DECODING: The Chinese Coast Guard Legalizes Boarding: Taiwan in the Legal Vise

DECODING: The Chinese Coast Guard Legalizes Boarding: Taiwan in the Legal Vise

Introduction: Law as a weapon — Beijing turns its patrols into jurisprudence

June 2026: when coast guard vessels rewrite maritime law

Since June 1, 2026, a flotilla from the Chinese Coast Guard (CCG) has been patrolling almost continuously in the waters east of Taiwan's main island. What could have been yet another military show of force is in reality something far more subtle and far more dangerous: a legal construction operation. By conducting "maritime order maintenance" patrols, querying commercial merchant vessels about their origin and destination, and proclaiming jurisdiction over those waters, Beijing is not merely asserting its presence — it is creating precedents, normalizing behaviors, and building the foundations of a legitimacy it intends to invoke during a future blockade or military operation.

The Institute for the Study of War (ISW) documented this strategy in its June 26, 2026 assessment with unambiguous clarity: "China likely aims to erode Taiwan's sovereignty and establish itself as the sole legitimate guardian of China's maritime borders, including those around Taiwan." That sentence captures the entire stakes: this is a war of legal legitimacy, waged with white vessels rather than grey ones, but with geostrategic objectives every bit as serious as any military operation.

The Japan-Philippines pretext and the disproportionate response

The official pretext for China's patrols east of Taiwan is the decision by Japan and the Philippines to open formal discussions on delimiting their maritime borders in that zone — a discussion both countries have every right to conduct under international law. Beijing responded to that announcement on June 6, 2026 by launching a "special maritime traffic order-maintenance operation" east of Taiwan — a five-day operation that ended on June 10 but whose regular patrols continued through late June.

The reaction is manifestly disproportionate to the stated pretext. Tokyo and Manila discussing their mutual maritime borders does not justify a large-scale operation involving vessels from the CCG, the Ministry of Transport, and the Ministry of Natural Resources. The real target is not Japan-Philippines — it is Taiwan, whose waters lie precisely within the zone Beijing claims. This operation is the first in a series within a framework of gradual control that the ISW describes as the "nearshore governance" expansion model.

The 2021 Coast Guard Law: the legal architecture of power

When China legislates for the world's oceans

To understand the nature of the threat, we must go back to the Chinese Coast Guard Law adopted by the National People's Congress on January 22, 2021. This law — whose provisions were supplemented by implementing regulations that entered into force on June 15, 2024 — constitutes the legal backbone of the CCG's current operations. Its Article 22 authorizes the Coast Guard to "take all necessary measures, including the use of weapons" to end any violation of China's sovereignty or maritime rights by foreign organizations or individuals.

The 2024 regulations go even further: they authorize the Coast Guard to board, inspect, and detain foreign vessels and their crews in waters China claims, for immigration violations. Those crews may be held for up to 60 days. This provision creates a legal basis — under Chinese law, not international law — for boarding operations in waters that Taiwan, Japan, the Philippines, and the international community do not recognize as falling under Chinese sovereignty.

The vague definition of "waters under Chinese jurisdiction"

The central point of the legal controversy is the very definition of "waters under Chinese jurisdiction" in the 2021 law. The law uses this phrase without defining it precisely — deliberately so. China de facto claims maritime rights over all waters surrounding Taiwan on the basis of its claim to sovereignty over the island itself. If Taiwan is Chinese, then Taiwanese waters are Chinese. The reasoning is circular and unrecognized under international law — but it is legally consistent within the framework of the One China policy Beijing imposes.

In practice, this ambiguity allows the CCG to operate in undefined waters with an internal legal basis while maintaining external ambiguity. Foreign vessels that receive CCG orders face an impossible choice: complying implicitly acknowledges Chinese jurisdiction; refusing risks a diplomatic or physical incident. The spokesperson for Taiwan's National Security Council, Wu Chao-hsie, described Chinese actions as a "serious escalation of regional tensions."

The June 2026 operation: 198 vessels "inspected," 3 "irregularities corrected"

The rhetoric of ordinary legitimacy

China presented its special operation in June 2026 east of Taiwan with the bureaucratic banality of routine procedure. The official state news agency Xinhua reported that the operation had "inspected 198 vessels" and "corrected 3 violations of regulations and laws." These figures are presented as the normal results of legitimate maritime policing activity — which they would be in uncontested Chinese waters. In the waters east of Taiwan — international waters, Taiwan's exclusive economic zone — they represent something radically different.

The three vessels queried were a Singaporean ship, a Liberian ship, and a Beninese ship — flags of convenience used by global maritime trade. Vessels whose owners and crews have no connection whatsoever to the China-Taiwan dispute, but who found themselves caught in the legal ambiguity Beijing has created. Taiwanese authorities advised these vessels to ignore Chinese communications — placing captains and owners in an awkward position between two contradictory legal systems.

China's "harassment" vs. Beijing's "legitimacy"

The Taiwan Coast Guard Administration (CGA) denounced the CCG's conduct as "harassment" of commercial vessels — demanding information about their origin and destination, claiming jurisdiction in Taiwanese or international waters. Taiwan broadcast its own radio messages to the affected vessels: "This is Taiwan's Exclusive Economic Zone. China has no jurisdiction here. Please disregard communications from Chinese official vessels."

China, through its Ministry of Foreign Affairs, the Taiwan Affairs Office, and the Ministry of Defense spokesperson, responded on a consistent register: the patrols are "legitimate and necessary" and constitute "a justified action to protect national sovereignty and maritime rights." These statements are carefully worded to never admit doubt, constructing a legitimacy narrative repeated until it becomes, in circles that do not examine the legal foundations, an apparent truth.

Western alarm: the United States, United Kingdom, France, Germany

The coordinated response of four powers

On June 24, 2026, the United States, the United Kingdom, France, and Germany issued a joint statement expressing concern about Chinese patrols east of Taiwan. This quadrilateral coordination is significant — it demonstrates that concerns about Chinese maritime activities are no longer limited to geographically affected countries but are part of the strategic concerns of the major Western democracies.

According to Defense News, which covered the statement, the four countries indicated that Chinese actions "threaten regional stability and freedom of navigation." This language is precisely what treaties and international maritime law use to define unacceptable conduct — not coincidentally, but as a deliberate reference to a legal framework that China claims to respect but systematically violates whenever it conflicts with its territorial ambitions.

Taiwan's tabletop blockade exercise

Three days later, on June 25, 2026, Taiwanese officials conducted a tabletop exercise to plan a response to a potential Chinese maritime blockade. The scenario: the Chinese CCG declares that all vessels entering and leaving Taiwanese ports must obtain Beijing's approval. The simulated measures escalate from inspection to boarding, then to vessel seizure — exactly the powers that the 2021 CCG law formally confers.

Taiwanese President Lai Ching-te opened the resilience committee meeting by denouncing China's "expansionist activities disguised as law enforcement." Taiwan's planned response is comprehensive: robust Coast Guard deployment on the front line, immediate combat exercises for the armed forces, and an international public-relations campaign to demonstrate that Chinese actions "violate illegal boarding and inspections under international law and threaten freedom of navigation."

The "Kinmen model" and its extension: a strategy of progressive encirclement

From the strait to eastern waters: geographic expansion

To understand the strategic significance of the June 2026 operations, they must be placed in the context of China's strategy of progressive encirclement of Taiwan. The "Kinmen model" — a term used by the CCTV-affiliated social-media account Yuyuan Tantian — refers to the repeated CCG deployments around the Taiwanese islands of Kinmen (Jinmen), located in close proximity to China's coastline. These operations, normalized since 2024, have progressively extended the effective CCG presence into waters Taiwan considers its own.

The extension to waters east of Taiwan represents a qualitative leap: from the South China Sea and the Taiwan Strait, the Chinese presence now extends into the Western Pacific — the waters that separate Taiwan from its fuel and Pacific supply routes. This eastward extension is strategically critical: these are the waters through which ships bringing relief to Taiwan would transit in a conflict, where allied submarines would patrol, and where American logistical support lines would run. Controlling these waters, even under the guise of maritime policing, complicates any external support operation for Taiwan.

"Nearshore governance" as a doctrine of progressive expansion

The concept of "nearshore governance" introduced by Yuyuan Tantian in June 2026 is a significant doctrinal innovation. It suggests that China no longer views the waters around Taiwan as contested spaces to be resolved militarily, but as an administrative zone to be governed progressively through policing means. Within this framework, every CCG patrol is an act of governance, every merchant vessel query is routine police work, and every bathymetric survey is an act of territorial administration.

This conceptual framework is extraordinarily useful for Beijing because it shifts the dispute from the military to the administrative domain. It is harder for Western democracies to justify a military response to a "maritime policing operation" than to a naval attack. And if normalization succeeds — if commercial vessels begin complying with CCG orders, if third-party states no longer react to each incident — then Beijing will have effectively established de facto jurisdiction without firing a single shot.

The ISW analysis: strategic implications for the PLAN

Freeing the navy for open-ocean missions

The ISW identified in its June 26, 2026 assessment a strategic implication that few commentators have highlighted: by extending the CCG's operational presence east of Taiwan, China can free assets of the People's Liberation Army Navy (PLAN) for missions on the open ocean, beyond the "first island chain." In Chinese blockade exercises targeting Taiwan, the CCG is responsible for covering the Taiwan Strait while the PLAN covers the eastern approaches. Extending the CCG to eastern waters would allow the PLAN to deploy even more assets farther into the Pacific.

This implication is profound. It means that CCG operations east of Taiwan are not only a legal construction exercise — they are also a tactical reorganization in preparation for larger-scale operations. By preparing the CCG to manage Taiwan's eastern waters, China is freeing its navy for missions that could contest American naval supremacy in the Western Pacific — missions that could complicate or delay any American intervention in a Taiwan crisis.

Submarine cable patrols: a critical threat

Another aspect documented by the ISW is particularly alarming: in its activities east of Taiwan, the CCG has patrolled areas where submarine cables are located. These cables carry approximately 95 percent of international communications. A military operation that cut these cables — something the ISW notes China has rehearsed in exercises — would plunge Taiwan into near-total communications isolation.

The CCG's presence in these areas is already, in peacetime, a way of accumulating bathymetric and logistical knowledge about the zones — who operates them, how they are monitored, what their precise coordinates are. This operational knowledge is discreet but real preparation for future escalation scenarios. In a crisis, the party that knows the precise location of the adversary's submarine cables holds a significant advantage.

Taiwan: between remarkable resilience and structural vulnerabilities

Combat exercises and civil preparedness

Taiwan's response to growing CCG pressure is not capitulation — it is reinforcement. In June 2026, Taiwan conducted five days of "combat readiness" exercises from June 21 to 25. These exercises tested coordination among the armed forces, Coast Guard, and civilian agencies. Taiwan also conducted its tabletop exercise on June 25 specifically centered on a Chinese maritime blockade scenario.

The CGA plans to expand the use of drones in its maritime operations, following a competition involving more than 50 certified drone pilots who demonstrated precision and response capability. These drones will be used to monitor CCG intrusions into Taiwanese waters — a technological adaptation directly inspired by the Ukrainian drone war. The ability to monitor, document, and respond to CCG incursions is steadily improving.

The vulnerabilities that remain real

Despite this resilience, Taiwan's structural vulnerabilities are real. The island depends on imports for 97 percent of its oil. Its ports are concentrated on the western coast, closest to China's shores and the strait. Its navy and coast guard are incomparably smaller than Chinese forces. And politically, Taiwan's internal cohesion — despite its vibrant democracy — is subject to constant pressure from Chinese propaganda and influence operations, which recent AEI studies document as intensifying.

The question is therefore not whether Taiwan can resist a direct military attack on its own — that is probably not sustainable over time. The question is whether the West — and the United States in particular — maintains a presence and deterrence credibility sufficient to prevent Beijing from ever running that calculation. And that is precisely where CCG patrols play a direct role: by testing the boundaries of Western response, measuring Taipei's resistance, and accumulating a de facto presence that precedes and facilitates potential future operations.

The international dimension: law of the sea vs. Chinese law

UNCLOS vs. the CCG Law: two visions of the maritime world

The legal conflict between China and Taiwan (and its allies) over the waters east of the island is fundamentally a clash between two visions of international maritime law. The United Nations Convention on the Law of the Sea (UNCLOS), to which China is a signatory, establishes that waters more than 12 nautical miles from a state's coasts are international waters open to free navigation. The Chinese CCG law, by contrast, claims to extend Chinese jurisdiction over waters that fall within the exclusive economic zone or the high seas under UNCLOS.

This legal tension is not new — China was defeated in 2016 by the Hague Arbitral Tribunal, which ruled its South China Sea claims incompatible with UNCLOS. Beijing simply refused to accept the verdict. This non-recognition of international law when it rules against Beijing is exactly the same logic Russia applies in Ukraine — two authoritarian regimes maintaining the fiction of respecting international law while systematically violating it whenever it conflicts with their territorial ambitions.

Freedom of navigation: a global issue

The waters east of Taiwan are not merely a bilateral matter between Taipei and Beijing. They are among the most heavily trafficked navigation routes in the world — commercial routes carrying billions of dollars in goods between Asia and the Pacific every year. The vessels from Singapore, Liberia, and Benin queried by the CCG in June 2026 had no connection to the China-Taiwan dispute — they were sailing on international commercial routes that China now claims to police.

That is why the joint statement by four Western democracies — the United States, the United Kingdom, France, Germany — on June 24, 2026 is so important. It signals that freedom of navigation is not merely a Taiwanese interest — it is a global interest affecting the trade of every country that uses these sea lanes. By declaring that Chinese actions "threaten regional stability and freedom of navigation," these four powers are defending an international maritime order that China is dismantling brick by brick.

Implications for a potential war: blockade before invasion

The logic of progressive economic blockade

Taiwan's tabletop exercise on June 25, 2026 modeled a stepwise escalation scenario: first information demands to vessels, then inspections, then boardings, then seizures. This progressive escalation is not fictional — it corresponds exactly to the sequence that Chinese military doctrine envisions for a coercive operation against Taiwan.

A successful economic blockade does not need to be total to be effective. If the CCG manages to convince international maritime insurers that the waters east of Taiwan are dangerous, insurance premiums rise. If they rise enough, shipowners reroute — and Taiwan finds itself progressively isolated economically without a single shot having been fired. This is the modern version of the medieval siege: not walls, but maritime insurance premiums and commercial hesitation.

The American military response: between commitment and strategic ambiguity

The United States officially maintains a policy of "strategic ambiguity" on whether it would intervene militarily if China attacked Taiwan. Under the Trump administration, this ambiguity has increased — statements in every direction, attention divided between Ukraine, Iran, and the Indo-Pacific, and contradictory signals about American strategic priorities in the region. China observes these hesitations and draws its own conclusions about the credibility of American deterrence.

In this context, the continued regular patrols of the U.S. Seventh Fleet through the Taiwan Strait and east of the island are a demonstration of commitment that matters. But they must be accompanied by clear and consistent political declarations. Strategic ambiguity, which may have had its logic during the Cold War, has become in the current context a source of miscalculation risk — Beijing could misread the absence of clarity as a signal of indifference rather than strategic flexibility.

The Ukrainian comparison: lessons not learned

Similarities with Russia's pre-2022 strategy

It is impossible to analyze China's strategy toward Taiwan without thinking about Russia's strategy toward Ukraine before February 24, 2022. Moscow too had accumulated gradual provocations: annexation of Crimea in 2014, support for Donbas separatists, massive military exercises at Ukraine's borders, influence and disinformation campaigns. Each of these provocations was met with insufficiently firm signals of determination — and Putin concluded that the West would not respond to a large-scale invasion either.

China has observed the Western response to the Ukrainian invasion very carefully — how the West actually responded far more strongly than anticipated, how sanctions were heavier, how weapons flowed to Kyiv. These observations constitute both a warning and a source of adaptation for Beijing. The CCG strategy east of Taiwan is designed precisely to avoid the kind of explicit red-line crossing that triggered the Western response in Ukraine — and to advance toward the same objectives in a more gradual and ambiguous manner.

The lesson the West must retain

The Ukrainian lesson for Taiwan is twofold. First, Western support for an attacked democracy can be stronger and more durable than an autocrat calculates in advance — that is a signal of hope. Second, waiting for aggression to become open and total before responding is a strategy that maximizes destruction and suffering before the response arrives — that is a warning signal. For Taiwan, the ideal would be to deter Beijing before missiles are launched, not to build a support coalition after an open conflict begins.

That is why naming and resisting the CCG's current strategy matters more than it may appear. Every normalized patrol without a clear response is one more step toward habituating China's presence in these waters. Every boarding accepted without protest is a precedent reinforcing Beijing's jurisdictional claim. Resistance must be early, consistent, and multilateral — exactly what the joint declaration by the four democracies on June 24, 2026 attempted to initiate.

Taiwan's exercises and civil preparedness: a democracy defending itself

Taipei's institutional response

Facing mounting pressure, Taiwan is not passive. The government of Lai Ching-te has multiplied signals of determination: high-intensity military exercises, development of coastal drone capabilities, Coast Guard reinforcement, civil preparedness for blockade scenarios. These measures are both practical — genuinely improving Taiwanese resilience — and political, signaling to Beijing that Taiwan will not be progressively intimidated.

Taiwan's democracy has demonstrated impressive political maturity under Chinese pressure. Successive governments — despite electoral alternations and internal political divisions — have maintained a remarkable level of strategic consistency. The Taiwanese population, according to regular polls, overwhelmingly supports maintaining the status quo of de facto separate governance. This social cohesion is itself a deterrent factor: invading a country whose population is unified in its resistance is an incomparably more costly undertaking than invading a fragmented one.

The critical role of international cooperation

Taiwan's resistance to CCG pressure cannot be entirely autonomous. It depends on maintaining American arms sales — which the Trump administration has not abandoned, despite ambiguous signals. It depends on cooperation with Japan and Australia — the regional powers most directly interested in strait stability. It depends on the resistance of international companies and shipowners to normalizing CCG orders.

This coalition of resistance must be nurtured, strengthened, and made more visible. Every American, Australian, or Japanese naval patrol in the waters east of Taiwan is a signal of commitment. Every joint statement by Western democracies condemning CCG conduct adds a layer of pressure on Beijing. And every government that continues to trade normally with Taiwan, maintain quasi-diplomatic relations, and supply defensive equipment contributes to sustaining the viability of a democracy of 23 million people facing Asia's greatest military power.

The technological dimension: drones and countermeasures in the strait

Taiwan develops its own coastal drone capabilities

The Taiwan Coast Guard Administration (CGA) announced in June 2026 its intention to integrate surveillance drones into its maritime operations. This decision followed an internal competition involving more than 50 certified drone pilots who demonstrated precision and responsiveness under near-real conditions. These drones are not attack systems — they are tools for surveillance, documentation, and early warning against intrusions by the Chinese CCG.

The Ukrainian inspiration is explicit in this approach: the drone war in Ukraine has demonstrated that a smaller nation can use drone technology to monitor, document, and respond to provocations by a larger adversary. By adapting these lessons to the maritime context, Taiwan seeks to develop informational superiority in its own waters — documenting every CCG maneuver, every order directed at a commercial vessel, every incursion into Taiwan's exclusive economic zone.

Electronic warfare and information in the strait

Beyond drones, the information war is a crucial front in the China-Taiwan confrontation at sea. China uses CCG radio communications to broadcast its jurisdictional claims — messages that Taiwan systematically countered with its own radio communications to affected vessels. This battle of the airwaves is, in the immediate term, more significant than any physical exchange: it is a war of narrative normalization where the party that repeats its position most frequently ultimately comes to be perceived as the legitimate actor.

The Taiwan Coast Guard broadcast its counter-messages in English, Mandarin, and other languages for the crews of international commercial vessels queried by the CCG. These counter-messages, documented and distributed to international media, serve to demonstrate that China is operating in waters where its jurisdiction is not recognized. This is a form of documentary resistance that prepares the ground for the international legal arguments Taipei intends to advance if the crisis deepens.

Implications for global maritime trade: economic stakes

The impact on maritime insurers and shipowners

The CCG's operations east of Taiwan have economic consequences extending well beyond regional politics. Maritime insurers — Lloyd's of London and major Asian insurers — are watching the situation closely to assess the risk level of routes passing east of Taiwan. If CCG incidents multiply, if vessels are boarded or delayed, insurance premiums could rise — an increase that passes through to global trade costs.

This economic mechanism is precisely the long-term objective of a gradual pressure strategy: make the commercial routes east of Taiwan perceived as riskier, force shipowners to seek Beijing's permission to reduce that risk, and thereby progressively establish de facto jurisdiction without a formal blockade declaration. The Singaporean, Liberian, and Beninese vessels queried in June 2026 each transmitted a signal to their owners: the waters east of Taiwan now carry the risk of interaction with Chinese authorities.

The cost of economic silence for the West

The West has a direct economic interest in freedom of navigation east of Taiwan. Taiwan is the world's leading producer of advanced semiconductors — TSMC and its peers produce more than 90 percent of the world's most advanced chips. A Taiwanese blockade would not only be a geopolitical catastrophe — it would be a global economic catastrophe. The automotive industries, consumer technologies, and weapons systems of all Western democracies depend on Taiwanese components.

This dependency creates a Western economic interest in strait stability that transcends abstract geopolitics. American and European technology companies — Apple, NVIDIA, AMD, European automotive giants — have an existential stake in freedom of navigation east of Taiwan. This concrete economic interest should reinforce Western political will to resist CCG provocations — because the cost of inaction is measured not only in democratic values but in global supply chains and economic prosperity.

Taiwan's civil mobilization: a democracy preparing itself

Civil society facing the blockade threat

Beyond the institutional responses of government and armed forces, Taiwan's civil society has mobilized with remarkable maturity in the face of intensifying Chinese provocations. Civil emergency preparedness organizations — originally created for natural disasters in this seismically active country — have expanded their mandate to include blockade or conflict scenarios. Simulations of food self-sufficiency, fuel stock management, and communication organization in the event of submarine cable severance have been conducted in several cities.

This civil preparedness is not paranoia — it is a rational response to a documented risk. President Lai Ching-te personally opened the resilience committee meeting on June 25, 2026 that simulated a blockade scenario. His message to Taiwanese citizens is clear: defending Taiwan is not solely the military's affair — it is a collective responsibility of every citizen. This approach to total defense, inspired by the Finnish and Nordic model, seeks to transform social resilience into a deterrent factor in its own right.

The Ukrainian model as inspiration for Taiwanese resilience

Ukraine's resistance to the Russian invasion since 2022 has profoundly influenced Taiwanese civil preparedness. Ukraine's ability to maintain government functions, organize logistical resistance, and communicate with the world despite strikes on infrastructure — all of this has been studied carefully in Taipei. Concrete decisions followed: energy reserve diversification, development of Starlink communication systems as alternatives to submarine cables, and strengthening of strategic stockpiles of essential goods.

Perhaps the most profound Ukrainian lesson is the simplest: a population determined to defend its freedom is a considerable force multiplier. Ukrainian defenses held because Ukrainians wanted to resist — not only because they had weapons. Taiwan, with its developed democratic culture and growing awareness of the Chinese threat, possesses that capital of determination. Developing, maintaining, and strengthening it is one of the most important strategic priorities of the Lai government.

Conclusion: Naming the legal vise before it closes

The moment of clarity

What China is doing east of Taiwan in June 2026 deserves to be named clearly, without the diplomatic euphemisms that soften the message: it is a progressive construction of de facto legal claims designed to facilitate a future coercive operation. The CCG patrols, the merchant vessel queries, the "nearshore governance" claims — all of this charts, with methodical precision, the contours of a future Chinese control zone that Beijing intends to invoke when the moment comes.

The appropriate response is neither hysteria nor passivity — it is clarity. Name what China is doing. Resist each encroachment with a proportionate and collective response. Maintain freedom of navigation through real patrols, not just declarations. Support Taiwan with credible military capabilities. And do not repeat the Ukrainian mistake of letting warnings multiply without responding to them sufficiently early and firmly.

The hour of choice for the democracies

The hour of choice for Western democracies is not ten years from now, when the crisis will be open. It is now, while CCG patrols are still a "special operation" and not an established permanent presence. The joint statement by the four powers on June 24, 2026 is a good start — but only a start. It must be followed by action: regular and coordinated freedom-of-navigation patrols in the affected waters, an explicit refusal to normalize CCG conduct, enhanced support for Taiwanese defense capabilities, and a clear message to Beijing that the strategy of progressive encirclement has been identified, named, and will not be tolerated. Before the vise closes.

By Maxime Marquette, columnist

Columnist's transparency note

Position and convictions

I am openly pro-democratic and in favor of maintaining the status quo in the Taiwan Strait. I believe Taiwan's democracy deserves to be defended, and that Beijing's strategy of progressive encirclement is a real threat to the liberal international order. These convictions are transparent and argued — they do not prevent me from examining counterarguments and the uncertainties in my analysis.

Despite this declared position, I have made every effort to present the Chinese Coast Guard's actions factually, sourced to primary documents. Readers who assess Chinese intentions differently are encouraged to consult the ISW and Defense News analyses cited in the Sources section.

What I do not know

I do not have access to classified assessments of Beijing's intentions regarding Taiwan. The interpretations of Chinese strategy I propose — notably the link between CCG patrols and preparation for a possible blockade — are analytical inferences based on public sources, not certainties. It is possible that CCG activities in June 2026 are more limited in their objectives than what I analyze here. I hope so — but analytical prudence suggests taking the most unfavorable scenarios seriously.

The analytical scenarios I describe are possibilities derived from public evidence, not certainties. Responsible analysis of authoritarian state behavior requires taking worst-case scenarios seriously without asserting them as inevitable.
