The numbers are staggering in their scale. According to a 2024 United Nations report, between 100,000 and 150,000 people -- many of them foreign nationals lured by fraudulent job advertisements -- are believed to have been trafficked into Cambodian scam compounds. Amnesty International identified at least 53 active compounds across 16 different areas in the country by mid-2025, concentrated in places like the Bavet special economic zone near the Vietnamese border. The compounds occupy converted casinos, hotels, office buildings, and residential blocks. From the air, they look unremarkable. From inside, workers describe conditions of captivity: confiscated passports, physical abuse, and forced participation in online fraud schemes targeting victims around the world.

The transformation happened fast. Cambodia's 2019 ban on online gambling gutted the revenue streams of criminal networks that had operated through the country's casino industry for years. Then the COVID-19 pandemic collapsed tourism, particularly the flow of Chinese visitors that many establishments depended on. Faced with sudden economic losses, these networks pivoted. From 2021 onward, casinos and hotels across Cambodia were converted into scam-compound operations. The workforce came from trafficking networks that already had deep roots in the country, now repurposed to recruit victims with promises of legitimate employment. Videos filmed inside compounds and leaked online in 2021 -- showing workers subjected to beatings and torture -- brought the first wave of international attention.

The operations run a grim variety of fraud. Among the most common is what investigators call "pig butchering" -- a scheme in which scammers build fake romantic or professional relationships with targets over weeks or months before steering them toward fraudulent cryptocurrency investments. The Global Anti-Scam Organization documented over 1,838 victims from 46 nationalities who lost an average of $169,000 each to such schemes. Across Cambodia, Myanmar, and Laos combined, the cybercriminal labor force exceeds 350,000 people, generating an estimated $50 to $75 billion annually. The victims are on both sides: those defrauded of their savings, and those held captive and forced to carry out the deception. Chinese nationals make up the largest share of trafficked workers, but the nets have widened to include people from across Southeast Asia, Africa, and beyond.

Raids have occurred, arrests have been made, and promises have been issued. In 2024, operations in Bavet led to 450 arrests connected to online gambling and scam activities. Cambodia has made over 1,000 arrests in broader crackdowns on cybercrime. Southeast Asian leaders have pledged cooperation to dismantle the networks. But the compounds persist. Policy analysts describe the scam industry as deeply intertwined with Cambodia's political economy -- an evolution of earlier patronage networks that moved through resource extraction, concession-linked business, and casino development before settling on cyber-fraud as their most profitable incarnation. The networks adapt: when one compound is shuttered, operations migrate to new locations. The infrastructure of exploitation proves easier to relocate than to destroy.

What makes Cambodia's scam-compound crisis distinct is its industrial character. This is not petty fraud run from back rooms. It is a system of forced labor operating at the scale of a national industry, generating revenue that rivals Cambodia's legitimate economy. The trafficked workers -- deceived, detained, and coerced -- occupy a grey zone that complicates international response. Many entered Cambodia voluntarily on the strength of fraudulent job offers, making their status as trafficking victims initially ambiguous to authorities. Those who have been rescued describe the difficulty of returning to normal life, haunted by what they were forced to do and by the knowledge that the compounds they escaped are still operating. The buildings remain visible from the road, and from the air. They look like any other development in a rapidly urbanizing landscape. The difference is what happens inside.
