The U.S. Treasury Department announced on Saturday that it had placed Senator Kok An, a prominent Cambodian businessman and long‑time ally of former Prime Minister Hun Sen, on its sanctions list alongside 28 individuals and companies accused of facilitating a large‑scale online fraud enterprise. The designation, issued under the authority of the Office of Foreign Assets Control, freezes any assets the listed parties hold under U.S. jurisdiction and bars American persons from dealing with them.
According to the Treasury’s statement, Kok An leveraged his political connections to shield a network that allegedly defrauded U.S. residents of millions of dollars through cryptocurrency‑related schemes and other investment scams. The sanctions also encompass Kok An’s hospitality firm Crown Resorts, which the United States claims operates properties that have been repurposed as scam compounds, and his diversified conglomerate Anco Brothers Co. Ltd., which the agency says provides logistical support, security personnel and licensing for casino operations linked to the fraud.
Treasury Secretary Scott Bessent framed the action as part of a broader effort to eradicate financial crime, noting that the administration will continue to pursue perpetrators of fraud regardless of their political stature or geographic location. The announcement referenced the inter‑agency Scam Centre Strike Force, a task‑force created in late 2023 to combat Southeast Asian cryptocurrency fraud, which also disclosed separate charges against two suspects operating a scam site in Myanmar and attempting to establish a similar hub in Cambodia. The Strike Force reported the seizure of a messaging platform used to recruit victims for human‑trafficking‑linked scams and the shutdown of more than five hundred fraudulent web domains.
The United States has long warned that scams emanating from the region impose a heavy burden on American consumers. A Treasury estimate released in 2024 placed the annual loss to U.S. citizens at roughly $10 billion, a figure that has guided successive administrations to prioritize enforcement actions against overseas fraud rings.
Cambodia has emerged as a focal point for these illicit operations. Multiple investigative reports have documented the involvement of high‑level officials and business magnates in providing safe‑houses, financial services and labor pipelines for scam syndicates that are largely organized by Chinese criminal groups. While Cambodian authorities have repeatedly denied any collusion, the pattern of U.S. sanctions suggests a growing willingness to hold individual actors accountable.
The Treasury’s filing alleges that Crown Resorts owns a portfolio of casinos, resorts and other facilities in border towns such as Poipet, Bavet and the coastal hub of Sihanoukville. These sites, the agency claims, have been transformed into “scam compounds” that generate rental income for Kok An while also receiving ancillary services, including uniformed security supplied by his conglomerate. Anco Brothers is said to hold the operating licenses for the casinos situated on these properties, thereby integrating legitimate gaming revenue with illicit proceeds.
Kok An is not the first Cambodian oligarch to face U.S. sanctions for cyber‑fraud. In October 2025, the Treasury blacklisted more than a hundred entities tied to Prince Holding Group, including its chairman Chen Zhi, a former senior adviser to Prime Minister Hun Manet. Earlier sanctions also targeted Ly Yong Phat, another senator‑businessman, for alleged involvement in forced labor, human‑trafficking and online scams. The pattern illustrates a systematic approach by Washington to isolate individuals who sit at the nexus of politics, finance and illicit activity.
Born in 1954 to an ethnic Chinese family in the border province of Koh Kong, Kok An has built a business empire that spans real estate, finance and utilities. Ministry of Commerce records list at least eleven companies under his control, including the former Anco Brothers website’s claim to be the exclusive distributor for brands such as British American Tobacco, Evian and Budweiser. U.S. diplomatic cables from 2007 described him as a “gambling kingpin,” a label reinforced by his extensive casino holdings across the country.
The Poipet complex, originally launched in 1999 as Crown Resorts, has been singled out by multiple watchdogs as a hub for online fraud. A 2024 Cyber Scam Monitor report called the site “the most prominent and apparently untouchable venue hosting scam operations in Poipet,” noting documented cases of fraud dating back to 2016 and a series of unexplained deaths among workers. Human rights groups have criticized the Cambodian government’s response as insufficient, accusing it of turning a blind eye to the industry that thrives on trafficked labor from across Asia and beyond.
The latest sanctions arrive amid a shifting domestic landscape in Phnom Penh. After years of shielding figures like Chen Zhi, the Cambodian government extradited him to China in January 2026, signaling a willingness to cooperate with external pressure. Since then, authorities have conducted a series of raids on suspected scam sites, and in February passed a law aimed at strengthening the legal framework against online fraud. High‑ranking officials, including a deputy director‑general of immigration and a senior police commissioner, have been arrested on charges of bribery and money laundering linked to scam operations.
Nevertheless, analysts caution that political constraints may limit the depth of accountability. The ruling Cambodian People’s Party continues to rely on a network of business patrons for financial support, and past instances of protective treatment for individuals like Ly Yong Phat suggest that sanctions may not translate into systemic reform.
From a geopolitical perspective, the United States’ intensified focus on Southeast Asian cyber‑crime dovetails with broader strategic competition with China. Beijing has historically maintained close economic ties with Cambodia, investing heavily in infrastructure and tourism projects. By targeting figures who operate at the intersection of illicit finance and political patronage, Washington seeks to curtail a revenue stream that could indirectly bolster Chinese‑aligned actors, while also demonstrating its resolve to protect American consumers.
For global markets, the sanctions underscore the growing risk that political patronage networks in emerging economies pose to financial stability. Investors with exposure to Cambodian hospitality, gaming or real‑estate sectors may need to reassess compliance frameworks and monitor further regulatory actions. The broader lesson for multinational firms operating in the region is the importance of rigorous due‑diligence on counterparties, especially where business interests intersect with politically exposed persons.
As the United States continues to leverage financial tools to disrupt transnational fraud, the Cambodian government faces a delicate balancing act: it must address international concerns and domestic social costs while preserving the patronage structures that underpin its political base. The outcome will shape not only the trajectory of cyber‑crime in the Mekong sub‑region but also the contours of great‑power influence in a strategically vital part of the Indo‑Pacific.
