In a five-year investigation, U.S. officials have revealed a sophisticated partnership between one of Mexico's most notorious drug cartels, the Sinaloa Cartel, and Chinese underground banking groups in the United States. Federal prosecutors announced on Tuesday that the collaboration was aimed at laundering money from the sale of fentanyl, cocaine, and other drugs.

According to the prosecutors, associates of the Sinaloa Cartel conspired with Chinese groups to conceal over $50 million in drug profits, with much of the money being processed in the Los Angeles area. The investigation resulted in the charging of two dozen people, some of whom had initially fled the country but were apprehended with the help of Chinese and Mexican law enforcement.

At a news conference, Drug Enforcement Administration official Anne Milgram described the investigation as a revelation of a new criminal partnership between the Sinaloa Cartel and Chinese nationals, who facilitated money laundering for the cartels. The lead defendant in the case is identified as Edgar Joel Martinez-Reyes, a 45-year-old resident of East Los Angeles. Prosecutors allege that he managed couriers responsible for collecting drug cash in the Los Angeles region. Martinez-Reyes is said to have partnered with the leader of the Chinese money laundering operation, traveling to Mexico with him to negotiate contracts with the cartel.

The scheme, as reported by prosecutors, relied on the high demand for U.S. currency from wealthy Chinese nationals. Chinese government regulations restrict individuals from transferring more than $50,000 per year out of the country. Consequently, the money laundering operation involved transferring funds through Chinese bank accounts, with the Chinese sellers receiving the equivalent in U.S. dollars. The laundered funds were then used by Chinese nationals to purchase real estate, luxury items, and pay for tuition. Cryptocurrency transactions were also utilized to facilitate the movement of drug money. The funds sent to China were utilized to procure precursor chemicals for the production of drugs like fentanyl and methamphetamine, which were then sent to Mexican drug cartels.

Officials noted that the Chinese money brokers charged significantly lower commission fees compared to traditional money launderers, providing a more cost-effective approach to moving money. This method proved to be more advantageous than previous techniques such as smuggling cash across the U.S.-Mexico border or utilizing banks and businesses.

The investigation highlights the troubling cycle of destruction, as drugs sold in the United States are used to fund the procurement of precursor chemicals, which are then employed to produce even more drugs that enter the country. Federal law enforcement has been collaborating closely with China's Ministry of Public Security since a meeting between President Joe Biden and Chinese leader Xi Jinping in Woodside, California, last November.

Out of the 24 defendants implicated in the case, at least 22 have been arrested, according to officials. Charges against them include conspiracy to aid and abet the distribution of cocaine and methamphetamine, conspiracy to launder monetary instruments, and conspiracy to operate an unlicensed money-transmitting business. Most of those in custody are expected to be arraigned in the U.S. District Court in Los Angeles in the upcoming weeks.

In addition to the arrests, law enforcement authorities seized approximately $5 million worth of drugs, including over 300 pounds (135 kilograms) of cocaine, 92 pounds (41 kilograms) of methamphetamine, as well as other drugs and several firearms.

The investigation serves as a testament to ongoing efforts by U.S. officials and international partners to dismantle and disrupt criminal networks involved in drug trafficking and money laundering, safeguarding communities from the devastating consequences associated with these illegal activities.
