UK sanctions Xinbi to cut off illicit crypto marketplace

The British government announced on March 26 2026 that it is sanctioning Xinbi, one of the region’s largest illicit cryptocurrency marketplaces, in a bid to choke the financial lifelines of scam centres across Southeast Asia [1]. The move also targets operators of the massive “#8 Park” compound in Cambodia, which is believed to house up to 20,000 trafficked workers.

Key takeaways

• The UK is the first country to sanction Xinbi, a crypto escrow service accused of facilitating $19.7‑$19.9 billion in illicit transactions [1][2].
• Xinbi is alleged to sell stolen personal data and provide satellite internet equipment to scam compounds such as #8 Park [1][3].
• Sanctions also include Legend Innovation Co., its director Eang Soklim, and other entities tied to the Prince Group network [1][2].
• The UK government says the measures will freeze London properties linked to the sanctioned parties and isolate Xinbi from the legitimate crypto ecosystem [1][3].
• Crypto‑analysis firms like Elliptic and Chainalysis provided intelligence that helped shape the sanctions [1][2].

Targeting the crypto infrastructure behind Southeast Asian scam compounds

The sanctions focus on Xinbi’s role as a peer‑to‑peer guarantee or escrow platform that enables fraudsters to conduct “trusted” cryptocurrency trades without direct risk [2]. According to the Foreign, Commonwealth and Development Office, Xinbi’s services include money‑laundering, unlicensed over‑the‑counter crypto trades, the sale of stolen data, and the supply of equipment used to contact victims [3]. Blockchain analytics from Chainalysis show the platform facilitated more than $19.9 billion in crypto flows between 2021 and 2025, with many funds linked to “pig‑butchering” romance scams [2].

Elliptic, a UK‑based crypto‑analysis firm, assisted the government’s investigation and previously described Xinbi as “the second‑largest illicit online marketplace ever” [1]. Its research identified crypto‑asset addresses used by merchants inside #8 Park, including everyday vendors that accepted USDT payments from workers [1]. After Elliptic’s February 2026 report, intelligence indicated the Xinbi‑linked compound was ordered to evacuate, with on‑chain data showing a sharp drop in merchant payments by mid‑February [1].

Broader crackdown and international coordination

The Xinbi sanctions follow earlier coordinated actions by the UK and the United States that designated 146 individuals and entities linked to the Prince Group in October 2025, leading to the arrest and extradition of its chairman Chen Zhi in January 2026 [1][3]. Cambodia’s government responded with its largest ever crackdown, raiding an estimated 2,500 sites and freeing tens of thousands of foreign nationals [1]. British officials, including Minister of State Stephen Doughty and Fraud Minister Lord Hanson, said the new measures send a clear message that the UK will not tolerate scams that target its citizens or exploit trafficked workers [1][3].
