ANALYSIS: Scarborough—Beijing Extends Its "Gray Coercion" to the Skies

Three Devices, a Made-Up Border

The Phrase That Shakes the Heavens

Three small Philippine aircraft. That is the number around which Beijing, on August 21, built a sovereignty claim and issued a military warning over the Scarborough Shoal. The Chinese military claims to have tracked them and ordered them to leave after what it described as an illegal entry. The exact flight path has not been made public. Manila had not yet provided a documented response at the time of the report.

This gap does nothing to soften the situation. It merely forces us to reconcile two truths: the incident remains only partially established, but China’s claim, for its part, is perfectly clear.

The decisive word is not “three.” It is not even “aircraft.” It is “airspace.” From the moment a power treats the sky over a disputed shoal as the natural vertical extension of its territory, it is no longer merely describing a passage. It is drawing a border, then demanding that others behave as if that border had always existed.

The Warning Before the Interception

A radio warning may seem insignificant compared to a water cannon, a collision, or an injured sailor. That is precisely what makes it useful in a strategy of gray coercion: the act remains below the threshold of war, but it alters the expected behavior of the recipient.

The pilot must decide. To continue is to risk a closer interception. To turn back is to let the warning set a practical precedent. Between these two options, a few seconds may be enough to turn a routine mission into a military calculation.

Beijing does not need to officially close the airspace. It need only make each crossing more costly, more nerve-wracking, and less frequent. A repeatedly enforced boundary sometimes comes to resemble a recognized border, even when no treaty has enshrined it.

Gray coercion often begins with a statement that the other side is summoned to take seriously.

Scarborough is no docile island

A reef at the center of a massive power struggle

Scarborough is a low-lying, disputed atoll located in the South China Sea. The Philippines call it Bajo de Masinloc or Panatag. China calls it Huangyan Dao. Names are not mere embellishments here: they carry maps, national narratives, claimed rights, and years of confrontation.

The arbitral tribunal established under the United Nations Convention on the Law of the Sea issued its final award on July 12, 2016. It concluded that Scarborough is a rock in the legal sense and does not generate its own exclusive economic zone. It also found that Filipino, Chinese, and other fishermen had historically engaged in traditional fishing there.

The law has not erased power. It has merely stripped power of the pretext of legal certainty—a pretext that power nevertheless continues to invoke on the water and now in the sky.

Control Without Recognized Sovereignty

Since 2012, China has maintained a dominant presence around the reef. This de facto control does not settle the issue of territorial sovereignty. It reveals something else, something more brutal: in a disputed area, the one who remains can impose rules on the one who must leave.

This is where the vocabulary of “intrusion” becomes a weapon. It transforms the other claimant into a trespassing visitor. It converts an unresolved dispute into an already established order. And it places on Manila the burden of proving, mission after mission, that it has not given up.

Scarborough is therefore not just a point on a map. It is a workshop where tomorrow’s strategic normality is forged.

The reef is shallow. The battle to define what looms over it, however, is intensifying.

From Hull to Wing

The Continuity of a Method

Chinese pressure around Philippine positions did not begin on August 21. Incidents have mounted: blockades, close-range maneuvers, water cannons, mutual accusations, and naval and aerial patrols. At Second Thomas Shoal, the Associated Press reported in July that a Filipino sailor had been injured during a confrontation, while Beijing accused Philippine vessels of ramming a Chinese ship.

Each incident has its own facts and points of contention. To conflate them would be lazy. Linking them, however, reveals a pattern: increasing the number of contested encounters, imposing one’s own narrative, and then portraying the adversary’s presence as the source of danger.

What is new about Scarborough is not the existence of coercion. It is its escalation: the same logic moves from the hulls of ships to the heights of aerial patrols.

A Third Dimension to Manage

At sea, a collision leaves images, marks, and sometimes debris. In the air, the margin for error is narrower, and public evidence is often scarcer. Altitude, distance, speed, and angle of approach become essential; yet, this data is not always immediately available.

This lack of transparency favors whoever speaks first. A military statement can set the framework before technical evidence is released. The debate then begins with the words chosen by the power that issued the warning.

Moving from the maritime to the aerial realm thus adds not only a domain of action but also a domain of narrative.

When the pressure shifts to the skies, even the slightest misunderstanding loses the breathing room it needs.

The danger lies in the calculation

The mistake no one intends

China itself has cited the risk of misunderstanding and miscalculation. This phrase deserves to be directed back at the mechanism that produces it. The more warnings, interceptions, and disputes surrounding a single area there are, the more opportunities there are for a crew to misinterpret an intention.

Neither side needs to want a collision for one to become possible. All it takes is imperfect communication, a maneuver perceived as hostile, or a distance assessed differently. In the air, the diplomat’s time comes after the pilot’s.

The real danger isn’t just a decision to go to war made in a capital city. It’s a chain of tiny, compressed decisions, in which each side believes it is preventing the other from advancing.

The Paradox of the Warning

Beijing presents its warning as a control measure. Manila may see it as an attempt to expel it from a space it considers linked to its rights and claims. The same message is intended to be stabilizing for one and coercive for the other.

Herein lies the paradox: the more a power wants to demonstrate that it is in control, the closer it must get; the closer it gets, the more it creates the very danger it claims to be managing.

Stability is not measured by the number of incidents avoided so far. It is also measured by the number of times crews are forced to improvise on the brink of an incident.

You can avoid an accident a hundred times and still have built the road that leads to it.

The gray area has a very distinct color

Staying Below the Threshold

Gray coercion exists between comfortable peace and open attack. It uses military or paramilitary means but seeks never to provide the adversary with the simple provocation that would trigger a simple response. No declaration of war. No announced conquest. Actions strong enough to shift reality, yet limited enough to complicate a counterattack.

An aerial warning fits perfectly into this strategy. It destroys nothing. It does not, on its own, prove a lasting shutdown. Yet it signals who claims the right to say yes or no.

The gray zone is not vague to those who practice it. It is calibrated: take a little, test a lot, and leave the apparent responsibility for any escalation to the other side.

The Price of the Opponent’s Patience

Every time the Philippines chooses restraint, it protects lives and avoids a spiral of escalation. This restraint is necessary. But it can also be exploited if it comes without a military presence, without public evidence, or without credible allied support.

Coercive power then relies less on a spectacular victory than on attrition. Patrolling costs money. Documenting costs money. Protesting costs money. Returning again costs money.

Normalization advances when the cost of challenging the status quo becomes a daily reality and the benefit of resistance remains abstract.

The strategy does not require Manila to capitulate; it merely requires Manila to hesitate more often.

The Fisherman Beneath the Map

Rights That Don’t Fly

Big words—sovereignty, jurisdiction, deterrence—float easily above the reef. Beneath it lies fishing. The 2016 arbitral award recognized the traditional nature of this activity for fishermen of various nationalities and criticized China for preventing Filipino fishermen from accessing the area after May 2012.

The August 21 incident involved aircraft, not fishing vessels. It would be wrong to claim to know the immediate impact on any particular fishing trip. But the general mechanism is clear: aerial surveillance reinforces monitoring and intimidation around an already disputed maritime area.

For fishermen, a sovereignty line is never just a line. It is the ability to set out, return, and work without becoming an unwitting pawn in a military confrontation.

Safety Before Fish

When patrols become more frequent, the civilian calculus changes. The presence of military aircraft, coast guard vessels, and rival ships does not automatically turn every fishing trip into a danger, but it adds a layer of uncertainty to an activity that already carries enough of it.

The contested sea is then measured in uncertain income, altered routes, and areas that are familiar but where one can no longer be sure of being left in peace.

The first victim of an artificial border is often one’s way of life.

The law doesn’t fly any planes

The 2016 Award and Its Limits

The arbitral award constitutes a major milestone. It rejected the legal basis for China’s broad “historic rights” beyond what is permitted by the Convention and detailed the status of several maritime features. China has not accepted this award and continues to reject it.

We must keep these two facts separate: the award is legally binding on the parties according to the tribunal; it has no inherent power to turn a ship away or guide an airplane.

The law dictates where power should stop. It has neither an engine, nor radar, nor a crew to enforce this when power decides to press ahead anyway.

The Test of Repetition

An international rule survives less by the beauty of its text than by the steadfastness of those who invoke and embody it. If states cease to base their conduct on it, the rule remains on paper, but its effect diminishes.

That is why a patrol matters. An official protest matters. The publication of flight data matters. None of these alone resolves the conflict, but each prevents the opposing claim from becoming the only version put into practice.

The risk is confusing patience with passivity.

A ruling that is ignored does not become wrong; it becomes a test for all those who claim to believe in the rules.

The U.S. alliance enters the cockpit

A guarantee that must remain clear

The Mutual Defense Treaty between the Philippines and the United States dates back to 1951. It stipulates that each party would respond to an armed attack in the Pacific region in accordance with its constitutional procedures. In a series of official statements, Washington has reaffirmed that Philippine armed forces, government vessels, and aircraft in the Pacific—including in the South China Sea—fall within the scope of this guarantee.

But a radio warning is not an armed attack. That is precisely the point of the gray zone: to act in the space that exists before an alliance is clearly triggered.

A guarantee designed for the moment a shot is fired must also learn to deter the myriad actions that seek precisely to ensure that shot is never fired.

Presence, Clarity, Discipline

The joint U.S.-Philippine patrols near Scarborough Reef demonstrate one possible response: visible presence, coordination, and training. They can bolster Manila’s confidence and signal that the area will not be abandoned by default.

They can also increase the military presence around the reef. Deterrence therefore requires strict discipline: clear communications, well-defined rules of engagement, prompt disclosure of facts, and a refusal to engage in theatrical maneuvers that would give Beijing a narrative of encirclement.

The alliance must be firm without becoming frantic. Its goal is not to win this round. Its goal is to prevent the next round from being more dangerous.

An ally’s credibility is not proven by shouting the loudest, but by being there without losing one’s head.

Beijing is manufacturing a sense of normalcy

Name, patrol, repeat

Chinese power often operates through accumulation. A so-called routine patrol. A warning. A new map. A declaration of sovereignty. Taken separately, each move can be presented as defensive or administrative. Together, they form an architecture of control.

The Chinese Ministry of Defense regularly highlights naval and air patrols in the South China Sea. This visibility serves two audiences: the outside world, which must acknowledge China’s capabilities; and the domestic audience, which must see the state defending what it presents as its own.

Repetition achieves what a single proclamation could not: it transforms a contested claim into a permanent backdrop, and then that backdrop into a political norm.

Sovereignty Through Words

To say that an aircraft entered “without permission” presupposes that Chinese permission was necessary. The entire dispute lies hidden within this presupposition.

Official language functions as a portable border. It follows ships, boards airplanes, and enters news dispatches.

Rejecting this framing does not mean denying the risk or exonerating Manila. It means demanding details on flight paths, distances, communications, and the rules invoked before accepting the verdict contained in the first statement.

Whoever dictates the language of the incident is already beginning to dictate its geography.

What Manila Must Demonstrate

Evidence as an Instrument of Sovereignty

The Philippines cannot respond with indignation alone. They must respond with publishable facts: flight plans, radio recordings, images, schedules, mission objectives, and crew conduct. Not to satisfy Beijing, but to prevent a lack of transparency from working against them.

If the aircraft followed a route consistent with the Philippine position and applicable law, the world must be able to verify it. If a mistake was made, Manila must also acknowledge it. Credibility is not a uniform one puts on; it is a discipline that survives adverse facts.

The side we support is not entitled to a more flexible version of the truth. It needs a more solid truth, because its adversary turns every gray area into room for maneuver.

Ensuring a Sustainable Presence

Sovereignty and maritime rights are not defended by a single spectacular flight. They are defended by a regular, civilian and military presence, supported by institutions capable of documenting events without improvising.

This requires well-maintained aircraft, trained crews, equipped coast guards, responsive diplomacy, and an alliance that does not discover a crisis only when it erupts.

The power gap with China will not disappear. But the gap between vulnerability and preparedness can be narrowed.

A small power does not become great by exaggerating; it becomes resilient by proving itself, returning, and holding its ground.

What Washington Can No Longer Put Off

Deterrence Before Collision

The United States has an interest in avoiding two opposing failures. The first would be silent abandonment: repeatedly reaffirming the treaty while allowing sub-threshold actions to redraw the landscape. The second would be escalation: responding to every warning as if war had already begun.

Between the two lies the difficult work: shared surveillance capabilities, low-key exercises, crisis communications, support for coast guards, rapid dissemination of verifiable facts, and clarity on the behaviors that would trigger a response.

The best crisis is one that the adversary refrains from provoking because they know the cost—not one that an ally improvises after discovering that no one had defined that cost.

The promise must trickle down to the field

An alliance exists on paper, but it lives in procedures. Who calls whom? What data is shared? At what point does an interception become a serious threat? Who speaks publicly, and with what evidence?

These questions seem technical until the day a pilot no longer has time to ask them. Resolving them calmly is a form of courage less photogenic than sending a fighter jet, but often more useful.

The open West does not defend itself with slogans of firmness. It defends itself with mechanisms that make firmness predictable and error less likely.

A vague guarantee reassures the rhetoric; a clear procedure reassures the one who flies.

ASEAN Faced with Its Own Silence

A Bilateral Conflict Spilling Over

Scarborough directly pits China against the Philippines, but the stakes extend beyond these two states. If a claim backed by a superior military presence can become the norm, every coastal country in the region must assess what that means for its own disputes.

The Association of Southeast Asian Nations has been seeking a code of conduct in the South China Sea for years. Negotiations are difficult; in the meantime, practices take hold.

The regional vacuum is never empty. It is occupied by the actor that possesses the ships, the aircraft, the endurance, and the will to repeat its version until the others are worn down.

Impossible Unity, Necessary Coordination

ASEAN members do not share the same interests, the same disputes, or the same economic relationship with Beijing. A perfectly unified position is therefore difficult to achieve. This difficulty must not become an excuse for the absence of minimum rules.

The region does not need a show of unity. It needs joint actions concrete enough that crews know an incident will not be swept under the rug by cautious press releases.

When unanimity becomes impossible, the common minimum ceases to be small.

China, too, stands to lose

The victory that brings neighbors closer

Beijing holds the material advantage around Scarborough. But coercion comes at a political cost. The more incidents recur, the more the Philippines seeks joint patrols, access agreements, equipment, and increased cooperation with the United States and other partners.

This is China’s strategic paradox: gaining tactical ground while simultaneously strengthening the very coalition it denounces. A power can force a local withdrawal and, in the same breath, lose some of its regional credibility.

Every warning may drive an aircraft away. It may also bring an ally closer, harden a doctrine, fund a radar system, and convince a generation of Filipinos that dependence on Beijing is a risk.

Restraint as a Potential Strength

This alternative path, however, requires Beijing to accept an idea it often opposes in its disputed peripheries: power alone does not confer the final say.

De-escalation would not be a historic retreat. It would be proof that a great power knows how to distinguish between control and security.

China can dominate the reef and still limit its regional future.

Six Things to Watch Now

Signs of escalation

First, whether or not the Philippines releases data on the three flights. Second, the occurrence of physical interceptions rather than mere warnings. Third, the frequency of announced Chinese patrols around the reef.

Fourth, the allied response: a new joint flight, naval presence, a coordinated statement, or silence. Fifth, any changes in fishermen’s access. Sixth, whether a crisis channel is actually being used rather than merely promised.

These six elements carry more weight than adjectives. They will determine whether August 21 remains a disputed incident or becomes the visible beginning of de facto airspace control.

What We Still Don’t Know

We do not publicly know the exact flight path of each aircraft, the distance from Chinese assets, the full content of radio exchanges, or the Philippine government’s official assessment of the incident. Nor do we know whether Beijing will quickly repeat the same pattern.

These unknowns prevent us from declaring that a no-fly zone already exists. They do not prevent us from seeing the pattern: Beijing has asserted the right to authorize, monitor, and issue warnings over a disputed area.

Vigilance begins precisely there: not turning a signal into certainty, but not waiting for certainty when the signal points to the possibility of a collision.

This is not yet a recognized new frontier. It is a recurring new frontier.

The sky is not a press release

Three Returns

Three aircraft. At first, the number seemed almost small. In the end, it signifies something else: three instances in which crews were placed in the midst of a sovereignty dispute that neither their size nor their mission could resolve.

The record remains incomplete. Caution dictates that we say so. But caution does not require blindness. The Chinese statement places Scarborough’s airspace on the same continuum of control as the surrounding waters.

It doesn’t take a missile to shift the regional order. Sometimes, all it takes is a radio command, repeated often enough that the recipient begins to ask for permission to exist.

Reject Accidents, Reject Subjugation

The Philippines must avoid gratuitous provocation. China must stop presenting its disputed claim as an indisputable authority. The United States must provide targeted support without turning every patrol into a spectacle. ASEAN must establish safeguards even if it cannot call the shots.

All of this is less satisfying than a grand verdict. Yet it is the work that prevents a warning from becoming an interception, then a collision, then a military necessity.

The sky above Scarborough cannot be left to the whim of whoever speaks first. It still belongs to the dispute, to the law, to the evidence, and to the military restraint of those who reject both war and erasure.

How many warnings will it take before the world understands that a habit is already becoming a map?
