Chinese drug kingpin brother Wang arrested after plot to flee to Russia

In a statement late Thursday night, the Cuban government said it had extradited Chinese national Xie Dong Zhang to authorities in Mexico. Hours later, Mexico’s security chief subsequently confirmed his extradition to the United States on drug-trafficking and money-laundering charges.

A months-long, daring escape attempt by one of the world’s most wanted fugitives has come to an abrupt end.

Xie Dong Zhang, known by various aliases including Brother Wang, Pancho and HeHe, is accused by the US Department of Justice of masterminding a large international fentanyl trafficking and money laundering ring spanning several nations, but particularly China, Mexico and the US.

The list of charges against Mr. Zhang is long but brief, with US prosecutors and the Mexican attorney general’s office accusing him of being a major player in the global drug trade. They say he laundered millions of dollars in drug money for both the Sinaloa Cartel and the New Generation Jalisco Cartel (CJNG) as part of a worldwide drug distribution network.

“Brother Wang can be seen as a key link in the pre-cursor chemical sourcing for fentanyl between Mexican cartels and Chinese chemical companies”, explains Mike Vigil, a former DEA agent who was also instrumental in converting drug funds into cryptocurrency.

If convicted, Xi Dong Zhang can expect to share the same fate as other drug kingpins such as Joaquin ‘El Chapo’ Guzman and Ismael ‘El Mayo’ Zambada in a high-security facility in the United States.

But how ‘Brother Wang’ ended up in custody in Havana is an extraordinary story that involves escaping detention in Mexico City, punching a hole in a wall, taking a private jet to Cuba and finally a failed attempt to enter Russia.

In October 2024, Xi Dong Zhang was arrested in a joint security operation in Mexico City. He was initially held in a maximum security prison but was later granted house arrest by a judge – a decision President Claudia Sheinbaum called “disgraceful”.

The Wang brothers’ escape had all the hallmarks of another embarrassment for Mexico: A man considered a key cog in the drug-trafficking system could disappear right under the noses of the Mexican authorities tasked with protecting him. El Chapo Guzmán accomplished this feat twice, much to Washington’s dismay, before finally handcuffing him and putting him on a plane to America.

The fact that Mexican officials were able to retrieve their prisoner and send him north came down to two things – an apparent stroke of luck in Russia and the strength of Mexico’s security ties with Havana.

When Zhang arrived in Cuba in July 2025, he took the next step toward reaching a country that does not have an extradition treaty with the United States, officials said.

There is a direct commercial flight to Moscow from Havana and Zhang, they allege, was able to get a seat on it using forged documents. However, the documents did not follow him to the immigration authorities in Russia. It is reported that the Russians did not fully appreciate who was in their custody, and after briefly detaining him, they turned Zhang back and sent him back to Cuba.

Upon his second return to Havana, the Cuban security services now knew his true identity.

Security analysts believe that Cuban authorities held him for months for thorough interrogation before sending him back to Mexico and inevitably to the United States. Mexico’s Public Security Secretary, Omar Harfuch, was quick to thank Cuba for its cooperation on ‘Brother Wang’ – finally, for letting go of its blushes over another escaped high-profile prisoner.

As always after the arrests of alleged kingpins, the question is how much their removal will affect the global drug trade.

Given that the Wang brothers have spent the past year either in prison, under house arrest or on the run, the question may be moot, Mr. Vigil said, because his absence has been widely felt in Mexico’s criminal underworld:

“It won’t really have an effect because the cartels already have people working for them who can replace the Wang brothers”, says Mr Vigil. “Even in the case of El Chapo Guzmán, a very big figure, he had no impact on the global drug trade”, he argues.

During his first year in office, US President Donald Trump has pressured his Mexican counterparts to do more on the issue of fentanyl trafficking, and President Sheinbaum’s administration has responded appropriately. She has significantly increased drug seizures over her predecessor, and her administration has sent dozens of convicted drug cartel members to the US to serve sentences there. It includes the names of several high-level drug lords, such as Rafael Caro Quintero, who was wanted for the 1985 murder of a DEA agent.

Her support on the fentanyl issue as well as on undocumented immigration is seen as Trump’s refrain from imposing the same level of trade tariffs on Mexico as other trading partners.

Brother Wang’s extradition would bring real satisfaction to Washington for vindicating a key figure in the Mexican cartel’s financial operations. This, in turn, will please the Sheinbaum administration in Mexico and strengthen its claim to be in lockstep with its US counterparts on security matters.

However, slowing or reducing the movement of precursor chemicals for fentanyl in any lasting way from China to the US will take more than a single human extradition.
