Fraud Centers Behind Cambodia's Rapid Development
Twenty-nine Japanese nationals detained in May in Poipet, a Cambodian city on the border with Thailand, became part of an international investigation into fraud operations hidden inside sprawling compounds. They were transferred to Phnom Penh, where Japanese law enforcement officials traveled to investigate their links to scams targeting people in Japan.

The detentions exposed one part of a much larger network. Across Cambodia, transnational crime syndicates, particularly groups with roots in China, have established compounds that can serve as both workplaces and prisons. Thousands of foreign nationals, including Japanese, South Koreans, Australians and people from across Southeast Asia, have been drawn into these operations through recruitment, deception or coercion.
Cambodian authorities say around 24,000 people involved in online fraud and human trafficking have been uncovered over the past three years. They also say nearly 5,000 people from more than 20 countries have been rescued. Human rights organizations argue that the problem extends far beyond those figures.
Inside the compounds, workers contact potential victims around the world, posing as police officers, prosecutors, bank employees or romantic partners. Many workers are themselves victims of trafficking, confined behind guarded entrances and forced to help steal money from others.
As of July 12, 2025, Cambodia's government has pledged action and pointed to raids and rescues. Allegations of corruption, official interference and continued operations at exposed sites have placed the effectiveness of that response under growing scrutiny.
Compounds Built to Keep People Inside
Scam compounds are large, often fortified complexes housing hundreds or even thousands of people engaged in online fraud, telephone scams and related crimes. Many are located in border regions or special economic zones, where oversight is limited and law enforcement may be overwhelmed or complicit.
Supermarkets, nightclubs, karaoke rooms and other facilities allow residents to remain inside for long periods. Some developments also have casinos under construction. The appearance of a complete commercial neighborhood can conceal a tightly controlled environment in which ordinary workers are rarely allowed to leave.
Business partners and selected outsiders may enter or leave, while residents face restrictions on their movements. Providing daily necessities inside the walls gives operators another way to maintain control over the people working there.
Recruiters often advertise legitimate jobs in information technology, customer service or casinos. Some recruits are attracted by promises of high earnings abroad. After arrival, many discover that the work involves fraud and that their passports have been confiscated.
The range of nationalities inside the compounds reflects recruitment networks that stretch well beyond Cambodia. Southeast Asians, South Koreans, Australians and Japanese nationals have all been reported among those working in these centers.
A Changing Landscape in Prey Veng
Prey Veng province offers a close view of how quickly these developments can transform an area. A driver who regularly transported Chinese investors to one compound described a place resembling a Chinese town, with Chinese restaurants, a hospital and businesses accepting Chinese yuan.
A self-employed man delivering construction materials to the site described the speed of the change:
This area used to be covered in rubber plantations. It's developed rapidly over the past year.
The delivery worker said the influx of Chinese investment had transformed the region while creating unease among local people who suspected the real purpose of the businesses being established.
A driver familiar with the Prey Veng compound gave a blunt assessment of its reputation:
Everyone knows that this is a fraud base.
A senior local government official in Prey Veng said all the major development projects in the area were suspected of being used as scam bases. According to the official, attempts to investigate had been blocked by higher authorities.
These accounts describe development proceeding alongside local suspicion and limited room for intervention. Restaurants, hospitals and new construction make the sites look like busy commercial districts, while allegations about confinement and fraud concern what happens behind their controlled entrances.
How the Fraud Is Organized
Workers inside the compounds are organized into call centers and given scripts and lists of people to contact. The scams depend on social engineering, which means manipulating someone's trust, fear or emotions to persuade them to hand over money.
In one case uncovered by Japanese police, a suspect impersonated police officers or prosecutors to persuade Japanese victims to transfer funds. A supposed official can create pressure by making a target believe that an urgent payment is necessary.
Other operations use people posing as bank employees or romantic interests. Although the identities change, the central method remains personal persuasion: a worker builds trust or creates anxiety, then seeks a transfer of money.
Different teams handle different stages, from the first contact with a victim to money laundering. Money laundering means moving or disguising criminal proceeds so they appear to come from legitimate activity. This division of work allows a compound to operate as an organized fraud business.
Some compounds employ thousands of people and generate millions of dollars in illicit profits each month. Their international reach connects the people making calls in Cambodia, victims losing money abroad, recruiters moving workers across borders and networks handling the proceeds.
Japanese Investigations Cross Borders
Fukuoka Prefecture police uncovered several recruiters for special fraud operations linked to Cambodia in April and May. Japanese suspects were found working in compounds, including some who had been attracted by promises of highly paid employment overseas.
The detention of 29 Japanese nationals in Poipet in May brought further attention to those connections. Poipet, known for casinos and rapid development, sits beside Thailand and forms part of the border economy in which these operations have expanded.
After the detainees were transferred to Phnom Penh, Japanese officials traveled there to investigate their possible connections to fraud cases at home. Similar arrests have involved compounds elsewhere in Cambodia and in neighboring Myanmar and Laos.
The developments described through July 12 followed this sequence:
- April and May: Fukuoka Prefecture police uncovered several recruiters linked to special fraud operations in Cambodia.
- May: Cambodian authorities detained 29 Japanese nationals in Poipet, later transferring them to Phnom Penh.
- After the transfer: Japanese law enforcement officials traveled to Phnom Penh to investigate links to fraud in Japan.
- June 26: Amnesty International released a report criticizing Cambodia's handling of scam compounds and alleging official collaboration or coordination with their operators.
The legal outcomes for the 29 Japanese detainees were not specified. Their cases sit within a wider international effort involving agencies from Japan, South Korea, Australia and other countries investigating the recruitment and exploitation of their citizens.
Why Crime Networks Have Expanded in Cambodia
Chinese organized crime groups are widely believed to direct many of Cambodia's scam compounds. They have used weak regulation, limited law enforcement capacity and the country's location to establish networks of fraud bases.
Cambodia borders Vietnam, Thailand and Laos, giving criminal networks several routes for moving people and conducting business across national boundaries. Special economic zones offer tax advantages and limited oversight, creating conditions that operators can exploit.
Casinos, hotels and other enterprises can provide fronts for criminal activity. Casinos are legal in Cambodia but banned in neighboring countries, and their presence offers opportunities to disguise illicit money movements within apparently legitimate business activity.
Chinese investment has risen rapidly, particularly near Cambodia's borders with Vietnam and Thailand. It has brought economic benefits, including tens of thousands of jobs, while also prompting concerns about corruption, money laundering and a loss of local control.
Rapid infrastructure development, often funded by Chinese investment, has helped create opportunities to build large, fortified compounds with little interference. Criminal operations can be concealed within projects presented as ordinary commercial investment.
Officials at different levels have been accused of overlooking illegal activity in exchange for bribes or other benefits. Local officials who try to intervene may be ignored or overruled by higher authorities, while the economic benefits of investment create incentives to leave projects undisturbed.
Workers Facing Trafficking and Forced Labor
Many people working in scam compounds arrive after accepting false job offers or being sold by traffickers. Once inside, they may face harsh working conditions, physical abuse and threats of violence.
Confiscated passports and tightly restricted movement make leaving difficult. For many, escape is impossible without help from outside the compound. The same person forced to deceive a fraud victim abroad may be living under threats and confinement in Cambodia.
Cambodia's government says it has uncovered around 24,000 people involved in online fraud and human trafficking over three years and rescued nearly 5,000 people from more than 20 countries. The first figure describes people uncovered in connection with those activities; the second describes people rescued.
Human rights organizations say the scale is much greater. Their concerns include people who remain trapped, the treatment of those who get out and the ability of operators to keep functioning after raids.
The human cost therefore reaches two groups at once: people whose money is stolen and people forced to carry out the theft. Investigations into the fraud have to address how workers were recruited, whether they could leave and what threats they faced inside.
Amnesty Alleges Official Collaboration
Amnesty International, the human rights organization, released a report on June 26 accusing Cambodian authorities of what it described as "collaboration or coordination" with Chinese organizations operating scam bases.
The organization alleged that many compounds continued operating after being exposed. It also described some official interventions as "for show," challenging government claims that publicized actions demonstrated an effective response.
Amnesty International's statement focused on the continuing exploitation of workers and the lack of accountability for those responsible:
Despite publicized raids and rescues, the underlying structures of exploitation and impunity remain largely intact, with many victims left without adequate support or justice.
The organization called for greater international cooperation and accountability, alongside stronger protections for victims of trafficking and forced labor. Its concern extended beyond removing people from particular buildings to the criminal networks and official conduct that allowed the operations to continue.
For people leaving the compounds, the report's criticism concerned access to support and justice after rescue. For those still confined, continued activity at exposed sites meant that publicity and enforcement announcements had not necessarily ended their exploitation.
Raids, Corruption and International Pressure
Cambodia's government has publicly promised to crack down on scam compounds and human trafficking. It cites recent raids and rescues as evidence of progress against the networks.
Critics argue that those efforts remain insufficient and are weakened by corruption and a lack of political will. Allegations that local investigations have been stopped by higher authorities point to problems within the enforcement process, alongside the practical challenge of reaching people held inside guarded compounds.
Law enforcement agencies from Japan, South Korea, Australia and other countries are working with Cambodian authorities to investigate and prosecute people responsible for recruiting and exploiting their citizens. Cases can involve recruitment in one country, confinement in another and fraud victims elsewhere.
Weak legal frameworks and limited resources make that work difficult. The international structure of the syndicates also spreads responsibility across borders, requiring authorities to connect recruitment, coercion, fraud and the movement of money.
Criminal proceeds can support further money laundering, drug trafficking and corruption. Meanwhile, vulnerable people continue to face the risk of being moved across borders through deceptive recruitment or trafficking networks.
The response described by governments and human rights organizations requires sustained work by law enforcement, civil society, the private sector and national authorities. Its concrete tasks include investigating operators and recruiters, protecting people subjected to forced labor and pursuing the money taken from fraud victims around the world.
