KUALA LUMPUR: Cambodia's arrest and extradition of a powerful tycoon accused of running a vast online scam network marks a rare strike against an industry that has stolen tens of billions of dollars worldwide. US and UK authorities say Chen Zhi led a transnational criminal enterprise that exploited trafficked workers and defrauded victims worldwide.
For victims, the scams often start small: a text offering a part-time job, asking about weekend availability, or simply saying “hello.” On the other end is often a labourer halfway around the world, forced to work 12- to 16-hour days, sending message after message until someone responds.
That human toll is immense. Hundreds of thousands of people are believed to be trapped in forced labour, housed in sprawling compounds across Southeast Asia and compelled to run scams whose sole purpose is to take your money.
Even with a high-profile arrest, dismantling the industry remains extraordinarily difficult. Here's why:
The crackdown in Myanmar
The Myanmar military last October moved into one of the most well-known scam compounds — the massive KK Park, along the border with Thailand — and announced it had shut the operation down. However, work has continued uninterrupted at other scam centres in Myanmar, where people trafficked from around the world still wait to be rescued.
The raid triggered a mass flight of workers. About 1,500 labourers crossed into Thailand, including hundreds from India as well as citizens from China, the Philippines, Vietnam, Ethiopia and Kenya. Thai military officials said troops later demolished several structures within the massive complex.
KK Park was only one of dozens of such centres along the Thai-Myanmar border — and hundreds more scattered across Southeast Asia — underscoring how difficult it is to dismantle an industry that can quickly shift operations when under pressure.
Emerging from casinos and illegal gambling
Scam compounds are often sprawling complexes in rural areas, complete with sleeping quarters, shops and entertainment venues for workers. Developers typically build a single property and lease space inside to multiple companies, allowing numerous operations to run side by side.
Many operate with the protection of local elites. Smaller setups also exist, tucked into a single floor of a legitimate office building or even a rented house in an urban neighbourhood.
The centres trace their roots to casinos — both physical and online — that proliferated across Southeast Asia over the past decade. The United Nations Office on Drugs and Crime counted more than 340 licensed and unlicensed casinos in the region in 2021 alone.
Those casinos, often paired with junket tours, catered to high-rollers from China, where gambling is illegal, and were frequently run by Chinese criminal groups.
When the COVID-19 pandemic and strict travel restrictions cut off customers, some online casinos pivoted. With revenue drying up, operators shifted to a new model: using the same infrastructure and labour to defraud targets around the world through digital scams.
Relying on both trafficked and willing labour
An estimated 120,000 people in Myanmar are being forced to work in online scam operations, along with another 100,000 in Cambodia, according to a 2023 report by the UN Office of the High Commissioner for Human Rights.
Those figures are rough estimates, but investigators say scam centres rely on a mix of trafficked victims and workers who arrive willingly — lured by false promises of relatively high pay and easy office jobs.
Early on, most workers came from China and Chinese-speaking countries. Today, the UN Office on Drugs and Crime says labourers are recruited from at least 56 countries, ranging from Indonesia to Liberia.
For many, the reality is far harsher than advertised. Workers say their passports are often confiscated to prevent them from leaving the compounds. Only senior managers and trusted lieutenants are allowed to move freely. Those who fail to meet targets risk beatings or other physical punishment.
A global scourge
Scammers cast a wide net, targeting victims around the world and increasingly relying on artificial intelligence-powered translation tools to overcome language barriers.
In the Philippines, authorities raided a compound in March 2024 where workers were targeting Chinese nationals with a fake investment scheme. Using scripted messages, scammers posed as senior employees of the state-owned China National Petroleum Corp. and persuaded victims to invest in crude oil futures, according to a script seen by The Associated Press.
Elsewhere, the impact has been just as far-reaching. Last year, about 50 South Koreans were repatriated from Cambodia after being arrested over several months on allegations they worked for online scam operations.
US prosecutors have also targeted the networks behind the schemes. Prosecutors in an indictment against Chen Zhi last year said his organisation had scammed at least 250 Americans out of millions of dollars, including one victim who lost USD 400,000 in cryptocurrency. Americans lost at least USD 10 billion to scams tied to Southeast Asia in 2024 alone, according to the US Treasury Department.
Cambodian authorities said Wednesday that Chen Zhi and two other Chinese citizens were extradited to China on Tuesday. Chen has dual nationality, and his Cambodian citizenship was revoked in December, it said.
The victims
The scams take many forms, ranging from cryptocurrency investment schemes to so-called “task scams,” in which victims are asked to pay to unlock the next assignment. In some cases, small amounts of real money are paid out early on to build trust before losses escalate.
Scammers often manufacture urgency, warning targets they will miss out on an opportunity unless they invest by a specific deadline.
Despite government crackdowns and raids that have freed some workers and shut down individual compounds, activists say the people behind the operations largely remain untouched. New scam centres continue to surface across Southeast Asia and beyond.
A United Nations report last year said scammers have extracted billions of dollars from victims using fake romantic relationships, bogus investment pitches and illegal gambling schemes, with operations reported as far away as Africa and Latin America.
“If we only rescue the victims and don't arrest anybody — especially the Chinese mafia and transnational syndicates — then there will be no point,” said Jay Kritiya, coordinator of the Civil Society Network for Victim Assistance in Human Trafficking.
“They can get more victims. They can scam anytime,” Kritiya said.
