A joint operation between Cambodian and U.S. anti-drug authorities has exposed a cryptocurrency-based money laundering network operating on behalf of Mexico’s Sinaloa Cartel, underscoring once again, how far the cartel’s financial infrastructure now extends beyond North America and Mexico’s traditional smuggling routes.
What Was Uncovered
Cambodian anti-drug police, working alongside the U.S. Drug Enforcement Administration, raided four locations in the Cambodian capital of Phnom Penh and neighboring Kandal province between August 1 and 5, according to Meas Vyrith, secretary-general of Cambodia’s National Authority for Combating Drugs.
The operation resulted in several arrests and the seizure of assets, drug laboratories, and storage facilities. Authorities confiscated more than 200 kilograms of illegal drugs and over one metric ton of precursor chemicals used to manufacture them.
The U.S. Embassy in Phnom Penh confirmed the collaboration in a statement, saying that “collaborative efforts involving Drug Enforcement Administration offices in Phnom Penh and New Jersey successfully uncovered a local network laundering cryptocurrency on behalf of the Sinaloa Cartel.”
Meas Vyrith also disclosed that U.S. officials had separately seized approximately $7 million in cryptocurrency linked to the cartel in an earlier law enforcement action — a seizure that took place in New Jersey, not in Cambodia itself.
Suspects connected to that New Jersey case are now being sought in Cambodia, illustrating how the investigation spans directly across both countries rather than representing two unconnected operations.
A Cartel With an Expanding Financial Footprint
The Sinaloa Cartel, once led by imprisoned kingpin Joaquín “El Chapo” Guzmán, has long been known for smuggling cocaine, fentanyl, and methamphetamine into the United States. Washington designated the group as a Foreign Terrorist Organization in February 2025, and the U.S. Treasury Department has pursued a sustained campaign against its financial networks since.
In March 2025, the Treasury’s Office of Foreign Assets Control designated six individuals and seven entities tied to a Sinaloa Cartel money-laundering network, building on a series of earlier actions dating back to 2023.
Separately, in 2024, U.S. federal prosecutors alleged the cartel worked with Chinese underground banking groups operating inside the United States to launder more than $50 million in proceeds from fentanyl, cocaine, and other drug sales — a precedent that closely parallels the structure uncovered in this latest Cambodia-linked network.
Southeast Asia
Cambodian outlet CamboJA News noted that this case echoes findings previously reported by the United Nations Office on Drugs and Crime, which has documented how Chinese and online scam syndicates operating in Cambodia and the wider Southeast Asian region have expanded their cryptocurrency money-laundering operations by forging alliances with South American drug trafficking organizations.
The pattern suggests the Sinaloa network’s presence in Cambodia may not be an isolated arrangement, but rather one node within a broader, already-established set of relationships between Latin American cartels and Southeast Asian financial crime networks.
Fentanyl Remains Central to the Story
The Sinaloa Cartel remains one of the primary sources of the fentanyl blamed for tens of thousands of overdose deaths in the United States annually. The cartel has sourced precursor chemicals, including from China, to manufacture the synthetic opioid within Mexico before smuggling it across the U.S. border — making the precursor chemicals seized in this operation directly relevant to the cartel’s core production pipeline, not simply a tangential drug-trafficking byproduct of the money-laundering investigation.
Cambodian authorities say they are continuing to investigate the full scope of Sinaloa Cartel money-laundering operations within the country, and suspects tied to the New Jersey cryptocurrency seizure remain sought in Cambodia as of this article.
The case adds a genuinely global dimension to the cartel’s financial reach, reinforcing that U.S. enforcement efforts against Sinaloa’s operations now extend well past the U.S.-Mexico border into cryptocurrency networks spanning Southeast Asia — a front that is likely to remain an active area of joint international law enforcement cooperation going forward.
