NARRATIVE: China arms itself with a legal arsenal to surveil global supply chains

Introduction: Beijing rewrites the rules of the global industrial game

Two decrees, one unambiguous message

In the span of a few weeks across the spring and summer of 2026, China enacted and put into force a legislative arsenal that fundamentally alters the risk landscape for foreign companies operating in — or simply connected to — the Chinese economy. On March 31, 2026, the State Council published Decree 834 — the Regulations on Industrial and Supply Chain Security. On April 7, 2026, it published Decree 835 — the Regulations on Countering Foreign Extraterritorial Jurisdiction. Both took effect immediately. On June 24, 2026, the Ministry of Commerce released the implementing rules for Decree 834 — a 22-article document spelling out the scope, content, procedures, and remedies of supply chain security investigations.

These texts are not routine bureaucracy. They represent a deliberate — and offensive — response from Beijing to a decade of Western pressure: American export controls on semiconductors, European investigations into Chinese subsidies, attempts to "decouple" supply chains. What China is building is its own version of the long legal arm — the same instrument that the United States and the European Union have wielded for decades to project their law beyond their borders. The difference: Beijing is deploying it with the full weight of an $18 trillion economy.

Decree 834: monitoring industrial security — and investigating it

The scope of the new industrial security investigations

Decree 834 authorizes the Chinese Ministry of Commerce to open investigations into industrial security threats — a deliberately broad notion, not defined in any restrictive way in the text. These investigations can target foreign companies whose activities are deemed capable of threatening the resilience or security of Chinese industrial supply chains. The implementing rules published on June 24, 2026 clarify the procedures: investigation timelines, response rights, the nature of possible remedies. But international legal observers, notably the firm Linklaters, note that the definition of "industrial security threat" remains wide enough to allow for discretionary application.

The potential geographic reach is troubling for foreign businesses. A company that decides to reduce its dependence on Chinese suppliers — an entirely ordinary risk management decision — could theoretically be considered as creating a "supply chain security threat" by disrupting Chinese industrial networks. If that interpretation were adopted by Chinese authorities, it would transform normal commercial decisions into legal risks under Chinese law.

Decree 835: pushing back against extraterritorial jurisdiction

The first application: the European investigation into Nuctech

Decree 835 responds directly to a long-standing irritant: American and European laws with extraterritorial reach — particularly U.S. sanctions against companies that trade with sanctioned entities, and European investigations into foreign subsidies — that affect Chinese companies without going through Chinese law. Decree 835 gives the Chinese government tools to identify these "improper" extraterritorial applications of foreign law, publish blacklists, and take retaliatory measures.

That text was applied without delay. On May 15, 2026, the Chinese Ministry of Justice issued its first formal determination under Decree 835: the European Commission's investigation into subsidies granted to Nuctech — a state-linked Chinese security equipment company — constitutes an "improper extraterritorial application of foreign law." This formal determination sends an explicit signal: Beijing is ready to deploy its legal arsenal against legitimate European regulatory investigations. And this is only the beginning.

The law allowing prosecution of foreign entities

A retaliation lever against foreign companies and individuals

Alongside Decrees 834 and 835, China has also put in place a legislative framework allowing state prosecutors to pursue foreign entities that cause harm to Chinese national interests. This mechanism extends Chinese criminal and civil jurisdiction to actors who are not necessarily on Chinese soil — an extraterritorial logic analogous to the one Beijing denounces in its adversaries. International legal experts note that this provision could be applied against journalists, academics, consultants, or business executives who produce analyses or commercial decisions deemed harmful to Chinese interests.

The intended chilling effect is obvious. If an American risk analyst publishes a report recommending that clients reduce their exposure to Chinese semiconductor suppliers, could that analyst theoretically face prosecution under this framework? The legal answer is nuanced — enforcement options are limited if the person never sets foot in China or in a country with extradition agreements. But the chilling effect on research and analysis is real, and has been documented in other extraterritoriality contexts.

The context: a response to a decade of Western pressure

U.S. sanctions, European investigations, technological decoupling

To understand these texts, they must be placed in context. Since 2018 and the start of the Sino-American trade war under the Trump administration, followed by the Biden administration's advanced semiconductor export controls, China has faced constant and growing pressure from its main Western trading partners. The European Union has stepped up its investigations into Chinese subsidies, blocked mergers involving Chinese companies, and launched inquiries into Chinese electric vehicles and solar panels. The United States has expanded lists of Chinese entities subject to export restrictions.

In this context, Decrees 834 and 835 are not passive defensive measures — they are a legal counter-offensive. Beijing is saying implicitly: "If you use your laws to restrict our companies, we will use our laws to protect our supply chains and restrict yours." This is the logic of asymmetric reciprocity — China cannot quite replicate American financial sanctions, but it can create equivalent legal risks in the commercial and industrial domain.

The concrete risks for Western businesses

Who is exposed and how

The Western companies most exposed to these new texts are those with significant operations in China — manufacturing, research, distribution — while simultaneously maintaining activities in sectors subject to U.S. or European export controls. A semiconductor company that sells to Chinese customers while subject to U.S. export controls finds itself in a potential double risk zone: risk of U.S. sanctions if it sells too much, risk of Chinese investigation if it sells too little or decides to exit. This "double exposure" situation is new and has no established precedent.

Logistics and transportation companies are also affected. The interdependence of global supply chains means that almost any decision to reorganize logistics involves China — whether in component supply, final assembly, or distribution. The firm Linklaters notes in its analysis of Decrees 834 and 835 that both texts "elevate counter-measures to the level of China's highest legislative authority" and "introduce new enforcement powers" — giving them stronger institutional legitimacy than previous regulatory measures.

The WTO marginalized: new instruments of economic warfare

When multilateral rules no longer apply

One of the most troubling aspects of this evolution is the marginalization of the World Trade Organization (WTO) as an arbiter of trade disputes. The WTO was designed for a world where the principal commercial actors — the United States, the European Union, Japan — shared a fundamental interest in a rules-based trade order. That world no longer exists. Trump's United States imposed sweeping unilateral tariffs. China developed its own extraterritorial tools with Decrees 834 and 835. The EU uses its Foreign Subsidies Regulation as an industrial policy instrument. Everyone plays their own game — and companies pay the price of this fragmentation.

The WTO's dispute settlement mechanism — already weakened by the U.S. blockade of Appellate Body appointments since 2019 — is incapable of addressing these new instruments at the pace they are being deployed. This institutional vacuum benefits those with the most powerful legal arsenals. China, with Decrees 834 and 835, has just significantly reinforced its own. The question for the West: does it want to restore a multilateral framework, or continue playing the game of unilateral reciprocity? China is prepared to play that game for a very long time. The West has voters to convince at every election cycle.

The Nuctech precedent: a test of European resolve

The first application of Decree 835 against the European Commission's investigation into Nuctech is a textbook case. Nuctech supplies security equipment to European airports and ports — critical infrastructure that several governments have flagged as concerning given the company's documented ties to the Chinese state. The European investigation was legitimate under the Foreign Subsidies Regulation. The Chinese determination of May 15, 2026 is an attempt to block it by labeling it an improper extraterritorial application of foreign law. The EU must hold its ground — conceding would signal that its regulatory tools can be neutralized by Chinese legal pressure.

For European companies operating in China, this precedent illustrates the cross-cutting risk: exposed simultaneously to the regulations of their own government and to Chinese counter-measures. Linklaters notes that Decrees 834 and 835 "have already been applied" — they are active tools, not theoretical threats. China is testing their reach in real time, with direct consequences for Western companies and regulators. Vigilance is required, now.

Conclusion: A signal about the nature of the new global trade disorder

What these decrees reveal about Beijing's strategy

Beyond the legal details, these texts send a clear strategic signal: China will not remain passive in the face of Western attempts to restructure global supply chains to reduce dependence on it. It has economic, legal, and political tools to complicate, slow, and penalize those restructurings. The publication of implementing rules on June 24, 2026 — precisely as discussions about technological decoupling accelerate in the West — is no coincidence of timing.

What the international commercial world must understand is that the global economy is now a legally contested space to a degree unseen since the Second World War. The rules of multilateral trade — those of the World Trade Organization — are being systematically circumvented by all the major players. It is not only China that is challenging the liberal trade order: Trump's United States is doing so with its unilateral tariffs. The difference is that China now has tools to strike back with precision — not just counter-tariffs, but targeted investigations, prosecutions, and blacklists.

The reciprocity challenge: how the West must respond

Two options facing China's legal arsenal

Faced with this Chinese legal arsenal, Western democracies have two options: regulatory escalation — replicating with their own even more constraining measures — or negotiating a framework of mutually acceptable rules for supply chain investigations and foreign investment. The first option carries the risk of a legal spiral that fragments global trade further. The second requires political will that seems, for now, to be absent in a context of intense geopolitical rivalry.

What is certain is that the era of naive globalization — where companies could operate in authoritarian economies without accounting for political and legal risks — is over. Decrees 834 and 835 are the most recent proof. What Beijing built in 2026 is not a legal wall against the outside world. It is a platform for intervening in the functioning of the global economy. And that platform is now active.

My position and my sources

This article addresses a commercial and legal subject. My position is to alert readers to the strategic implications of these decrees for Western democracies and the companies that operate within them. The legal facts — dates, decree numbers, content — come from identified sources: Xinhua, China Daily, the firm Linklaters. I do not invent any figures or any legal implications without supporting them with a source.

What I do not know

I do not yet know the full extent of how these texts will be applied — they are recent and few precedents exist. I do not know whether Chinese authorities will apply the provisions broadly or narrowly. The analyses I cite (Linklaters) are preliminary analyses, not court decisions.
