Jinmen Island, 2026: China's Coast Guard Harasses Fishermen Daily. Taiwan Has No Answer.

The fisherman keeps his eyes on the white hull. It is 0547 hours, half-light, and the China Coast Guard vessel is three hundred metres off his starboard side. He has been fishing these waters for thirty-two years. His father fished them before him. The vessel has been shadowing him for forty minutes.

Chen Wei-ming is fifty-four years old. He owns a twelve-metre trawler registered in Jinmen County, Republic of China—what the rest of the world calls Taiwan. Jinmen Island sits two kilometres from mainland China. On clear days you can see Xiamen's skyscrapers. Chen's fishing grounds lie in waters that both Taipei and Beijing claim. Until eighteen months ago, Chinese coast guard vessels rarely came this close. Now they come every day.

"They don't board us," Chen says, pulling in empty nets. "They don't need to. They just sit there. The fish don't come when the big ships are around. We go home with nothing."

This is grey-zone warfare. No shots fired. No international incident. Just a fisherman who cannot fish, and a government in Taipei that cannot do anything about it without risking the war it is trying to avoid.

What Changed in February 2025

On February 14, 2025, a Chinese speedboat capsized during a pursuit by Taiwan's coast guard near Jinmen. Two fishermen drowned. Beijing called it murder. Taipei called it an accident during routine law enforcement. Within seventy-two hours, the People's Liberation Army Eastern Theater Command announced "regular patrols" in the Taiwan Strait. The China Coast Guard declared it would "strengthen law enforcement" in waters around Jinmen, Matsu, and other ROC-controlled offshore islands.

The patrols have not stopped. Taiwan's Ocean Affairs Council logged 847 Chinese coast guard incursions into waters around the offshore islands between February 2025 and March 2026. That is an average of 2.3 per day. The vessels range from 1,000-tonne cutters to 10,000-tonne "monster ships"—the largest coast guard vessels in the world, equipped with water cannon and 76mm deck guns.

Taiwan's coast guard has forty-seven vessels. Most are under 1,000 tonnes. They are outmatched and outnumbered. When a Chinese cutter sits in waters Taiwan claims, Taipei has three options: ignore it, shadow it with a smaller vessel, or escalate. Escalation means calling in the navy. That means treating a coast guard vessel as a military threat. That means the risk of the first shots in a war neither side officially wants but both are preparing for.

So Taiwan does not escalate. And the fishermen stay home.

The View From Taipei

At Taiwan's Ministry of National Defense, officials speak carefully. "We monitor all PLA activities in the Taiwan Strait," says a senior official who cannot be named under ministry protocol. "We have the capability to respond to any threat to our sovereignty." Asked whether the coast guard incursions constitute such a threat, he pauses. "We assess each situation individually."

That is the language of a government that knows it is being squeezed and has no good options. Taiwan's 2026 defence budget is NT$606.8 billion (US$19.7 billion)—a 7.7 per cent increase from 2025, but still less than 2.5 per cent of GDP. The People's Liberation Army's official 2026 budget is 1.67 trillion yuan (US$231 billion). Unofficial estimates by the Stockholm International Peace Research Institute put actual PLA spending closer to US$470 billion when off-budget items are included.

Taiwan is spending heavily on asymmetric capabilities: anti-ship missiles, mobile air defence, sea mines, coastal defence cruise missiles. The theory is that Taiwan does not need to defeat an invasion—it needs to make invasion so costly that Beijing will not attempt it. But grey-zone operations do not require an invasion. They require patience, resources, and a willingness to tolerate low-level friction indefinitely. China has all three.

What Washington Sold, and What It Cannot Deliver

Between 2022 and 2024, the United States approved US$20 billion in arms sales to Taiwan. The headline systems: F-16V fighters, M1A2T Abrams tanks, HIMARS rocket artillery, Harpoon anti-ship missiles. Delivery timelines stretch to 2029. Some systems have not yet entered production.

None of these systems help Chen Wei-ming. A Harpoon missile cannot sink a coast guard cutter without starting a war. An M1 tank cannot patrol a fishing ground. The weapons Washington is selling are designed for the war everyone fears. They are useless for the conflict that is actually happening.

Taiwan has asked the United States for systems better suited to grey-zone defence: more coast guard cutters, maritime surveillance drones, non-lethal deterrence equipment. The requests have been approved in principle but not prioritised. The US Coast Guard has a four-year backlog on its own vessel orders. Taiwan is waiting.

The Chip Factory That Makes Taiwan Essential

Thirty kilometres south of Jinmen, in Hsinchu Science Park, Taiwan Semiconductor Manufacturing Company operates the most advanced chip fabrication plants in the world. TSMC produces 90 per cent of the world's most advanced semiconductors—the 3-nanometre and 5-nanometre chips that power everything from iPhones to F-35 fighters to Chinese AI data centres.

This is why American officials call Taiwan "the most important place on Earth." It is why Washington has committed—ambiguously but repeatedly—to defend Taiwan if China invades. And it is why Beijing cannot invade: a military assault would destroy the fabrication plants, rendering the conquest economically pointless. Xi Jinping does not want a smoking ruin. He wants TSMC intact, under Chinese control.

But grey-zone operations do not destroy anything. They just make life harder, year by year. Beijing is not trying to take TSMC by force. It is trying to make Taiwan feel isolated, harassed, and abandoned—so that when Beijing eventually offers terms for reunification, Taipei will have no choice but to accept.

The Recruitment Crisis Beijing Does Not Discuss

There is another reason Beijing prefers grey-zone harassment to outright war: it is running out of young men. China's total fertility rate fell to 1.09 in 2023, one of the lowest in the world. The cohort of eighteen-year-old males—the prime conscription age—has been shrinking since 2015. By 2030, it will be 30 per cent smaller than it was in 2015.

The People's Liberation Army has approximately 2 million active-duty personnel. It has not released detailed recruitment data since 2019, but provincial-level reports show that multiple regions failed to meet conscription targets in 2024 and 2025. The problem is not a lack of funding—it is demographics. The one-child policy, enforced from 1980 to 2015, has produced a generation of only children. Parents are reluctant to send their only son to war. The sons themselves, raised in relative prosperity, are even less enthusiastic.

So the coast guard does the work the PLA cannot risk. The grey-zone campaign requires no conscripts, no body bags, no grieving parents on social media. Just professional mariners, drawing salaries, following orders, and slowly making Taiwan's offshore islands economically unviable.

What the Fishermen Know

Back in Jinmen, Chen Wei-ming ties up his boat at 1130 hours. The catch is forty kilograms of mackerel. A good day used to mean three hundred kilograms. He will sell what he has for NT$6,000 (US$195). Fuel cost NT$3,200. He has been fishing for seven hours. His net income is less than minimum wage.

There are 127 registered fishing boats in Jinmen County. In February 2025, before the patrols intensified, an average of 94 boats went out daily. In March 2026, the average is 41. The Jinmen Fishermen's Association has petitioned the central government for compensation. Taipei has offered subsidies. The fishermen say subsidies are not the point.

"This is our water," Chen says, coiling rope on the deck. "My grandfather fished here when it was still the Republic of China. My son wants to fish here when I'm gone. But if the government cannot keep the Chinese boats out, what is the point?" He pauses. "We are not asking Taipei to start a war. We are asking it to defend what it says is ours."

But that is precisely what Taipei cannot do without risking the war it wants to avoid. And so the white-hulled vessels keep coming. The fishermen keep staying home. And Beijing keeps winning without firing a shot.

What Comes Next

Grey-zone warfare works because it operates below the threshold of what Washington or Tokyo will treat as a casus belli. A coast guard cutter is not an invasion fleet. Harassing fishermen is not annexing territory. But sovereignty is not only about maps and treaties. It is about whether a government can protect its people in the places it claims to govern.

Taiwan is losing that test. Not dramatically. Not in a way that will make headlines in Washington or Brussels. Just a few fishing boats at a time, a few hundred metres of contested water at a time, until one day the people of Jinmen wake up and realise that the Republic of China cannot protect them anymore.

Beijing is counting on that day. It is patient. It has time. And every morning, the white-hulled ships return.
