The “Fentanyl King” and a Global Supply Chain

Day 1

「フェンタニル・キング」とグローバルなサプライチェーン

Global fentanyl supply chain investigation

Fentanyl has become one of the deadliest drugs in the United States. The synthetic opioid is extremely powerful, and illegal versions of it have been linked to hundreds of thousands of overdose deaths over the past decade. Yet the drug rarely begins its journey inside the United States. Its production often depends on an international network connecting chemical suppliers, traffickers, criminal organizations, and distributors across several countries.

フェンタニルは、アメリカで最も致死的な薬物の一つとなりました。この合成オピオイドは極めて強力で、その違法な形態は過去10年で何十万人もの過剰摂取死と関連づけられてきました。しかしこの薬物がアメリカ国内で旅を始めることはまれです。その生産はしばしば、化学物質の供給業者、密売人、犯罪組織、流通業者を複数の国にわたってつなぐ国際的ネットワークに依存しています。

One man accused of playing a central role in this network is Chinese national Zhang Zhidong, also known as “Brother Wang” or the “Fentanyl King.” US authorities allege that he helped connect chemical suppliers in China with powerful drug cartels in Mexico. Those organizations could then manufacture fentanyl and move it across the US border. Zhang has pleaded not guilty and is awaiting trial in the United States.

このネットワークで中心的な役割を果たしたとされる人物の一人が、中国籍の張志東(Zhang Zhidong)です。別名「Brother Wang」または「フェンタニル・キング」とも呼ばれます。米国当局は、彼が中国の化学物質供給業者とメキシコの有力な麻薬カルテルをつなぐのを助けたと主張しています。そうした組織はその後フェンタニルを製造し、米国国境を越えて運ぶことができました。張は無罪を主張し、米国で裁判を待っています。

According to people familiar with the Mexican drug trade, Zhang first attracted attention because he could provide the chemicals and expertise needed to produce fentanyl on a large scale. He was reportedly intelligent, well connected, and skilled at building relationships between groups that did not always trust one another. In an illegal market divided by language, geography, and competing interests, a reliable intermediary can become enormously valuable.

メキシコの麻薬取引に詳しい人々によると、張が最初に注目されたのは、大規模にフェンタニルを生産するために必要な化学物質と専門知識を提供できたからです。彼は知性があり、人脈が広く、必ずしも互いに信頼し合わないグループの間に関係を築くのがうまかったと報じられています。言語、地理、競合する利害によって分断された違法市場では、信頼できる仲介者が極めて大きな価値を持ちえます。

The alleged operation also shows how the fentanyl trade resembles a modern global business. Raw materials may come from one country, production may take place in another, and the final product may be sold thousands of kilometres away. Money, information, and chemicals move through separate channels, making it difficult for law-enforcement agencies to identify the entire network at once. Removing one supplier does not necessarily expose every producer, transporter, or distributor involved.

この疑惑のオペレーションはまた、フェンタニル取引が現代のグローバルビジネスとどれほど似ているかを示しています。原材料はある国から来て、生産は別の国で行われ、最終製品は何千キロも離れた場所で販売されることがあります。金、情報、化学物質は別々の経路を通じるため、法執行機関がネットワーク全体を一度に特定するのは難しくなります。一人の供給業者を排除しても、関与するすべての生産者、輸送業者、流通業者が露呈するとは限りません。

Zhang’s arrest in November 2025 was therefore presented as a major achievement. US authorities believed they had detained an important figure in the international fentanyl trade. However, people inside the cartel world reportedly viewed the arrest differently. They acknowledged that it had created confusion and temporarily affected business, but they also suggested that the organization had already begun looking for another person with similar connections.

したがって、2025年11月の張の逮捕は大きな成果として示されました。米国当局は、国際的なフェンタニル取引の重要人物を拘束したと考えていました。しかし、カルテル世界の内部の人々は逮捕を違って見ていたと報じられています。混乱を生み、一時的にビジネスに影響したことは認めた一方で、組織はすでに同様のコネクションを持つ別の人物を探し始めていたとも示唆しました。

This raises a difficult question. Was Zhang an irreplaceable criminal mastermind, or simply one highly effective participant in a much larger system? Calling someone a “kingpin” may suggest that an entire organization depends on a single leader. In reality, profitable illegal markets often develop backup suppliers, alternative routes, and replacement personnel precisely because arrests are an expected part of the business.

これは難しい問いを投げかけます。張は替えのきかない犯罪の頭脳だったのか、それともはるかに大きなシステムの中の、きわめて有能な参加者の一人にすぎなかったのか。「キングピン」と呼ぶと、組織全体が一人の指導者に依存している印象を与えかねません。現実には、利益の出る違法市場は、逮捕がビジネスの予想される一部だからこそ、しばしばバックアップ供給業者、代替ルート、交代要員を育てます。

Zhang remains in federal custody, and the allegations against him have not yet been proven in court. His case may reveal more about how the international fentanyl trade operates. But even a successful prosecution may not be enough to stop a market sustained by flexible criminal networks and continuing demand.

張は連邦当局の拘束下にあり、彼に対する疑惑はまだ法廷で証明されていません。彼の事件は、国際的なフェンタニル取引がどのように機能しているかについて、さらに多くのことを明らかにするかもしれません。しかし訴追が成功しても、柔軟な犯罪ネットワークと続く需要によって支えられている市場を止めるには十分でないかもしれません。

The arrest of the so-called Fentanyl King may have removed a powerful intermediary. Whether it can significantly reduce the flow of fentanyl is a much larger question.

いわゆるフェンタニル・キングの逮捕は、強力な仲介者を排除したかもしれません。それがフェンタニルの流れを大きく減らせるかどうかは、はるかに大きな問いです。

Vocabulary

  1. synthetic opioid — a powerful pain-relieving drug produced through chemical processes rather than obtained directly from a plant. Example: Fentanyl is a synthetic opioid that can be far stronger than morphine.
