Blockchain is the only major infrastructure layer with no national headquarters. A USDC transfer on Solana doesn’t route through SWIFT or the e-CNY system. Bittensor and Render provide GPU compute with no national cloud affiliation. In a world where every infrastructure choice is becoming a geopolitical alignment, jurisdiction-neutral rails are no longer just philosophically interesting; they’re strategically useful.

Is the global internet actually splitting into three parts: the US, China, and EU?

Yes. The EU’s regulatory stack; GDPR, DSA, DMA, and AI Act, creates compliance requirements incompatible with both the US commercial model and the Chinese sovereign model. Any company selling globally is already maintaining three separate product implementations, whether they’ve named it that or not. The three-bloc internet isn’t coming. It’s the current operating reality for every multinational tech company.
