Cambodian Tycoon’s Casino Empire Tied to Border-Town Scam and Trafficking Hub

Core Event
Lim Heng Group, the operator of the Royal Hill Resort and Casino in O’S Mach on the Thai-Cambodian frontier, leased three fortified buildings on its grounds to a Chinese national under a March 2024 contract. The lease stipulated a rent of US $200,000 per month for the three structures—far above the US $25,000 monthly rate for a comparable building in Phnom Penh. The agreement described two of the buildings’ dimensions and noted that the third contained 252 rooms. Investigations by Thai security forces and Reuters’ site visits in February–March 2026 found the buildings transformed into mock police stations and bank offices used for large-scale romance-scams, police-impersonation fraud, and the forced labor of trafficked workers.
Background & Context
The O’S Mach border town has experienced a construction boom since 2018, with new facilities clustering around casino complexes owned by politically connected Cambodian elites. Amnesty International and the U.S. State Department’s 2024 human-trafficking report identified Cambodian casino owners as “in direct control” of at least a dozen scam centers. Lim Heng, who holds a royal title equivalent to a duke and donated US $20,000 to the Cambodian military in 2025, has been photographed with senior generals. The Cambodian government has pledged to eradicate scam sites, extradited alleged kingpin Chen Zhi to China, and passed legislation targeting scammers, yet it continues to describe Royal Hill as merely a hotel.
Data & Statistics
- U.S. officials estimated Americans lost US $10 billion to regional fraud in 2024.
- Thai security forces reported the fenced-off compound housed about 3,000 people within a 200-acre “scam park.”
- The lease price of US $200,000 / month was eight times higher than the market rate for comparable space in Phnom Penh.
Official Statements & Responses
Cambodian senior minister Chhay Sinarith said the government is “committed to working with international partners to combat scams” and is investigating alleged fraud around Royal Hill. Information minister Neth Pheaktra rejected Thai claims that the casino was used for drone or sniper attacks, calling the December 2025 Thai bombardment of the site “false.” The Royal Thai Police, led by Gen. Thatchai Pitaneelaboot, asserted that “Chinese gangsters perpetrated scams at the Royal Hill site.” The U.S. State Department’s 2024 trafficking report warned that elite-owned properties enable large-scale scam operations.
Criticism & Opposition
Human-rights advocates, including the Cambodian Human Rights Action Coalition and attorney Piseth Duch, note that landlords can be prosecuted if they knowingly allow criminal use of their property. Amnesty International’s investigation linked casino owners to direct control of multiple scam centers. Critics highlight Lim Heng’s political connections and the lack of a transparent response to the lease documents and allegations.
On-the-Ground Reports
Former worker Pornpen Aimhun recounted being recruited in 2022 via a Facebook job ad, then forced to conduct police-impersonation scams under armed guard. Thai investigators described the interior as “dormitories and office spaces, with sixth-floor rooms staged to resemble foreign bank branches and police stations.” A Thai national convicted for low-level scamming at the site received a five-year prison sentence.
Conflicting Reports & Gaps
Reuters found no direct evidence that Lim Heng Group managed the fraudulent activities, and the company has not responded to inquiries. The September 2024 legal complaint Lim Heng filed against two publishers over reporting of foreign detainees was settled without public clarification, leaving the status of the case unknown. Thai and Cambodian officials dispute the purpose of the December 2025 bombing—Thailand cites security threats, while Cambodia calls it an attack on civilian infrastructure.
Verbatim Quotes
- “Scam centers require physical infrastructure, access to land, and a degree of protection to operate at scale,” — Sophal Ear, professor, Arizona State University
- “A spokesperson for Facebook’s parent company, Meta, said the platform has designed warning messages that appear when users search for keywords that may be associated with fraudulent job posts.” — Spokesperson, Meta
- “She was instead made to participate in a police-impersonation scheme before she escaped.” — Pornpen Aimhun, former trafficked worker
- “Chhay Sinarith, a senior Cambodian minister tasked with combating online fraud, said in response to Reuters’ questions that the government is committed to working with international partners to combat scams.” — Chhay Sinarith, senior Cambodian minister
What’s Next
Cambodian prosecutors retain the authority to charge landlords who knowingly permit criminal use of their properties, and Thai authorities continue to hold portions of the compound. Ongoing investigations by both governments and international partners will determine whether Lim Heng Group faces legal action.
