China's 'Salami-Slicing' Strategy Expands Control Beyond First Island Chain

If they lied before, they can lie now
Philippine Defense Secretary Gilbert Teodoro on China's pattern of breaking commitments regarding military bases in the South China Sea.

In the waters east of Taiwan, China's civilian maritime vessels have crossed a threshold that military ships could not so easily breach — sailing beyond the First Island Chain for the first time to map seabeds and challenge commercial traffic, all under the banner of routine governance. This is the logic of incremental conquest: not a single dramatic act, but a patient accumulation of presence, precedent, and language until sovereignty becomes a fait accompli. What Beijing calls nearshore waters, the rest of the world has long understood as international sea — and the distance between those two definitions is where the future of Taiwan, and perhaps the broader Pacific order, is quietly being decided.

  • Chinese civilian vessels crossed the First Island Chain for the first time, conducting seabed mapping east of Taiwan and issuing radio challenges to commercial ships — a move analysts call the 'Bashi Breakout.'
  • By using Maritime Safety Agency ships rather than warships, Beijing normalizes a constabulary presence in contested waters while avoiding the optics of outright military aggression.
  • Taiwan's president and security officials recognized the operation as a deliberate attempt to manufacture de facto jurisdiction, warning that energy supply lines — particularly liquefied natural gas — could become leverage for coercion.
  • At Scarborough Shoal, a mysterious floating structure appeared near the lagoon entrance before being towed inside, echoing the pattern by which China transformed South China Sea reefs into military installations despite explicit pledges not to.
  • Britain, France, Germany, and the United States issued formal objections, while the Philippines received $13 million in surveillance drones — but analysts warn the gravest risk is a global shrug that lets the last slice of salami disappear uncontested.

In the spring of 2026, three ships from China's Maritime Safety Agency sailed through the Bashi Channel between the Philippines and Taiwan and continued east of the island — the first time these civilian vessels had crossed the First Island Chain, the arc of islands long treated as a psychological and strategic boundary in the western Pacific. Beijing framed the mission as routine mapping and research. Analysts called it something else: the 'Bashi Breakout,' a calculated assertion of jurisdiction over waters where China's legal claims have no foundation under international law.

What made the move significant was not just geography but language. Through a state broadcaster's social media account, China described the waters east of Taiwan as 'nearshore waters' where it 'maintains presence and exercises governance.' If that framing migrates into official policy, it could allow Beijing to treat those seas as sovereign territory — barring foreign vessels without permission. Taiwan's President Lai Ching-te was direct: 'Their real objective is to expand.' A Taiwanese security official described the mission as an effort to manufacture a false impression of de facto control.

The operation's timing was deliberate. It followed a Trump visit to Beijing during which Xi Jinping had reaffirmed Taiwan as the central fault line in U.S.-China relations, and it coincided with Japan and the Philippines discussing overlapping territorial claims in the same waters — an opening Beijing moved quickly to fill. The civilian character of the MSA vessels is precisely the point: they police, map, and challenge without triggering the alarms a naval exercise would. They create facts on the water that accumulate into precedent.

The near-term concern is Taiwan's energy supply. Nearly all of the island's energy is imported, and analysts warn that Chinese vessels could begin pressuring liquefied natural gas carriers — a slow economic stranglehold that stops short of open conflict. The same incremental logic is playing out at Scarborough Shoal, where a floating structure briefly appeared near the lagoon entrance before being towed inside, echoing how China converted South China Sea reefs into military bases despite Xi's 2015 pledge to the White House. Philippine Defense Secretary Gilbert Teodoro was blunt: 'If they lied before, they can lie now.'

Britain, France, and Germany issued a rare joint statement warning that Chinese actions threaten regional stability and freedom of navigation. The U.S. called the moves 'deeply destabilizing' and sent the Philippines $13 million in surveillance drones. But Stanford's Ray Powell, who has tracked China's gray-zone operations closely, named the deeper fear: not that Beijing will act boldly, but that the world will respond with indifference. 'My fear would be that the response from others would be a shrug,' he said. If that happens, the last slice has been taken.

Over the course of a few weeks in mid-2026, Chinese vessels pushed farther into contested Pacific waters than they had in years. Three ships from China's Maritime Safety Agency—a civilian law enforcement organization—sailed through the Bashi Channel between the Philippines and Taiwan, then proceeded east of the island to conduct what Beijing called mapping and research operations. The move marked the first time these civilian vessels had ventured beyond what strategists call the First Island Chain, the arc of islands stretching from Japan through Taiwan and the Philippines that has long served as a psychological and strategic boundary in the western Pacific.

Analysts describe what happened as the "Bashi Breakout," a carefully calibrated assertion of control over waters where China's legal claim to sovereignty is at best murky and at worst indefensible under international law. Ray Powell, who directs the SeaLight project at Stanford University's Gordian Knot Center for National Security Innovation, told observers that Beijing was essentially declaring jurisdiction over territory on the far side of a line it had previously respected. The move represented something new: the first time China had conducted what it framed as a sovereignty patrol outside the controversial 9-Dash and 10-Dash Lines that define its South China Sea claims—lines that a 2016 international tribunal in The Hague ruled had no legal foundation whatsoever. Through a semi-official social media account, China's state broadcaster announced that its vessels had mapped the seabed east of Taiwan for the first time, framing the waters as "nearshore waters" where Beijing maintains presence and exercises governance. The language mattered. If adopted by official government agencies, such a designation could allow China to treat these waters as sovereign territory, effectively barring foreign vessels without permission.

Taiwan's President Lai Ching-te saw the operation for what it was: an expansion of Beijing's grip. "Their real objective is to expand," he said. A Taiwanese security official characterized the MSA mission as an attempt to create a false impression of de facto jurisdiction over the island. During the recent sailing, Chinese vessels issued radio challenges to commercial ships heading toward Taiwan, a signal of intent. The timing was not accidental. The operation followed a visit to Beijing by U.S. President Donald Trump, during which Xi Jinping had made clear that Taiwan remained the central issue capable of derailing U.S.-China relations. It also came as Japan and the Philippines were discussing overlapping territorial claims in their exclusive economic zones east of Taiwan—a development Beijing apparently viewed as an opening to move quickly and assert its own position.

What makes this approach particularly effective, analysts argue, is that it operates in the gray zone between peace and war. The MSA vessels perform policing roles enforcing environmental and maritime regulations. They are civilian, not military, and therefore seem less immediately threatening than a naval exercise. Yet they accomplish something the People's Liberation Army Navy cannot do as easily: they normalize a Chinese presence, establish precedent, and create facts on the water. Powell warned that the near-term target is likely to establish China as the "constabulary" of the sea approaches to Taiwan. The longer-term risk is more ominous: the actual interdiction of commercial vessels, forcing them into Chinese ports or preventing them from reaching Taiwan altogether. Targeting liquefied natural gas carriers would be particularly potent, given that Taiwan relies on imports for nearly all of its energy needs. "Something to let Taiwan know we can starve you out when it comes to LNG," Powell said, describing a scenario where Beijing could slowly tighten control over Taiwan's energy supply.

The same logic applies to Scarborough Shoal, an uninhabited rock with a lagoon roughly 140 miles west of the Philippines' main island and about 530 miles from China's Hainan province. The shoal sits squarely within the Philippine exclusive economic zone, yet China has maintained an almost constant Coast Guard presence there since 2012. Recently, a small floating structure appeared on satellite imagery near the lagoon entrance, prompting protests from Manila. Later images showed it being towed inside the lagoon. China claimed it was conducting maritime research, then said it had been withdrawn. Philippine Defense Secretary Gilbert Teodoro was skeptical. He pointed to the string of South China Sea islands and atolls that China had transformed into military bases despite Xi Jinping's 2015 pledge to the White House not to do so. "If they lied before, they can lie now," Teodoro told the Financial Times. The U.S. Embassy in Manila responded by announcing a gift of four sea-going drones worth $13 million to help the Philippines monitor gray-zone activities and threats to freedom of navigation.

International concern is mounting. Britain, France, and Germany issued a rare joint statement from their de facto embassies in Taipei, expressing concern that Chinese actions "threaten regional stability and the freedom of navigation and safety of international shipping." A U.S. State Department spokesperson called China's actions "deeply destabilizing." Yet Powell's deepest worry may be the most revealing. He fears not that China will act, but that the world will respond with indifference. "My fear would be that the response from others would be a shrug," he said. And if that happens, he added, the last piece of salami has been sliced. The advantage shifts to Beijing.

Beijing is essentially saying we have jurisdiction over this area on the other side of the First Island Chain. That's pretty significant.

Why does it matter that these are civilian ships rather than military ones?

Model

Because civilian vessels seem less threatening, less like an act of war. They can operate in gray zones where military ships would provoke immediate alarm. A coast guard vessel issuing radio challenges to commercial traffic looks like law enforcement. A navy warship doing the same looks like aggression. But the effect is the same—establishing presence, normalizing control, creating precedent.

Inventor

What's the actual risk to Taiwan if China controls the waters east of the island?

Model

Energy starvation, essentially. Taiwan imports almost all its liquefied natural gas. If China can interdict those carriers, it doesn't need to invade. It can simply squeeze. And the mapping operation gives the PLA Navy better understanding of how to operate submarines and task groups in those waters—military advantage wrapped in civilian research.

Inventor

The article mentions the "salami-slicing" strategy repeatedly. What does that actually mean in practice?

Model

It means taking small steps that individually seem minor, each one below the threshold of kinetic war, but cumulatively they shift the baseline. You map a seabed. You issue a radio challenge. You place a research vessel. Each slice is deniable, each one is technically not an act of war. But together they establish facts on the water and normalize your presence in spaces where you had none before.

Inventor

Why did China move now, specifically?

Model

Opportunity. Japan and the Philippines were discussing overlapping territorial claims east of Taiwan. Beijing saw an opening and moved quickly to assert its own position and delegitimize those talks. They have operations planned well in advance and wait for triggering events like this. When one appears, they execute.

Inventor

What would actually stop this?

Model

Concrete pushback—blocking the vessels, forcing them back, making the cost of expansion higher than the benefit. But Powell's fear is that the world will simply shrug. And if it does, then China has learned it can keep slicing without consequence.
