The River That Divides: Vietnam's Fishermen and China's Grey Fleet

Lý Sơn Island, Vietnam — By the time the boats return to the harbor at Sa Kỳ, the sun has been down for three hours. Nguyễn Văn Tùng, 47, has been awake for 26 of the last 30. His face is salt-crusted, his hands blistered from the nets. He brings his wooden-hulled trawler alongside the dock where his wife waits with their youngest daughter, who is nine and does not yet understand why her father sometimes comes home empty-handed from waters his grandfather fished freely.

"They came alongside us at dawn," Tùng says, meaning the grey-hulled vessels that fly no military flag but carry military men. "Four of them, surrounding our boat. They took our catch. They took our nets. They said we were in Chinese waters." He pauses. "We were 120 nautical miles from Đà Nẵng. My father fished those grounds. His father fished those grounds."

This correspondent has spent eight days in Quảng Ngãi Province, along Vietnam's central coast, speaking to fishermen who work the contested waters of the Paracel Islands — called Hoàng Sa by the Vietnamese, Xisha by the Chinese, and lost to Hanoi in a brief naval battle in 1974. Fifty-two years later, the fish still swim there, and the Vietnamese still try to catch them. But the rules of the sea have changed.

What They Face at Sea

The men of Lý Sơn Island, population 22,000, are among the poorest in Vietnam. They are also among the most strategically significant. Their boats — blue-painted, wooden-hulled, averaging 25 meters in length — venture into waters that Beijing claims under its expansive nine-dash line. They do this not for politics but for tuna, mackerel, and squid. The Vietnamese government gives them fuel subsidies and small loans to reinforce their hulls. It does not give them protection.

Trần Thị Hoa, 52, runs a small provisions shop near the harbor. Her husband has not returned from sea for eight months. Not because he is dead — he calls her on a satellite phone every few days — but because he has moved his operations to the Spratly Islands, further south, where the harassment is less frequent. "The Paracels are finished," she says. "The Chinese have won there. Everyone knows it. Nobody says it."

The harassment follows a pattern documented by the Asia Maritime Transparency Initiative. First comes the approach — Chinese Coast Guard cutters or the unmarked grey vessels of the People's Armed Forces Maritime Militia. Then comes the water cannon, or the ramming, or simply the intimidation of a steel-hulled 3,000-ton vessel bearing down on a wooden boat one-tenth its size. Equipment is confiscated. Catches are seized. Sometimes the boats are sunk.

The Official Version

In Hanoi, the language is careful. The Ministry of Foreign Affairs issues statements that "strongly protest" Chinese actions and "demand" respect for Vietnamese sovereignty. These statements are filed, archived, and forgotten. No Vietnamese naval vessel has confronted a Chinese Coast Guard cutter in the Paracels since 2014. No diplomatic rupture has occurred. No sanctions have been proposed.

Vietnam's calculus is not cowardice — it is arithmetic. China is Vietnam's largest trading partner, with bilateral trade exceeding $171 billion in 2025 according to Vietnam Customs. Chinese investment flows into Vietnamese manufacturing zones. Chinese tourists fill Vietnamese beaches. The Communist Party of Vietnam and the Chinese Communist Party maintain party-to-party relations that run deeper than state diplomacy. What happens to fishermen in wooden boats does not reshape this equation.

Lê Hồng Hiệp, senior fellow at the ISEAS-Yusof Ishak Institute in Singapore, puts it plainly: "Hanoi is playing a long game. They believe that maintaining good relations with Beijing, while quietly strengthening ties with Washington and other partners, will eventually shift the balance. But 'eventually' is not a timeline that helps a fisherman whose boat was rammed this morning."

What the Data Shows

The numbers tell a story of attrition. According to the Quảng Ngãi Provincial People's Committee, the number of registered fishing vessels operating in the Paracel grounds has declined from 2,340 in 2018 to 1,420 in 2025. The provincial government does not publish reasons, but the fishermen know. Some have sold their boats. Some have moved south. Some have simply stopped going to sea.

The economic toll is measured in more than vessels. A 2025 study by the Vietnam Institute of Fisheries Economics and Planning found that fishermen from the three central coast provinces — Quảng Ngãi, Quảng Nam, and Bình Định — reported average annual incomes 34 percent lower than their counterparts in southern provinces who fish less contested waters. The study did not attribute the disparity to Chinese interference. It did not need to.

What Nobody Is Saying

There is a conversation happening in Vietnamese policy circles that does not appear in official statements. It concerns the Philippines, and what Manila's more confrontational approach has achieved. Since 2023, the Philippines under President Ferdinand Marcos Jr. has pursued a strategy of transparency — publishing videos of Chinese Coast Guard water cannons, inviting journalists onto resupply missions, building international coalitions of condemnation.

The results are mixed. The Philippines has secured stronger security commitments from the United States, Japan, and Australia. It has won the public relations war. But Chinese vessels still patrol Scarborough Shoal. The Sierra Madre outpost at Second Thomas Shoal still requires dangerous resupply missions. No territory has been recovered.

"The Vietnamese look at the Philippines and see noise without results," says Collin Koh, research fellow at the S. Rajaratnam School of International Studies in Singapore. "They believe their quiet approach preserves more options. Whether that is wisdom or denial depends on your timeframe."

Back in Sa Kỳ harbor, Nguyễn Văn Tùng does not speak of strategy. He speaks of debt. The boat that was stripped of its nets last week carries a loan he will be paying for another four years. The catch that was seized would have covered three months of his daughter's school fees. "The government tells us we are defending the nation's waters," he says. "But the nation does not defend us."

What Comes Next

The trajectory is visible if you know where to look. Each year, fewer boats venture north. Each year, the grey fleet extends its patrols further south. The process is not dramatic — there will be no moment of capitulation, no signing ceremony, no flag lowered. There will simply be a day, perhaps ten years from now, perhaps twenty, when the last Vietnamese fisherman stops trying to reach the Paracels. And on that day, the Chinese claim will become the Chinese reality, not by treaty or war, but by the slow accretion of unanswered pressure.

Vietnam is not alone in this predicament. The Philippines faces the same calculus at Second Thomas Shoal. Malaysia faces it at Luconia Shoals. Indonesia faces it at North Natuna. The entire architecture of Southeast Asian maritime sovereignty is being tested by a simple question: What happens when one party is willing to absorb more pain than the other?

On Lý Sơn Island, the temple to the Hoàng Sa naval soldiers still stands. Every year, in a ceremony dating to the 18th century, islanders honor the men who died defending these waters under the Nguyễn lords. The ceremony will continue. The fishing will continue, for now. But the sea belongs to whoever can hold it, and on that measure, the contest is already decided.

Tùng's daughter stands at the dock, watching her father unload what little remains in his hold. She asks when he will take her fishing, the way his father took him. He does not answer. Some inheritances are better left unclaimed.
