Captain Liu remembers the exact morning when everything changed. He was hauling in his nets near what his grandfather had always called “Sleeping Turtle Reef” when he spotted something impossible on the horizon. Where there should have been nothing but endless blue water, a mountain of sand was rising from the sea like a slow-motion volcano.
That was twelve years ago. Today, Liu steers his fishing boat past a fully operational military base complete with radar towers and concrete runways. The reef his family had used as a navigation landmark for three generations is now buried under millions of tonnes of sand and steel.
“My son asks me to show him where I learned to fish as a boy,” Liu says, squinting at coordinates on his GPS that no longer match the landscape. “But that place doesn’t exist anymore.”
How China Built Islands from Nothing
What sounds like the plot of a science fiction movie has become one of the most dramatic examples of human engineering in modern history. China’s artificial islands represent the largest land reclamation project ever undertaken in disputed waters, transforming underwater reefs into strategic military outposts.

The process itself is surprisingly straightforward, even if the scale is mind-boggling. Massive dredging ships called “sand tigers” vacuum up sediment from the ocean floor, then pump it through enormous pipes onto shallow reefs and shoals. Layer by layer, what was once three feet underwater becomes dry land rising 15 feet above sea level.
Dr. Sarah Chen, a maritime engineer who has studied the project extensively, explains the technical achievement: “They’re essentially moving entire underwater mountains grain by grain. The logistics alone require a level of coordination and resources that only a few countries could manage.”
The timeline has been relentless. Between 2013 and 2016 alone, China added over 3,000 hectares of new land to the South China Sea. That’s roughly equivalent to adding 4,200 football fields worth of territory where none existed before.
The Scale of Sand: Breaking Down the Numbers
The sheer volume of material moved defies easy comprehension. Here’s how China’s artificial island project breaks down:
| Island Location | Area Created | Key Features |
|---|---|---|
| Fiery Cross Reef | 274 hectares | 3,000m airstrip, port facilities |
| Subi Reef | 274 hectares | Military airfield, naval base |
| Mischief Reef | 558 hectares | Largest artificial island, full military complex |
| Johnson South Reef | 109 hectares | Helicopter pad, communications equipment |
| Cuarteron Reef | 23 hectares | Small military outpost |
The engineering challenges went far beyond simply dumping sand. Each island required:
- Precise mapping of underwater topography
- Massive sea walls to prevent erosion
- Fresh water systems and power generation
- Specialized concrete that can withstand tropical storms
- Deep-water ports carved from solid coral
Environmental scientist Dr. Michael Rodriguez has monitored the project since its early days: “What we’re seeing is unprecedented in terms of speed and scale. They’ve essentially moved the equivalent of a small mountain range into the ocean.”
Who Feels the Impact
The creation of these artificial islands hasn’t happened in a vacuum. The ripple effects touch millions of lives across Southeast Asia, from fishing communities to international shipping lanes.
Filipino fishermen like Captain Liu represent the most immediate impact. Traditional fishing grounds that families had used for generations suddenly became off-limits military zones. The coral ecosystems that supported marine life were buried under millions of tonnes of sand and concrete.
Regional tensions have escalated dramatically. Vietnam, Philippines, Malaysia, and other nations with competing claims in the South China Sea now face a dramatically altered strategic landscape. What were once disputed but uninhabitable reefs are now permanent military installations with radar coverage extending hundreds of miles.
Commercial shipping feels the effect too. The South China Sea carries about $3.4 trillion worth of trade annually, and these new islands sit directly along some of the world’s busiest shipping routes.
Admiral James Patterson, a retired naval strategist, puts it bluntly: “These aren’t just islands. They’re unsinkable aircraft carriers positioned at one of the world’s most critical chokepoints.”
The environmental cost remains largely hidden beneath the waves. Marine biologists estimate that the dredging and land reclamation destroyed approximately 11,000 hectares of coral reef ecosystem. That’s habitat loss equivalent to wiping out an area larger than San Francisco.
What Comes Next
The island-building phase may have slowed, but the militarization continues. Satellite images show ongoing construction of advanced radar systems, missile batteries, and aircraft hangars. What began as simple land reclamation has evolved into a comprehensive strategy for controlling one of the world’s most contested waterways.
For neighboring countries, the question isn’t whether China will continue expanding these facilities, but how far they’re willing to push their territorial claims. Each new radar installation and missile battery represents a permanent shift in the regional balance of power.
The precedent is equally concerning for international law. If building artificial islands can create legitimate territorial claims, every nation with dredging equipment suddenly has a tool for redrawing ocean boundaries.
Dr. Chen believes the project’s long-term significance extends beyond regional politics: “We’re witnessing the birth of a new form of territory creation. This technology could reshape coastlines and ocean boundaries worldwide.”
FAQs
How long did it take China to build these artificial islands?
The major construction phase lasted from 2013 to 2016, though smaller projects and militarization continue today.
Are these islands legally considered Chinese territory?
This remains highly disputed. International law generally doesn’t recognize artificial islands as creating territorial claims over natural features.
How much did the island-building project cost?
Exact costs are classified, but estimates range from $10-20 billion for the construction phase alone.
Can these artificial islands survive major storms?
They’re built to withstand typhoons, but major storms still cause damage requiring ongoing repairs and reinforcement.
What happened to the marine life in these areas?
Extensive coral reef ecosystems were destroyed, with marine biologists estimating massive habitat loss affecting fish populations throughout the region.
Are other countries building artificial islands too?
Several nations have smaller land reclamation projects, but none match the scale or strategic placement of China’s artificial islands.
