The Treasury Department has exposed a shocking alliance between Chinese money laundering networks and Mexican drug cartels that has enabled billions in fentanyl profits to flow freely across international borders.
Story Highlights
- Treasury sanctioned six individuals and seven entities linked to Sinaloa Cartel money laundering operations in March 2025
- Chinese Money Laundering Networks now facilitate cartel financial operations through sophisticated underground banking systems
- FinCEN issued urgent advisory warning banks about emerging laundering typologies involving Chinese intermediaries
- High-profile fugitive Zhi Dong Zhang allegedly laundered over $150 million for major cartels before escaping Mexican custody
Treasury Targets Cartel Financial Infrastructure
The Office of Foreign Assets Control delivered a decisive blow against the Sinaloa Cartel’s money laundering operations on March 31, 2025, sanctioning six individuals and seven entities facilitating billions in drug proceeds. Treasury Secretary Scott Bessent emphasized the administration’s commitment to dismantling these criminal financial networks that fuel America’s fentanyl crisis. The coordinated action represents the most comprehensive assault on cartel financing under the new administration, targeting both operational leaders and their financial facilitators.
These sanctions freeze all U.S.-based assets and prohibit American individuals and entities from conducting business with designated targets. The Treasury’s aggressive stance demonstrates President Trump’s promise to wage economic warfare against organizations poisoning American communities. Law enforcement agencies including the DEA, FBI, and Homeland Security Investigations provided crucial intelligence supporting these enforcement actions.
Chinese Networks Enable Cartel Operations
FinCEN’s August 28, 2025 advisory revealed the alarming extent of Chinese Money Laundering Networks supporting Mexican cartels through underground banking systems. These networks exploit regulatory gaps in international financial oversight, offering cartels efficient and virtually untraceable money movement services. Director Andrea Gacki warned that “Chinese money laundering networks are global and pervasive, and they must be dismantled,” highlighting the national security implications of this criminal partnership.
The Chinese networks have revolutionized cartel financing by replacing traditional bulk cash smuggling with sophisticated digital transfers and trade-based laundering schemes. Financial institutions received detailed typology warnings about suspicious transaction patterns involving shell companies, cryptocurrency exchanges, and cross-border wire transfers. This represents a fundamental shift in how cartels move their proceeds, making detection significantly more challenging for traditional banking compliance systems.
Zhang Case Exposes International Scope
Zhi Dong Zhang’s case exemplifies the scale and sophistication of Chinese-facilitated cartel money laundering operations across international borders. The Chinese national allegedly laundered over $150 million for both the Sinaloa Cartel and Jalisco New Generation Cartel before dramatically escaping Mexican custody in July 2025. His fugitive status and subsequent international manhunt demonstrate the challenges law enforcement faces when pursuing transnational financial criminals operating across multiple jurisdictions.

Zhang’s network utilized complex webs of shell companies, cryptocurrency platforms, and legitimate businesses to obscure the criminal origins of cartel proceeds. The case highlights how Chinese money laundering facilitators have become indispensable to cartel operations, providing services that enable the continued flow of fentanyl into American communities. Treasury officials stressed that targeting these financial facilitators is essential to disrupting cartel operations at their core, cutting off the financial lifelines that sustain their deadly activities.
