## Introduction: when "maritime law enforcement" becomes a geopolitical weapon

### An operation labeled "maritime law enforcement"

In early **June 2026**, the **China Coast Guard (CCG)** conducted what it officially described as a "special maritime law enforcement and hydrography operation" in waters **east of Taiwan**. On the surface: a routine operation within the legal framework of China's claimed waters. In reality, according to analysts from the **Washington Times**, the **ISW**, and other institutions: the methodical rehearsal of a maritime blockade of the island.

A flotilla of **five CCG vessels** issued radio challenges to **three foreign merchant ships** in waters **35 nautical miles southeast of Taiwan** — a location in the **open Western Pacific**, not in the **Taiwan Strait**. This geographic detail is crucial: **China** is no longer confining itself to the strait. It is extending its claims to a second strategic zone east of the island. A full encirclement in the making.

### Terminology as a tool of cognitive warfare

**Chinese Foreign Ministry spokesperson Guo Jiakun** justified the patrols as "legitimate actions" within China's **Exclusive Economic Zone** and on its **continental shelf** "in the waters east of China's Taiwan island." This formulation — "China's Taiwan island" — is not incidental: it denies the very existence of a separate political entity called **Taiwan** and frames any international reaction as interference in China's internal affairs.

It is a well-known strategy: reframe an aggressive action as an exercise of legitimate sovereignty, progressively impose a unilateral legal framework, and compel other states either to comply or be accused of "violating" Chinese sovereignty. The **South China Sea** underwent this gradual transformation over many years. The waters east of **Taiwan** are now in the crosshairs.

*When China calls its militarized patrols "maritime law enforcement," it is playing on our tendency to take words at face value. We must look at them directly: these are encirclement rehearsals. The legal dressing changes nothing.*

## The blockade plan: anatomy of a strangulation strategy

### How you blockade an island of 23 million people

A blockade of **Taiwan** would not resemble a traditional high-seas blockade. The strategy that **Beijing** appears to be rehearsing is more subtle: control all navigation entering and leaving the island by requiring prior authorization for each ship, reserving the right to inspect, board, or seize vessels. This is not open warfare — it is a gradual strangulation, slow enough to make any military response politically difficult to justify, yet effective enough to suffocate an island economy that imports **98%** of its oil and a large proportion of its raw materials.

On **June 25, 2026**, Taiwanese officials simulated exactly this scenario in a tabletop exercise: **China** demands that commercial ships bound for **Taiwan** obtain its prior approval. In the scenario, **Beijing** "inspects, boards, or seizes" ships. The Taiwanese response mobilized coast guard forces, naval forces, and ground combat units — meaning that even an economic escalation of this kind would trigger a military response.

### The logic of escalation: from grey to war

One reason blockade is the strategy some analysts favor for **Beijing** is that it offers a pressure gradient that does not immediately cross the threshold of a conventional act of war. **China** could begin with "routine checks" on a few ships, escalate to systematic inspections, then to cargo diversions, and finally to a complete closure of maritime routes — each step presented as a legal measure under its claimed sovereignty.

This graduated escalation approach is precisely what operations in the **South China Sea** have tested for years against the **Philippines** and **Vietnam**. What we are now observing east of **Taiwan** looks like the same recipe, applied to a strategically far more important target.

*Gradual escalation is the hallmark of China's coercive strategy. You wait for the other side to adapt, then you advance a step. If the West draws no lesson from the South China Sea, it will be surprised — once again — when the same thing happens in the Pacific.*

## Operational evidence: what the patrols reveal

### Location of the incidents: the Pacific, not the strait

The fact that Chinese patrols took place in the **Western Pacific**, **east** of **Taiwan**, and not in the **Taiwan Strait**, is significant on several levels. First, these waters are internationally recognized as international waters — China's claim to exercise **EEZ** jurisdiction there is contested by virtually all coastal states in the region and by **international maritime law**. Second, controlling these waters would mean cutting maritime lines of communication between **Japan** and the **United States** — a strategic implication that extends well beyond the Taiwan question alone.

The **Hague tribunal** had already ruled in **2016** that China's claims over vast swaths of the **South China Sea** had no legal basis. **Beijing** rejected that ruling. The same logic now applies to eastern Taiwanese waters: **China** invokes a sovereignty that international law does not recognize, and is counting on democracies' hesitation to contest it physically.

### The Fujian's passage: the carrier as signal

On **June 24, 2026**, simultaneously with the opening days of Taiwanese military exercises, China's newest and most technologically advanced carrier — the **Fujian** — transited the **Taiwan Strait**. Surveillance images published by **Taiwan** show the vessel in its waters. This deployment coincides with coast guard maneuvers east of the island — as if **China** were simultaneously rehearsing encirclement from two opposing axes.

The **PLA Navy (PLAN)** is also improving its at-sea refueling capacity, enabling it to sustain carrier strike groups beyond the **first island chain** for extended periods. The carrier **Liaoning** had just returned from a **40-day** deployment in the **Western Pacific** and **South China Sea**, according to the **ISW**. China's maritime projection capability is no longer theoretical — it is operational.

*The Fujian in the strait while the CCG patrols to the east: this is a two-branch encirclement rehearsal. Whether it is conscious and coordinated or simply opportunistic, the result is the same — Taipei must now defend two maritime fronts simultaneously.*

## The international reaction: statements and their limits

### The United Kingdom, France, and Germany speak out

On **June 24, 2026**, the de facto representations of **Britain**, **France**, and **Germany** in **Taipei** issued a rare joint statement, expressing concern about "new Chinese activities" in eastern Taiwanese waters. The statement said these actions "threaten regional stability and freedom of navigation and safety of international shipping," and reiterated these countries' opposition "to any unilateral change to the status quo, in particular by threat or use of force or coercion."

The U.S. State Department separately described Chinese actions as "deeply destabilizing." These positions are important signals — but they do not constitute security guarantees. None of these statements mention concrete consequences, sanctions, naval deployments, or any commitment to defend **Taiwan** in the event of aggression. It is the language of diplomatic concern, not of a security guarantee. This distinction is fundamental.

### The limits of a verbal response

A recent wargame, whose results were published in mid-**June 2026** by the **Washington Times**, concluded that **Europe** and **South Korea** would not be effective respondents in a **Taiwan** crisis. The **EU**, according to the report, "prioritizes internal consensus-building, often at the expense of swift external action in crisis scenarios." This harsh but realistic conclusion serves as a reminder that declaratory power and action power are two very different things.

**China** knows this. And **Beijing** is betting precisely on that difference: that Western democracies will condemn verbally but hesitate militarily. This bet is not irrational — it has been confirmed on multiple occasions by recent history. Which makes the current patrols all the more alarming.

*Condemning China verbally without concrete consequences sends it a signal of impunity. I don't claim to have the solution — imposing consequences on a nuclear power that controls a large share of your supply chain is an extraordinarily difficult decision. But continuing not to do so also has a cost.*

## The instrumentalization of the Japan-Philippines pretext

### The maritime dispute as cover

**Beijing** officially justified its east-Taiwan patrols as a response to maritime boundary negotiations between **Japan** and the **Philippines**. In June, these two countries had announced discussions to delimit their exclusive economic zones in waters that **China** also claims. **Beijing** therefore presented its patrols as a defense of its sovereign rights — not as pressure on **Taiwan**.

This pretext is convenient but transparent. The areas in question are geographically distinct from those at issue in the Japan-Philippines dispute, and the interception of commercial ships **35 nautical miles** from **Taiwan** cannot reasonably be connected to a Japan-Philippines border dispute. What **China** is testing is its ability to exercise de facto jurisdiction in the **Western Pacific**, using successive legal pretexts to normalize its presence.

### The involvement of Japan and the Philippines

The reaction from **Japan** and the **Philippines** to these patrols was significant — both countries protested Chinese actions, which directly affect their own claimed waters. **Japan**, which maintains its own territorial dispute with **China** over the **Senkaku/Diaoyu** islands, views east-Taiwan operations as a direct extension of pressure on its own maritime interests. An escalation in the **Western Pacific** would not concern only **Taiwan** — it would affect the entire region.

This is precisely why the tripartite declaration from **Britain, France, and Germany** carries more weight than it might initially appear. It signals that **Europe** is beginning to perceive the connection between its own freedom of commercial navigation — on which its economy depends — and what is happening in the **Western Pacific**.

*Europeans import Taiwanese semiconductors, depend on Pacific maritime routes, and have massive commercial interests in Asia. What is happening around Taiwan is not an Asian problem — it is a global problem. It is time European capitals drew the practical consequences.*

## Blockade exercises as an emerging doctrine

### From exercise to doctrine: the gradual normalization

The **4 "combat readiness" patrols** conducted by the **PLA** in **May 2026** alone, the **CCG** maneuvers east of **Taiwan**, the **Fujian**'s transit through the strait, and the **PLAN**'s extended refueling exercises beyond the first island chain together form a coherent pattern. This is not reactivity — it is an emerging doctrine of preparation for the encirclement of **Taiwan**.

**The Diplomat** had characterized as early as **May 2026** **Beijing**'s strategy toward **Taiwan** not as a "D-Day conquest" but as a gradual strangulation through hybrid means — recurring patrols, frequent exercises, economic pressure, cognitive warfare. The objective may not be a spectacular invasion, but a progressive degradation of resistance capacity and international willingness to respond.

### The patrol cadence as an attrition tool

Every time **Taiwan** deploys ships, aircraft, or coastal missiles to respond to a Chinese patrol, it incurs costs in fuel, maintenance, crew time, and psychological wear. Multiplying these incidents — without ever crossing the threshold of an act of war — allows **China** to gradually exhaust Taiwanese defenses and morale. It is attrition warfare applied to peacetime.

Taiwan's **Ministry of Defense** documented in **May 2026** an **ADIZ** penetration rate of **79%** for **PLA** sorties — the highest of the year. Each incursion, each interception, each cycle of alert and response affects the operational availability of Taiwanese forces. This is **Beijing**'s strategic calculation: degrade before acting, if action ever proves necessary.

*The real question is not "will China attack?" — it is "when will hybrid pressure alone have sufficed to force Taipei into concessions without a single shot fired?" This form of silent victory may be the one Beijing actually prefers.*

## The China Coast Guard as the arm of a hybrid strategy

### A progressive militarization of the coast guard

The **China Coast Guard (CCG)** underwent a major institutional transformation after **2021**, when **China** adopted a law permitting it to use weapons against foreign ships in waters it claims. Since then, the **CCG** has become a leading instrument of Chinese maritime pressure — notably in the **South China Sea** against the **Philippines**, and now increasingly around **Taiwan**. The advantage of the **CCG** as a coercion instrument lies precisely in its statutory ambiguity: it is not formally the military navy, which allows **Beijing** to deny a military dimension to its actions.

The **CCG** vessels deployed east of **Taiwan** in **June 2026** were among the largest in the fleet — equipped with water cannons and light armament, capable of conducting "checks" on commercial ships. These capabilities go well beyond simple surveillance: they allow for the interception, inspection, and potential diversion of merchant vessels — exactly the kind of actions that a progressive blockade would require.

### The "grey zone" doctrine and its application to Taiwan

The "grey zone" doctrine — coercive actions below the threshold of conventional armed conflict — is at the heart of China's strategy around **Taiwan**. **CCG** patrols, frequent **PLA** flights into the **ADIZ**, repeated exercises, research vessel activity in disputed waters — all these actions are designed to gradually alter the status quo without triggering a decisive allied military response.

**The Diplomat** analyzed this strategy as early as **May 2026** as a "conquest without D-Day" approach — a silent victory through an accumulation of pressures, without a single main shot fired. Within this framework, the east-Taiwan patrols of **June 2026** are one more step in a long-term process, not an isolated provocation.

*The "grey zone" strategy is insidious precisely because it never crosses the threshold that would trigger a clear armed response. It advances like sand in an hourglass — imperceptibly, inexorably. And by the time the change is noticed, it is often too late to reverse easily.*

## Possible countermeasures: what democracies can do

### Freedom of navigation as a practical response

The most direct response to Chinese patrols is the physical assertion of international freedom of navigation. The **United States** regularly conducts **Freedom of Navigation Operations (FONOPs)** in waters that **China** excessively claims — notably in the **South China Sea**. **FONOPs** in the waters east of **Taiwan**, in direct response to Chinese patrols, would send a clear signal that the international community does not recognize **Beijing**'s maritime claims in that zone.

European **FONOPs** in these waters would have an even greater symbolic impact — they would signal that European engagement in the **Indo-Pacific** goes beyond statements. The **Royal Navy** and the **French Navy** have the capability to conduct such operations — and their presence in the region is justified by European commercial and strategic interests in Pacific freedom of navigation.

### Sanctions as a response to maritime coercion

Another possible response — and one largely underused so far — consists of preparing pre-loaded sanctions activatable in the event of Chinese escalation around **Taiwan**. Identifying in advance which economic sectors, which Chinese entities, and which individuals could be targeted in the event of coercive actions by **Beijing** — and making this publicly known — constitutes a form of economic deterrence. The **Washington Times** wargame of **June 2026** recommended precisely that the **EU** "pre-prepare sanctions packages" for this type of scenario.

This approach has the advantage of placing real pressure on Chinese decisions without requiring military action. It is politically easier to adopt in advance than in the middle of a crisis. And it gives concrete substance to diplomatic declarations — transforming words into credible threats.

*FONOPs and pre-loaded sanctions packages are not grand heroic solutions. But they are practical, concrete, immediately usable tools. In crisis management, practical tools are often worth more than grand declarations.*

## Conclusion: repetition is a strategy

### What these patrols really mean

Chinese patrols in eastern Taiwanese waters and around the **strait** are not isolated events or improvised reactions. They are part of a deliberate and documented strategy: test international responses, normalize a military presence, rehearse encirclement maneuvers, and progressively erode the threshold at which these actions would be considered provocations. It is a hybrid warfare playbook applied to the most valuable geopolitical stake of our time.

### The West's obligation of clarity

Faced with this strategy, the **West**'s response must be clear and concrete. Joint British-French-German declarations are useful — but they do not deter a nuclear power with a long-term strategy and a high tolerance for diplomatic pressure. What deters is the certainty that aggression will have severe economic, military, and strategic consequences. That certainty remains to be built.

*China's strategy around **Taiwan** is patient, methodical, and designed to play out over decades. The Western response must be equally patient — and far more determined than it has been so far. The patrols of **June 2026** are a warning. We should not wait for the next ones before acting.*

## Columnist's transparency note

### Editorial stance

I am not a journalist but a **columnist and analyst**. My expertise lies in observing and analysing the geopolitical, economic and strategic dynamics that shape our world. My work is to take political strategies apart, to understand global economic movements, to put the decisions of international actors in context and to offer analytical perspectives on the changes that are redefining our societies.

I do not claim the cold objectivity of traditional journalism, which stops at reporting facts. **I claim analytical clarity**, rigorous interpretation and a deep understanding of the complex issues that concern us all. My role is to give meaning to the facts, to place them in their historical and strategic context, and to offer a critical reading of events.

### Method and sources

This text keeps the basic distinction between **verified facts and interpretive analysis**. The rule never changes: a factual claim is published only when a verifiable source supports it, and the sources this article actually used are listed under **Sources**, never here.

**Primary source families** used by the publication, when the story has them: official statements from governments and international institutions, public statements by political leaders, reports from intergovernmental organisations, dispatches from recognised international news agencies.

**Secondary source families**: specialised publications, internationally recognised news media, analyses from established research institutions, reports from industry organisations.

When an article cites statistical, economic or geopolitical data, it comes from the institutions that produce it (intergovernmental organisations, central banks, national statistics offices), and the exact institution is named under **Sources**.

### Nature of the analysis

The analyses, interpretations and perspectives in the analytical sections of this article are a **critical, contextual synthesis** based on the information available, the trends observed and the expert comments cited in the sources consulted.

My role is to interpret these facts, to set them in the context of today's geopolitical and economic dynamics, and to give them a coherent meaning within the larger story of the changes shaping our time. These analyses reflect expertise built through continuous observation of international affairs and an understanding of the strategic mechanisms that drive global actors.

This article describes a documented state of affairs on its publication date, not a prediction: later developments may shift its outlook. No update is promised in advance; when an article is corrected or completed, the change is dated in the text.
