The U.S. Office of Foreign Assets Control (OFAC) sanctioned Cambodian Senator Kok An and 28 associated individuals and companies today, accusing his network of running large-scale cryptocurrency investment fraud compounds across Cambodia. The designations were made under Executive Order 13694. The action, coordinated with the Department of Justice's Scam Center Strike Force, also resulted in the seizure of 503 fraudulent websites used to deceive victims and an unnamed messaging application used to recruit trafficked workers. American victims lost more than $10 billion to Southeast Asian scam operations in 2024, a 66 percent increase from the previous year, according to Treasury figures cited in the designation.

The Business Behind the Fraud

Kok An's primary vehicle is Crown Resorts, a hospitality company operating casino complexes in three Cambodian border cities: Poipet on the Thai border, Sihanoukville on the coast, and Bavet on the Vietnamese border. These locations are not incidental. Border towns with limited regulatory oversight became hubs for online fraud infrastructure during the COVID-19 period, when Cambodia's tourism economy collapsed and criminal networks moved in. OFAC also designated Heng Feng Cambodia Bank plc, media company K99 Culture and Media Co Ltd, construction firm Anco Brothers Co Ltd, and Bolai (whose full legal name is Brilliancy Sihanoukville Investment and Development Co) as part of the network.

Key individuals named include Rithy Raksmei of K99 Group, casino operators Aik Paung and Sai Aung Linn, and Luo Hong, the founder of Bolai. Victims were transferred to Luo Hong's operation, with at least $1.3 million in documented victim funds flowing through that entity alone.

Pig-butchering is a form of fraud in which victims are cultivated through fabricated romantic or personal relationships and then persuaded to transfer funds into fraudulent cryptocurrency investment platforms. The compounds operated within Kok An's network served as physical infrastructure for this model across Cambodia's border regions.

Treasury Secretary Scott Bessent said in the department's release: "Eliminating fraud is a top priority... Treasury will continue to target fraudsters and scam centers."

The U.S. also offered a $10 million reward for information leading to recovery of proceeds tied to associated operator Tai Chang, and a $4 million reward for fugitive Daren Li. Neither individual's nationality nor precise role within the network was confirmed in the materials accompanying the designations.

The On-Chain Footprint

The Scam Center Strike Force was formed in November 2025, combining the FBI, Secret Service, DOJ Criminal Division, and U.S. Attorney's Office for the District of Columbia, and operating in coordination with OFAC, the State Department, and the Commerce Department. The Strike Force has now recovered more than $637 million in cryptocurrency since its launch.

That figure sits within a far larger landscape of illicit flows. Chainalysis estimates global crypto scam and fraud losses hit a record $17 billion in 2025, with impersonation scams alone growing more than 1,400 percent year over year. Chinese organized crime networks alone moved $16.1 billion through crypto in 2025, much of it via Tether (USDT), the dominant stablecoin used in Southeast Asian fraud laundering. Blockchain analytics firms including Chainalysis, TRM Labs, and Elliptic typically update their sanctions screening databases to flag wallet addresses tied to newly designated networks; those updates trigger automatic blocks on DeFi protocols and crypto bridges that rely on those tools.

This action follows an enforcement operation in October 2025, when a coordinated U.S. and U.K. action sanctioned 146 individuals in the Prince Group transnational criminal organization led by Cambodian national Chen Zhi. That operation resulted in the seizure of approximately 127,271 Bitcoin, worth roughly $15 billion at the time, the largest cryptocurrency forfeiture in U.S. history. OFAC separately identified an additional $1.8 billion in Bitcoin wallets linked to the Prince Group network beyond the DOJ seizure figure.

What This Means Outside the United States

The fraud compounds are not only a financial story. Between 100,000 and 150,000 people have been trafficked into Cambodian scam operations since this model emerged during COVID-19, per estimates from the UN Office on Drugs and Crime and Amnesty International. In 2025, Cambodia reported more than 3,000 people freed from these compounds.

Victims and forced laborers have arrived from India, Bangladesh, Nigeria, Sierra Leone, Liberia, Uganda, Kenya, Brazil, Indonesia, Myanmar, the Philippines, and Madagascar.

For crypto users and developers across South Asia and Africa, the practical risks are immediate. Exchanges and fintech platforms with exposure to Heng Feng Cambodia Bank's correspondent banking network should identify and assess those relationships. U.S. persons and entities face primary legal obligations under OFAC rules; non-U.S. entities with any U.S. users or U.S.-dollar touchpoints are subject to secondary sanctions exposure. The 503 seized domains represent sites that looked like legitimate crypto investment platforms. Users who interacted with them should report to the FBI's Internet Crime Complaint Center at ic3.gov. South Asian and African platforms that rely on USDT for remittances or savings products, a common use case in Nigeria, Kenya, Ghana, India, and Bangladesh, should run their active wallet lists against updated OFAC sanctions data. Regional fintech firms with Asia-Pacific exposure should also review their connections to the Huione Group payment network, which processed more than $100 billion in Tether over 18 months and is widely used across Southeast Asia, as that network presents significant AML risk for any platform operating in the region.

Thailand had already moved against Kok An before today's U.S. action. Thai authorities raided 19 properties linked to him in mid-2025, seizing $33.8 million in assets, and later raided seven more properties connected to him and his family. Thailand has also requested an Interpol Red Notice for his detention. Cambodia's official posture toward these allegations has been defensive: Cambodian Senate President Hun Sen responded by saying, "I urge Thai politicians to stop blaming Cambodia without evidence, while turning a blind eye to their own country."

Cambodia's National Assembly passed the country's first comprehensive anti-scam law, the Law on Anti-Technology Fraud, on April 3, 2026, just three weeks before today's designation. All 112 members voted in favor. Analysts have attributed the unanimous vote to sustained international pressure following the Prince Group designations.

What Comes Next

The combination of U.S. sanctions, criminal charges against operators in both Myanmar and Cambodia, domain seizures, and a new Cambodian domestic law creates a convergence of pressure that did not exist a year ago.

Whether that pressure is enough to dismantle the remaining compound infrastructure depends partly on Phnom Penh's enforcement follow-through on its new legislation, and partly on whether international financial institutions accelerate their de-risking of Cambodian correspondent banking relationships. Both remain open questions for analysts tracking the region.

The Strike Force's public reward offers suggest that key financial figures remain at large, and further designations remain possible.
