Pull up any satellite photo of disputed waters in the South China Sea, and you’ll see what looks like hundreds of regular fishing boats. But take a closer look. These vessels aren’t hauling nets for tuna. They’re part of something far more calculated. A maritime militia operates in the gray zone between peace and war, where a fishing fleet can become a tool of territorial expansion without firing a single shot.
- China deploys an estimated 17,000 to 200,000 vessels that function as both commercial fishing operations and paramilitary forces, creating the world’s largest maritime militia.
- Filipino fishermen have been injured, water-cannoned, and blocked from their traditional fishing grounds as China uses these civilian-looking vessels to assert territorial claims in the South China Sea.
- This gray zone strategy operates below the threshold of military conflict, making it difficult for other nations to respond without escalating to full-scale confrontation.
The Little Blue Men Taking Over the South China Sea
Manila calls them “little blue men,” a play on Russia’s “little green men” from Crimea. Civilian fishing boats swarm contested reefs and shoals in coordinated formations that look suspiciously like military maneuvers. Anchoring for weeks or months at strategic locations, they block access to other countries’ vessels and fishermen.
What makes this strategy so effective? Because these aren’t warships, international law treats them differently. Flying civilian flags and operating under commercial fishing licenses, they technically enjoy sovereign immunity as civilian vessels. But Chinese government documents reveal these boats receive subsidies, military-grade communications equipment, and direct orders from the People’s Liberation Army Navy.
Take Scarborough Shoal, where Filipino fishermen have worked for generations. Since 2012, Chinese coast guard vessels backed by these fishing boats have systematically blocked Filipino crews from accessing the area. One 70-year-old retired fisherman recalls earning $705 on three-month trips before the takeover. Now those same waters are off-limits, patrolled by hundreds of vessels that look harmless but act as an occupying force.
How Gray Zone Operations Actually Work
You might wonder how fishing boats can be military assets. Coordination and sheer numbers make it work. When tensions rise at places like Second Thomas Shoal or Sabina Shoal, suddenly 200 or more vessels appear within days. Instead of attacking, they swarm. Anchoring in tight formations, they cut other boats’ anchor lines and create physical barriers that become nearly impossible to pass through.
Just last week, three Filipino fishermen were injured when Chinese coast guard ships fired water cannons at their vessels near Sabina Shoal. Two fishing boats suffered damage from the high-pressure blasts. This happened in waters that fall squarely within the Philippines’ exclusive economic zone, about 150 kilometers from Palawan Island.
This approach forces other countries into an impossible choice. Send military ships to confront civilian fishing boats, and you risk looking like the aggressor on the world stage. Do nothing, and you slowly lose access to your own territorial waters. China has been picking the latter option for years, gradually expanding its control reef by reef.
The Real Cost for Working Fishermen
While politicians debate territorial claims, actual fishermen are getting squeezed. Philip Macapanas, a fisherman from Zambales, used to earn $136 per trip a decade ago. Now he’s lucky to bring home $34. The fish populations have crashed from illegal fishing and habitat damage, and Chinese vessels block access to the best remaining spots.
Reports from fishing communities describe harassment that goes way beyond intimidation. Filipino crews have been forced to march barefoot across sharp coral reefs. Chinese vessels chase them at close range. Some get detained, questioned, or have their equipment confiscated. Far from isolated incidents, these encounters have become routine for anyone trying to fish in disputed waters.
A 2024 study found 77 Chinese-flagged vessels operating illegally in Philippine exclusive economic zones, contributing to a measurable drop in the country’s GDP. About one-third of the Philippines’ fish production comes from the South China Sea, which supports over 300,000 fishermen. When those resources disappear, entire coastal communities collapse into debt and poverty.
What Can Actually Stop This?
Washington has ramped up military aid to the Philippines, including $500 million in foreign military financing. But money doesn’t solve the real issue here: how do you counter civilian vessels acting as military forces without starting a war?
Some military analysts suggest treating these militia vessels as privateers, which are historical pirates with government backing. Under that legal framework, countries could board and seize suspect vessels, forcing China to either claim them as military assets (which would expose their gray zone strategy) or disavow them (which would undermine their effectiveness).
Others point to better surveillance technology. Modern satellite tracking, behavioral analytics, and artificial intelligence can identify which fishing boats are actually engaged in commercial fishing versus which ones are conducting military-style patrols. Fishing boats that consistently anchor near disputed features without deploying nets or showing fishing activity patterns become obvious candidates for enforcement action.
Manila has also tried creating a unified maritime command structure combining its Navy, Coast Guard, and fisheries bureau. On paper, this makes sense, but coordination remains messy when confrontations happen fast and agencies have different chains of command.
Where This Leaves Everyone
China’s fishing fleet strategy represents something new in international conflict. Warfare without war, expansion without invasion, occupation without open military deployment. This approach works precisely because it’s hard to counter with traditional military responses.
For countries like the Philippines, Vietnam, and Malaysia, things keep getting worse. Filipino fishermen can’t access traditional fishing grounds. Coast guards get outnumbered and harassed. International law provides limited tools when the aggressor operates through civilian proxies.
Whether this becomes a model for territorial disputes everywhere remains the bigger question. If one country can successfully grab contested areas using fishing boats and coast guard vessels instead of warships, why wouldn’t others try the same thing? We might be watching the future of geopolitical competition, one where the line between civilian and military blurs so completely that traditional concepts of warfare stop making sense.
