Chinese Graduate Behind Mexico's 'Fentanyl King' Extradited to US for Trial

(Central News Agency, Culiacan, 13th – comprehensive international report) Enrique, who claims to be a high-level coordinator of Mexico's Sinaloa drug cartel, revealed to the BBC how the raw materials for the deadly drug 'fentanyl' are transported from Chinese factories to Mexico—a supply chain built entirely by a man known as 'Brother Wang.'

According to the BBC, based on data from the U.S. Department of Justice, 'Brother Wang,' known as the 'Fentanyl King,' is a 39-year-old Chinese man named Zhang Zhidong (Zhang Zhidong, transliteration). He was arrested in Mexico in 2024, briefly escaped, but was recaptured last year and extradited to the United States to await trial.

Fentanyl is a synthetic opioid, 50 times more toxic than heroin. Only a few grains the size of salt can be lethal, killing tens of thousands annually, mostly in the United States.

Former U.S. President Trump labeled fentanyl traffickers as 'drug terrorists' and classified fentanyl and its components as weapons of mass destruction, imposing additional tariffs on China, Mexico, and Canada over fentanyl trade.

When Zhang appeared in court in New York last year, then-U.S. Deputy Attorney General Todd Blanche described him as 'one of the most dangerous drug traffickers in the world,' accusing him of 'running a global criminal enterprise that shipped large quantities of cocaine, fentanyl, and methamphetamine into the United States.'

Zhang denies the charges and is currently awaiting trial. His appointed lawyer declined to comment to the BBC, citing the ongoing legal proceedings.

However, members of Mexico's Sinaloa Cartel and former colleagues spoke to the BBC, offering insight into how a top-tier Chinese graduate became the crucial link between Chinese chemical manufacturers and Mexican drug labs.

Zhang graduated from Peking University's Spanish Department in 2010. A year later, he joined a Chinese mining company in Mexico, quickly rising to a senior position.

Alex (a pseudonym), who attended the same university and later worked at the same mining company, said Zhang was 'skilled in negotiation, resourceful, and adaptable to any environment.' Especially in Mexico, where business often involves underground forces like drug cartels, Zhang always managed to 'build relationships with influential locals, both official and unofficial.'

The mining company collapsed in 2013. Alex returned to China, but Zhang chose to remain in Mexico.

Enrique, a cartel member, said Zhang later entered the drug trade, forming a romantic relationship with a female relative of a drug lord, which allowed him to penetrate the cartel's inner circle.

Luis (a pseudonym), another cartel member responsible for errands, said in 2019 he was assigned to guard a meeting where Zhang 'came to pitch his product'—the chemical precursors needed to manufacture fentanyl. In his view, Zhang was the one who introduced fentanyl to the cartel and launched this business line.

Enrique explained the process of ordering chemical precursors from Zhang: Zhang would use his connections in China to obtain the materials, ship them to Mexico via air or sea freight, and then distribute them to drug producers in Sinaloa's underground labs.

According to investigations by Mexican security agencies, Zhang's illegal operations spanned the Americas, Europe, China, and Japan.

Mexican authorities allege Zhang was involved in smuggling and distributing over 1,000 kilograms of cocaine, 1,800 kilograms of fentanyl, and 600 kilograms of methamphetamine, with annual illicit drug proceeds exceeding $150 million USD (approximately NT$4.74 billion).

The U.S. Department of Justice released a press statement last year detailing the charges against Zhang. In addition to drug trafficking, he is accused of recruiting individuals to open bank accounts under the names of over 100 shell companies, collecting cash across the U.S., depositing it into these accounts, and wiring funds to other beneficiaries to launder money overseas.

After Zhang was arrested in Mexico on October 31, 2024, related drug trafficking activities abruptly ceased.

Cartel members in Culiacan admitted that after Zhang's arrest, obtaining drug-making materials became 'extremely difficult,' forcing the cartel to 'start from scratch and find new routes.' Enrique revealed they are now seeking a new contact—also a Chinese national.

Around the same time, the U.S. Drug Enforcement Administration (DEA) began detecting a drop in fentanyl purity, indicating that many Mexican fentanyl producers are struggling to obtain key precursor chemicals. (Translation: Chang Ming-Hsuan) 1150713
