Cash, Cartels, and the Chinese Connection: How Drug Money Flows into American Banks

Federal Investigators Uncover a Sophisticated Laundering Network Fueling the U.S. Drug Trade Through Teller Windows Across Los Angeles
LOS ANGELES — In a sweeping federal investigation that reads like a thriller, U.S. law enforcement has exposed a transnational money laundering operation linking Chinese underground bankers with Mexico's deadliest drug cartels. The operation, which involved the regular deposit of six-figure sums—often in gym bags stuffed with cash—into major U.S. financial institutions, highlights a dangerous evolution in global financial crime.
The laundering ring's primary targets? Mainstream bank branches belonging to JPMorgan Chase, Citibank, and Bank of America, across Los Angeles County. The financial system, it seems, has become the silent accomplice in a multi-billion-dollar drug and capital flight scheme stretching from Shanghai to Sinaloa to California.
A Modern Money Laundering Blueprint
At the center of the conspiracy is a mutually beneficial relationship between Chinese money brokers and Mexican cartels. The cartels needed to 'clean' the massive amounts of U.S. currency made from fentanyl, methamphetamine, and cocaine sales. Simultaneously, Chinese nationals, restricted by China's strict capital controls, sought methods to get large sums of money out of the country.
The method is simple, yet devastatingly effective: Drug money in U.S. dollars is handed to Chinese operatives on American soil. That money is deposited into U.S. bank accounts under front companies or borrowed names. Chinese citizens inside China pay the equivalent value in yuan to launderers through apps like WeChat Pay or Alipay. Cartels retrieve clean funds in pesos, bitcoins, or property from Chinese-controlled accounts in Mexico or other jurisdictions.
By separating the currency movements from physical cross-border transactions, criminals bypass customs enforcement, anti-money laundering (AML) systems, and traditional detection models.
Bags of Cash and Teller Blind Spots
Federal court documents reveal that over $300 million was laundered using this strategy between 2019 and 2023. Deposits were frequently made in structured amounts just below the $10,000 CTR (Currency Transaction Report) threshold to avoid automatic reporting.
Individuals often walked into retail bank branches across Alhambra, Monterey Park, Arcadia, and other L.A. suburbs with grocery bags, backpacks, or duffel bags filled with tightly rubber-banded $100 bills.
A former branch manager, speaking anonymously, recalled, 'The deposits didn't make sense. We saw someone walk in with $200,000 in cash, claiming it was for a 'retail export business,' but there were no corresponding wire transfers or invoices. We flagged it, but nothing ever came of it internally.'
The same pattern repeated across institutions, and whistleblower reports indicate internal compliance teams either missed or ignored red flags in dozens of locations.
Case Study: U.S. v. Chen & Zhen (2024)
A major federal indictment filed in Los Angeles in late 2024 highlights the operations of Justin Zhen, a Chinese-American real estate developer, and his associate, Hao Chen, an international logistics manager. According to the Department of Justice, the two operated a network of couriers—mostly international students or recent immigrants-who deposited cartel cash into more than 50 different accounts in 12 banks across Southern California.
Case Facts: Total laundered funds: $84 million
$84 million Banks used: Chase (Alhambra), Bank of America (Pasadena), Citibank (Rowland Heights)
Chase (Alhambra), Bank of America (Pasadena), Citibank (Rowland Heights) Period: 2021–2023
2021–2023 Seized evidence: 27 burner phones, 11 fake passports, and $2.1 million in U.S. currency
Undercover agents captured footage of couriers rehearsing deposit conversations, being trained to avoid suspicion, and using rotating IDS. Zhen allegedly boasted on a recorded call, 'You can launder $10 million without a single wire transfer.'
Underground Banking Meets High-Stakes Laundering
Chinese underground banking systems, often called fei qian (flying money), have existed for centuries. But today's version has gone digital, blending cryptocurrency, WeChat payments, and virtual private wallets. These networks thrive in the grey areas of international finance, notably where Chinese law prohibits outbound transfers over $50,000 per year per citizen.
The cartels have capitalized on this by offering access to offshore liquidity, promising launderers quick profits for helping cycle dirty money into Asia's shadow economy.
The result is a parallel global economy in which vast sums move without touching the regulated financial system but still manage to pass through trusted institutions.
National Response and Policy Failures
The U.S. Treasury Department, the Federal Bureau of Investigation, and the Office of the Comptroller of the Currency have launched joint investigations into the banks involved. While no charges have been filed against the financial institutions as of May 2025, the scrutiny is intense.
Senator Elizabeth Warren (D-MA) called for immediate hearings, stating, 'This is not just a regulatory failure. It's a national threat when fentanyl profits are flowing freely through American banks.'
A joint task force, including the FBI, DEA, and Homeland Security Investigations (HSI), has since been established to focus solely on Chinese money laundering and cartel collaborations in the U.S.
Case Study: The Fresno Drop-Off
In another ongoing case, DEA agents intercepted a courier who had driven from Las Vegas to Fresno carrying $600,000 in cash wrapped in heat-sealed food storage containers. The courier had instructions to deposit the funds in $9,000 increments across five banks within two days.
Digital logs show that the operation was coordinated via WeChat voice notes, using code names like 'water delivery' and 'temple donations.' Surveillance later uncovered a dozen similar couriers operating in California's Central Valley, each believed to have laundered between $2 million and $5 million over a year.
The Human Cost of Dirty Money
Behind every laundered dollar is a trail of overdose deaths, broken communities, and shattered families. Fentanyl, the cartels' product of choice, has killed more than 70,000 Americans per year, according to the CDC.
When drug profits are laundered successfully, cartels reinvest in larger shipments, deadlier chemicals, and more sophisticated smuggling techniques. By facilitating laundering—knowingly or not—banks indirectly enable the scourge law enforcement is fighting to stop.

A Call for Reinforcement, Not Just Reform
The Chinese cartel laundering pipeline has revealed gaping holes in the U.S. anti-money laundering regime—holes that have allowed billions in criminal proceeds to pass through the front doors of some of America's largest banks.
As regulators scramble to modernize detection systems and enforce stricter oversight, financial institutions must shift from reactive to proactive, from automated red flagging to human-centred risk evaluation.
Because when cartels walk in with bags of cash and walk out with digital legitimacy, the system is broken.
