Each incursion shifts the facts on the ground
In the East China Sea, two nations circle a cluster of uninhabited islands that carry the weight of sovereignty, history, and strategic ambition. Beijing extended a quiet gesture of restraint ahead of a rare diplomatic summit, only to see it undone by the entry of Japanese fishing boats into contested waters — and the cycle of provocation resumed. What analysts observe is not mere reaction, but a patient, incremental strategy by China to normalize its presence until the question of who controls the Senkaku Islands becomes, in practice, unanswerable.
- China's rare withdrawal of naval forces from disputed waters — a diplomatic signal ahead of a historic presidential visit — collapsed the moment Japanese fishing boats crossed into the contested zone.
- What resumed was not simply tension but a deliberate pattern: Chinese law-enforcement vessels returning in force, each deployment quietly expanding the baseline of what counts as normal Chinese presence.
- Experts warn this 'salami-slicing' strategy unfolds in three phases — normalize, enforce, then challenge administrative control — and the first phase is already well underway.
- Japan's ruling party lawmakers are pushing back with calls for joint US military drills, surveillance drones, and amphibious capabilities, raising the stakes of what was once a low-intensity standoff.
- A quieter school of thought in Tokyo argues that coastguard patrols and a firm American commitment may be sufficient — and that militarizing the response risks accelerating the very escalation it seeks to prevent.
In the East China Sea, Beijing made a calculated gesture of restraint. In the months before what would have been the first Chinese presidential visit to Japan since 2008, China quietly reduced its naval presence near the disputed Senkaku Islands — a signal, however unspoken, that it preferred stability over confrontation at a moment when its relations with Washington were already strained. Pushing Japan closer to the United States served no one in Beijing's interest.
Then Japanese fishing boats entered the disputed waters, and the restraint dissolved. Chinese maritime activity resumed, and with it came a pattern that analysts found more troubling than simple escalation. Alessio Patalano of King's College London described a strategy of 'routinisation' — each Chinese deployment normalizing the last, each incursion quietly redrawing the practical boundaries of control. The goal, he argued, was not immediate confrontation but a gradual erosion of Japan's administrative grip on the islands across three deliberate phases.
The final phases — asserting law-enforcement rights and directly challenging Japanese control — remained distant and, by most accounts, undesired by either side. Yet the momentum was real. Japanese lawmakers from the ruling Liberal Democratic Party called for joint defense drills with the United States and accelerated investment in surveillance and amphibious capabilities. Others, including professor Sato Yoichiro, urged a more measured response: stronger coastguard patrols and a reaffirmed American commitment might be enough.
What made the cycle so difficult to break, observers noted, was its self-reinforcing logic. Each act of restraint went unrewarded; each provocation confirmed the other side's suspicions. China was escalating at precisely the moment it could least afford to push Japan deeper into Washington's embrace — and yet, that is exactly what was happening.
In the waters of the East China Sea, where the Senkaku Islands sit disputed between two nations, a quiet diplomatic gesture went unreciprocated. Beijing had made a calculated move: in the months leading up to what would have been the first visit by a Chinese president to Japan since 2008, China had substantially withdrawn its naval presence from the contested waters. It was, by most measures, an olive branch—a signal that Beijing wanted to avoid escalation at a moment when tensions with Washington were already running high.
Then Japanese fishing boats entered the disputed waters, and the fragile restraint collapsed. What followed were skirmishes between the two sides, and China's maritime activities in the area resumed with renewed intensity. Liu Qingbin, an associate professor at Yokohama National University, observed this cycle with concern. He understood the logic behind Beijing's initial pullback: antagonizing Japan while simultaneously managing deteriorating relations with the United States would only drive Tokyo closer to Washington's orbit, tightening an alliance that already constrained Chinese ambitions in the region.
But the pattern that emerged suggested something more deliberate than simple tit-for-tat escalation. Alessio Patalano, an East Asian security expert at King's College London, identified what he called a "routinisation" of Chinese deployments—what others have termed a salami-slicing approach. China was not simply asserting its presence; it was normalizing it. Each incursion, each extended stay in the disputed waters, each deployment of law-enforcement vessels served a purpose: to establish a baseline of Chinese activity that would gradually shift the facts on the ground. Patalano described this as the first phase of a three-pronged strategy: normalize presence, exercise law-enforcement rights, and ultimately challenge Japan's administrative control of the islands.
The second and third phases, however, carried risks that neither Beijing nor Tokyo appeared willing to accept. A full escalation toward armed conflict would be catastrophic for both nations, and Patalano acknowledged that the final phase was far from inevitable. Yet the momentum was unmistakable. In response, lawmakers from Japan's ruling Liberal Democratic Party called for joint defense drills with the United States in the East China Sea, along with accelerated development of surveillance drones, amphibious vehicles, and other weapons systems designed to strengthen Japan's grip on the islands.
Not all Japanese analysts saw this as necessary. Sato Yoichiro, a professor at Ritsumeikan Asia Pacific University specializing in security policy, argued that Japan could maintain adequate deterrence through simpler means: increased coastguard patrols and a reliable American commitment to its defense obligations. The question of whether Japan should formalize its military posture with the US remained contested among experts. Mike Mochizuki, an international affairs professor at George Washington University, found it puzzling that China would choose this moment to escalate—when doing so would only tighten the very alliance that constrained Beijing's options. Yet that is precisely what was happening: a cycle of restraint and provocation, each side reading the other's moves as confirmation of hostile intent, each response narrowing the space for de-escalation.

Why would China pull back its naval presence if it was just going to resume operations anyway?
Because the timing mattered. Xi was supposed to visit Japan—the first presidential visit in over a decade. Beijing was signaling that it could be a responsible actor, that it wanted better relations. It was a test.
And Japan failed the test by sending fishing boats?
That's one way to read it. Or Japan saw the pullback as weakness and moved to consolidate control. Either way, the moment of restraint was brief.
This "salami-slicing" strategy—is that new?
Not entirely. But what's different now is the consistency. China isn't just showing up occasionally. It's establishing a permanent presence, normalizing it. Each patrol makes the next one seem more routine.
Does Japan have a good counter to that?
The experts disagree. Some say more patrols and US support are enough. Others want formal military drills. But the real problem is that every response China sees as provocation, and vice versa.
So this ends in conflict?
Not necessarily. Both sides understand the costs would be catastrophic. But understanding that and actually stepping back are two different things.
