A new report titled Tightening the Net: China’s Infrastructure of Oppression in Iran paints a chilling picture of how one of the world’s most sophisticated systems of digital control is being exported and adapted to serve another authoritarian regime. Produced by ARTICLE 19, the report details a deep and evolving partnership between China and Iran that is reshaping how power is enforced, dissent is crushed, and entire populations are monitored.

At the center of this analysis is a stark conclusion. China’s model of digital authoritarianism is not staying within its borders. It is being actively replicated, refined, and deployed in Iran to build what amounts to a full-spectrum surveillance state.

ARTICLE 19 is an international organization focused on defending freedom of expression and access to information. Through research, advocacy, and policy work, it tracks how governments restrict speech and control digital spaces.

According to the report, Iran has embraced China’s approach not just in theory but in practice. Michael Caster, who leads the organization’s Global China Programme, put it bluntly. “In its pursuit of total control over the digital space, Iran borrows directly from the Chinese digital authoritarian playbook.”

That playbook is not abstract. It is built on systems of censorship, surveillance, and centralized control that allow governments to shape what people see, say, and even think. In Iran, these systems are now being deployed with growing sophistication and force.

A Brutal Test Case in Real Time

The consequences of this cooperation became visible during the protests that erupted across Iran beginning in late December 2025. Sparked by economic hardship and longstanding grievances, the demonstrations quickly turned into a nationwide challenge to the regime.

The response was devastating. Estimates cited in the report suggest that as many as 30,000 people may have been killed (figures have since been updated, some estimates as high as 100,000), with countless others arrested. At the same time, the government moved aggressively to control the flow of information.

By early January 2026, Iran imposed a near total shutdown of internet, phone, and mobile networks. This was not a simple blackout. It was a coordinated, multi-layered operation that demonstrated an unprecedented level of control over national infrastructure.

Satellite internet systems, including Starlink, were disrupted at scale. Up to 80 percent of traffic was reportedly blocked using advanced interference techniques. Authorities also deployed drones to locate and confiscate satellite equipment, while criminalizing possession with penalties of up to ten years in prison.

This level of control did not emerge overnight. It reflects years of investment, much of it supported or inspired by Chinese technology and strategy.

The Architecture of Digital Control

At the heart of Iran’s system is its National Information Network, or NIN. This project is designed to replicate many of the functions of China’s Great Firewall by creating a controlled domestic internet that can operate independently from the global web.

The goal is simple but profound. Limit access to outside information, centralize control, and embed surveillance deep into the system itself.

The report makes clear that this is not just a parallel development. It is a direct adaptation. Iranian officials have repeatedly cited China’s model as an inspiration, praising its ability to maintain control over digital spaces.

Mo Hoseini of ARTICLE 19 explains the implications. “Emulating China’s infrastructure of oppression helps Iran entrench power, sidestepping accountability and exercising full control over the information environment. That way, dissent is not just silenced, it is prevented from ever surfacing.”

This is the essence of digital authoritarianism. It is not merely about reacting to dissent. It is about preventing dissent from forming in the first place.

Institutions Built for Control

The partnership between China and Iran extends beyond technology into the structure of governance itself. Iran’s Supreme Council of Cyberspace closely mirrors China’s Cyberspace Administration of China.

Both institutions operate under centralized leadership, with authority over censorship, surveillance, and internet policy. In Iran, the council is chaired by Supreme Leader Ali Khamenei and integrates executive, legislative, judicial, military, and intelligence functions into a single body.

This level of consolidation allows for rapid decision making and unified enforcement. It also removes checks and balances that might otherwise limit abuse.

China’s Cyberspace Administration has served as a blueprint. Its evolution into a powerful central authority reflects the priority placed on controlling digital space. Iran’s adoption of a similar structure signals alignment not just in tactics but in philosophy.

Both systems are grounded in the concept of “cyber sovereignty,” the idea that governments have absolute control over their domestic internet. This principle directly challenges the concept of a free and open global internet.

The Technology Behind the Crackdown

The tools of repression are both sophisticated and extensive. Chinese companies have played a key role in supplying these capabilities.

Firms such as ZTE, Huawei, Tiandy, and Hikvision have provided surveillance and monitoring technologies that allow Iranian authorities to track communications and control information flows. These technologies include systems capable of monitoring voice calls, SMS messages, email, and internet traffic.

One of the most powerful tools involved is Deep Packet Inspection. This technology allows authorities to analyze and filter data as it moves across networks, making it possible to block content, identify users, and track behavior in real time.

Despite international sanctions, these companies have continued to operate in Iran, often through front companies designed to obscure their involvement. This has made accountability difficult and allowed the transfer of technology to continue.

The result is a surveillance ecosystem that is both expansive and deeply embedded.

A System Near Completion

By the time the recent protests erupted, Iran had already made significant progress in building this system. The near total shutdown of communications demonstrated just how far the infrastructure had advanced.

The ability to control not only internet access but also banking, healthcare, and emergency services highlights the depth of integration. This is not just about censorship. It is about controlling the fundamental systems that people rely on to live and communicate.

The report suggests that Iran is now capable of exercising a level of digital control that rivals the most advanced authoritarian systems in the world.

The Broader Threat to Freedom

What makes this development particularly alarming is not just its impact within Iran. It represents a model that can be exported and replicated elsewhere.

The partnership between China and Iran is part of a broader trend described in the report as “networked authoritarianism,” involving countries such as Russia and North Korea. Together, they are developing and sharing tools that enable governments to suppress dissent and control populations with increasing precision.

This raises profound questions about the future of the internet and the global balance between freedom and control.

The report calls for urgent action, including targeted sanctions on companies involved in supplying these technologies, greater transparency in technology transfer, and increased support for tools that allow people to bypass censorship.

It also emphasizes the need to defend the principle of universal human rights in digital spaces.

The picture that emerges from Tightening the Net is stark. China’s infrastructure of oppression is no longer confined to its own borders. It is being actively deployed to support other regimes in building systems of control that reach into every aspect of life.

In Iran, this system is already being used to silence dissent, hide abuses, and maintain power at any cost.

It is a sad day for freedom
