The UK government has stepped up efforts to tackle crypto-enabled crime by sanctioning Xinbi, a Chinese-language cryptocurrency marketplace, along with a Cambodia-based scam compound tied to trafficking operations.
The measures, announced on March 26 by the Foreign, Commonwealth & Development Office and the Home Office, mark the first time any country has imposed sanctions on the platform.
Officials say the action targets a financial network that supported large-scale fraud, laundering, and exploitation across Southeast Asia, while also freezing UK-based assets linked to the group ahead of the Illicit Finance Summit in June.
Xinbi’s role in crypto crime networks
Data from Chainalysis shows Xinbi processed more than $19.9 billion in transactions between 2021 and 2025.
Authorities say the platform enabled money laundering, unlicensed over-the-counter crypto trading, and the sale of stolen personal data.
Investigators also linked Xinbi to communications infrastructure used in scam operations, including satellite internet equipment that helped target victims.
The platform operated within a wider Telegram-based criminal ecosystem, alongside Haowang Guarantee, described as the largest darknet market recorded.
These networks combined financial services with operational tools, allowing fraud groups to scale their activity while reducing exposure to enforcement.
Cambodia’s compound and trafficking links
The sanctions extend to Legend Innovation Co., which operates Cambodia’s “#8 Park” compound.
Officials say the site is a major scam centre believed to hold up to 20,000 trafficked workers.
The UK designated its director, Eang Soklim, for links to the operation.
Authorities also connected the network to the Prince Group financial system, which had already been sanctioned by the UK and the US last year.
That earlier move led to asset freezes and seizures exceeding £1 billion, highlighting a broader push to dismantle the financial backers behind organised fraud rather than focusing only on individuals.
London assets frozen under new sanctions
Several London properties linked to the network will be frozen under the latest measures.
These add to previously seized UK assets, including a £100 million office building, two multi-million-pound mansions, and a helicopter.
Officials say the restrictions are designed to cut off access to financial channels used to sustain scam operations.
Stephen Doughty said the measures aim to protect British citizens from fraud while addressing human rights abuses tied to scam centres.
The sanctions took immediate effect on March 26, according to The Block.
Global pressure on crypto trafficking finance
The action comes as global scrutiny of crypto’s role in trafficking and fraud intensifies.
A February 2026 report from Chainalysis found crypto flows to suspected trafficking services rose 85% in 2025, with networks relying heavily on stablecoins and Telegram-based systems across Southeast Asia.
Law enforcement activity has increased alongside these trends.
Just days before the Xinbi sanctions, the Federal Bureau of Investigation and Thai police froze $580 million in crypto linked to organised scam groups targeting US victims.
UK officials said the Xinbi case reflects a broader strategy focused on disrupting the infrastructure that enables financial crime.
Authorities plan to use the findings to support discussions at the Illicit Finance Summit in June, where international coordination on tracking and blocking illicit crypto flows is expected to take centre stage.
