134 Chinese Air Incursions Into Taiwan's Defense Zone in June

Introduction: the dangerous normalization of Chinese pressure

A number that masks a strategy

The Institute for the Study of War confirmed, in its update dated July 2, 2026, that the Chinese military carried out 134 air incursions into Taiwan's air defense identification zone during the month of June alone. At first glance, the number might seem reassuring compared with the more than 300 monthly incursions recorded after President Lai Ching-te's inauguration in May 2024. But this apparent decline hides a far more troubling reality.

Because while air incursions statistically decline, the carrier Fujian, the Chinese navy's newest, sailed through the Taiwan Strait on June 23, 2026 for the third time in less than a year. This combination of signals — fewer air incursions but more sophisticated naval presence — points to a methodical pressure strategy, not an easing of tensions.

The cold calculus behind the drop in incursions

A tactical pause, not a de-escalation

According to the ISW's analysis, the decline in the monthly volume of People's Liberation Army sorties since the start of 2026 likely reflects an adjustment in Beijing's coercion strategy toward Taiwan, rather than a seasonal fluctuation or a temporary factor. Twelve days in June even passed without a single incursion crossing the strait's median line — a notable fact given the pattern of the past three years.

Another explanation offered by analysts: the Chinese military may have reduced its sortie count to carry out maintenance on its air fleet after a prolonged period of intensive use. But whatever the exact cause, the intended effect remains the same: desensitize Taiwan to repeated air intrusions, gradually eroding its vigilance over time.

The carrier Fujian, symbol of a growing power

Three crossings in less than a year

The Fujian, commissioned in November 2025 and fitted with next-generation electromagnetic catapults, sailed through the Taiwan Strait for the third time on June 23, following crossings in September and December 2025. Beijing consistently describes these crossings as "routine and standard training," a phrase repeated by Defense Ministry spokesman Senior Colonel Zhang Xiaogang.

But the timing is never neutral. This crossing came a day after the start of Taiwan's annual immediate-combat-readiness exercises, suggesting a calculated response rather than a scheduling coincidence. The Fujian's crew reportedly tested equipment "put into practice for the first time," according to details reported by the ISW.

Three carriers, doubled capability

A rotation that changes the strategic equation

With three carriers now in service — the Fujian, the Liaoning, and the Shandong, the latter currently under maintenance since January — the Chinese navy has unprecedented operational flexibility. The ISW notes that the Chinese military previously could not keep two carriers deployed at once, but could now manage it with three vessels in constant rotation.

In practice, this would mean one carrier could always be in maintenance, a second held in reserve at port, and a third deployed at sea, enabling far more frequent and sustained deployments around Taiwan. The Liaoning's return to the Northern Theater Command after exercises in the South China Sea and the western Pacific illustrates this new rotation mechanism.

The gray-zone war of the Chinese coast guard

Methodical, documented maritime pressure

Beyond aviation and the navy, the Chinese Coast Guard has stepped up efforts to erode Taiwan's control over waters east of the island and around its outlying islands. Three intrusive patrols targeted the restricted waters around Pratas Island on June 5, 19, and 27, while four more patrols targeted waters around Kinmen on June 3, 16, 18, and 29.

A troubling detail noted by Taiwan's coast guard administration: during the June 5 patrol, a Chinese research vessel coordinated its movements with the coast guard for the first time. At least two Chinese coast guard vessels have also patrolled continuously in the eastern exclusive economic zone claimed by Taiwan since June 1, a permanent presence that did not exist before.

Toward a model of generalized blockade

Kinmen and Pratas as laboratories

According to Chinese state media cited by the ISW, the "model" of asserting maritime jurisdiction around Kinmen and Pratas Island could be extended to all of Taiwan. The Wall Street Journal reported on June 19 that China now maintains a near-constant naval presence of five to six warships around Taiwan at any given time in 2025, compared with just one ship patrolling the strait in 2020 — a five- to six-fold increase in just five years.

During a five-day patrol, coast guard and law enforcement vessels hailed three passing merchant ships and claimed to have inspected 198 vessels to assert Beijing's jurisdiction. These figures, combined with joint exercises conducted by the Chinese navy and coast guard in April and December 2025 to practice imposing a maritime blockade, point to a methodical preparation for a quarantine or blockade scenario.

What the West must understand before it's too late

A closing window for deterrence

Normalizing an elevated military and paramilitary presence all around Taiwan is precisely Beijing's strategic objective: making every new escalation less shocking than the last, until an actual blockade no longer draws the international reaction it would deserve. The capabilities tested during these patrols — maritime traffic control, vessel inspection, interagency coordination — are exactly what would be needed to impose a blockade or quarantine aimed at forcing a political "reunification."

Faced with this reality, documented by sources as rigorous as the ISW and the Wall Street Journal, Western democracies can no longer afford to wait and see. Every incursion, every intrusive patrol, every carrier crossing labeled "routine" must be called what it is: one more step toward coercive control of Taiwan.

Regional allies facing a strategic dilemma

Strengthened military coordination

American armed forces are ramping up joint exercises with their regional partners, notably through combined naval patrols in the South and East China Seas. This coordination is meant to demonstrate a fast, unified response capability against any attempt by Beijing to impose a military fait accompli in the region.

Defense analysts note that this coordinated Western presence remains, for now, the primary deterrent factor preventing a faster escalation by China toward Taiwan and its neighbors.

Japan and the Philippines on the front line

The pressure on Taiwan does not unfold in isolation. Japan and the Philippines, both strategic U.S. allies in the region, are watching the intensification of Chinese military activity with growing concern, aware that a blockade or conflict scenario around Taiwan would have direct repercussions for their own maritime security and essential trade routes.

This strategic interconnection explains why Washington maintains close coordination with Tokyo and Manila on regional security matters, reinforcing joint patrols and shared military exercises. The normalization of Chinese pressure around Taiwan serves, for these allies, as a direct warning about their own future vulnerability.

Conclusion: document it so it is never normalized

An accumulation of facts, not a theory

The134 air incursions in June, the Fujian's third crossing, the multiple intrusive patrols around Kinmen and Pratas, the five-fold increase in naval presence since 2020: each of these facts, taken alone, might seem minor. But their accumulation, documented month after month by independent organizations like the ISW, traces a clear and troubling trajectory.

Taiwan remains a vibrant democracy, an essential strategic ally of the West in the Pacific, and its sovereignty must never be treated as negotiable in the face of Beijing's coercive pressure. Rigorously documenting every incursion, every patrol, and every naval maneuver is not an alarmist exercise: it is the bare minimum needed to prevent the normalization of gradual aggression.

Every democracy watching this unfold should ask itself a hard question: what happens the day the counting stops mattering, the day the world simply shrugs at another logged incursion because the pattern has become background noise? That is precisely the outcome Beijing is patiently engineering, and it is precisely the outcome independent documentation exists to prevent.

Columnist's transparency note

Who I am and my acknowledged biases

I am a pro-Western, pro-Taiwan columnist, convinced that China represents a major strategic threat to the rules-based international order. This article relies on analyses from the Institute for the Study of War, an organization recognized for the rigor of its military assessments, as well as on verifiable reporting from Reuters and the Wall Street Journal.

I have no privileged information about Beijing's exact intentions, and I avoid any speculation not grounded in facts documented by the reliable sources cited below.

What I don't know

I do not know whether the decline in air incursions will continue in the months ahead, nor whether it will be offset by an intensification of other forms of pressure, such as maritime patrols. Nor do I claim to know the exact timeline of any major escalation by Beijing toward Taiwan — no one outside China's decision-making circle knows that with certainty.
