A federal Chinese espionage investigation involving a California real estate agent accused of spying for Beijing has uncovered a network of business and social connections linked to two major international criminal investigations: a money laundering operation involving Mexico’s Sinaloa Cartel and a multibillion-dollar cryptocurrency fraud empire based in Cambodia.
The connections, detailed in an Oct. 16 CBS News investigation, raise questions about the overlapping business networks connecting individuals suspected of Chinese intelligence activities with figures associated with organized crime.
Federal authorities have not established that the espionage allegations, cartel money laundering and Cambodian fraud operations were part of a coordinated conspiracy. Nevertheless, the investigation reveals how individuals connected to these separate cases operated within overlapping business and social circles in the United States.
Alleged Chinese espionage leads to cartel money laundering investigation
Wanying “Heather” Zhang, a 34-year-old real estate agent from Irvine, California, was arrested at Los Angeles International Airport on Oct. 4 while preparing to board a flight to China.
According to an Oct. 5 announcement from the U.S. Department of Justice, Zhang allegedly conducted surveillance on the family of Taiwanese President Lai Ching-te in September 2025 at the direction of Chinese government officials.

Federal investigators say Zhang traveled to China in June 2025, where she received instructions from Chinese officials before returning to the United States.
During a subsequent trip to the Seattle area, she allegedly photographed and recorded members of the Taiwanese president’s family outside their residence.
After identifying one of her surveillance targets, Zhang reportedly messaged a Chinese government contact: “Saw him, young male, it’s the young one.”
When the official requested an audio call, she responded: “I am videorecording.”
The FBI described the alleged operation as “a brazen plot directed by the Chinese government.”
However, the case took an unexpected turn when investigators examined Zhang’s relationship with Fatai Miao, a 54-year-old construction entrepreneur who allegedly accompanied her during the surveillance mission.
According to CBS News’ examination of federal court documents, Miao was a person of interest in the investigation and maintained longstanding connections with Zhang.
Miao was also the registered agent and organizer of Yuanjin Development & Construction LLC, a California company registered at a $4.5 million residence in Irvine.
That property had previously attracted attention from federal drug enforcement investigators.
Court documents reviewed by CBS indicate that the residence was allegedly used to store cash by a Chinese-linked money laundering organization associated with the Sinaloa Cartel.
In March 2023, Drug Enforcement Administration investigators observed a suspected member of the organization delivering a weighted red bag to the property. Authorities believed it contained proceeds from illegal activities.
The discovery connects the location to a much larger investigation into financial networks operating between the United States, Mexico and China.
In June 2024, the Justice Department announced charges against 24 individuals accused of participating in a conspiracy involving Chinese underground banking networks and the Sinaloa Cartel.
Federal prosecutors alleged that more than $50 million in drug trafficking proceeds moved between cartel associates and Chinese underground currency exchanges.
DEA Administrator Anne Milgram described the investigation as uncovering “a partnership between Sinaloa Cartel associates and a Chinese criminal syndicate operating in Los Angeles and China.”
The alleged operation exploited demand among Chinese nationals seeking to move money outside China’s financial system.
According to prosecutors, currency brokers accepted American dollars generated through illegal drug sales and made equivalent funds available through transactions involving Chinese bank accounts.
The arrangement allowed cartel associates to move profits while enabling customers in China to obtain dollars without relying on conventional international bank transfers.
The investigation also uncovered transactions involving luxury goods, real estate and cryptocurrency.
The financial questions surrounding Zhang extend beyond her association with Miao.
During an Oct. 7 court hearing, prosecutors alleged that Zhang had operated an unlicensed currency exchange business and transferred $190,000 in profits to a Chinese bank account.
However, federal authorities have not accused Zhang of participating in the cartel’s money laundering operation. Miao has also not been charged in connection with that investigation.
CBS reported that Miao traveled to China on a one-way ticket shortly before FBI agents searched his Irvine residence.
Business connections extend to Cambodia’s multibillion-dollar scam empire
The investigation uncovered another international connection through Miao’s business partner, Cheng Zhang.
According to corporate records examined by CBS News, Cheng Zhang was involved in Big Bow LLC, a California company jointly managed with M Capital Global California LLC.
The latter company is controlled by Chen Sokly, a businessman identified by investigative journalists as an alleged senior figure in Cambodia’s Prince Group.
In October 2025, U.S. prosecutors charged Prince Group chairman Chen Zhi with conspiracy to commit wire fraud and money laundering.
The Justice Department indictment and accompanying announcement accused the organization of operating forced-labor compounds across Cambodia, where trafficked workers were compelled to conduct cryptocurrency investment scams targeting Americans and other victims worldwide.
Assistant Attorney General John Eisenberg described the scale of the alleged operation, stating: “Trafficked workers were confined in prison-like compounds and forced to carry out online scams on an industrial scale.”
The Justice Department also filed a civil forfeiture action targeting approximately $15 billion in Bitcoin associated with the alleged fraud and money laundering operation, the largest such action in the department’s history.
The operation allegedly relied on more than fraudulent investment schemes.
Federal prosecutors claim Prince Group executives used bribery, intimidation and political connections to protect their operations from law enforcement.
In an investigation published by the Organized Crime and Corruption Reporting Project (OCCRP), journalists identified Chen Sokly as the individual described in federal court documents as “Co-Conspirator-2.”
According to prosecutors, the individual allegedly managed Prince Group’s internal risk-control operations and used corruption and violence to protect its criminal activities.
The indictment also alleges that Prince Group maintained relationships with corrupt Chinese law enforcement and intelligence officials.
Prosecutors described communications involving officials from China’s Ministry of Public Security and alleged arrangements with Ministry of State Security personnel to obtain advance warning of law enforcement actions.
These allegations suggest that Prince Group’s operators sought protection through corrupt relationships with individual Chinese officials. They do not establish that the Chinese government directed the group’s criminal activities.
The U.S. Treasury Department designated Prince Group a transnational criminal organization in October 2025, imposing sanctions on 146 associated individuals and entities.
At the time, Treasury Secretary Scott Bessent warned that “The rapid rise of transnational fraud has cost American citizens billions of dollars, with life savings wiped out in minutes.”
However, Prince Group has rejected the allegations.
A spokesperson told OCCRP that the company and its chairman were “targets of a coordinated international asset grab dressed up as law enforcement.”
Chen Sokly has not been charged in the U.S. Prince Group indictment.
The connections between Zhang and the Cambodian organization also extend into California’s luxury automobile and cryptocurrency circles.
In 2024, Zhang posted a photograph on the Chinese social media platform Xiaohongshu showing herself behind the wheel of a Bugatti Chiron.
CBS traced the vehicle to cryptocurrency trader Wenzhi “Wesley” Fei, who said he had borrowed it from Chen Sokly.
Photographs and videos reviewed by investigators showed Fei socializing with Sokly around expensive sports cars and a luxury yacht.
Fei also appeared at a property belonging to Brendon Luo, whom the U.S. Treasury sanctioned in June 2026 for his alleged involvement in Prince Group’s scam operations.
Fei has denied knowing Zhang personally and said he knew nothing about Sokly’s alleged criminal activities. He has not been charged with a crime.
The emerging picture is one of overlapping relationships involving real estate developers, cryptocurrency traders, luxury assets and individuals implicated in separate international criminal investigations.
Whether those relationships represent anything beyond shared business and social circles remains an unanswered question.
Meanwhile, federal prosecutors have warned that Chinese intelligence operations inside the United States represent an increasingly serious national security concern.
In an Oct.12 interview with Fox News Digital, First Assistant U.S. Attorney Bill Essayli described Chinese government-backed espionage as “extremely pervasive.”
He warned that Beijing was pursuing a long-term strategy of recruiting individuals, developing intelligence sources and obtaining American technology.
“They’re playing the long game,” Essayli said, describing China’s willingness to commit substantial resources to intelligence operations.
The Zhang investigation illustrates the challenges facing federal authorities as they examine covert foreign influence, underground financial networks and international organized crime operating within the United States.
While investigators have not established a coordinated criminal enterprise connecting the three cases, the documented relationships demonstrate how individuals implicated in vastly different investigations can occupy overlapping commercial and social networks.
