TLDR
- The US charged Stanley Yi Zheng and two US citizens over an alleged scheme to smuggle advanced AI chips to China through Thailand.
- Prosecutors said the AI chips were American-made and subject to US export controls.
- A federal grand jury in Ohio indicted two Chinese companies and six Chinese nationals in a fentanyl precursor trafficking case.
- Authorities alleged customers sent cryptocurrency to wallets controlled by the defendants, with funds later moved to overseas financial institutions.
- The fentanyl case was brought under the FBI’s Operation Box Cutter, which targets international drug trafficking networks.
United States authorities on Wednesday announced two separate criminal cases involving Chinese nationals and companies, one tied to the alleged smuggling of advanced American AI chips to China and another focused on fentanyl precursor sales, cryptocurrency payments and money laundering. The cases were disclosed as Washington continues to tighten export controls on sensitive technology and increase pressure on networks linked to the fentanyl trade.
In the export control case, the US Department of Justice charged Chinese national Stanley Yi Zheng, from Hong Kong, along with two US citizens, Matthew Kelly and Tommy Shad English. Prosecutors alleged that the three conspired to obtain export-controlled AI chips made in the United States and route them through Thailand for shipment to China. According to the allegations, the chips were worth millions of dollars and were subject to US restrictions aimed at limiting China’s access to advanced semiconductor technology.
The charges came at a time of continued friction in US-China relations, with artificial intelligence and semiconductor supply chains remaining central areas of competition. The developments were announced on the same day President Donald Trump publicised new mid-May dates for an expected summit with China, placing the criminal cases against a wider diplomatic backdrop.
AI chip smuggling case centers on export controls
US prosecutors said the alleged scheme involved efforts to circumvent federal export controls on high-performance chips with potential military or strategic value. American officials have expanded these controls in recent years as part of a broader effort to restrict China’s access to advanced computing power and semiconductor tools.
The Justice Department has not yet secured convictions in the case, and the charges remain allegations at this stage. If the case proceeds, it is expected to draw attention to how US authorities monitor third-country routes, including Southeast Asian channels, that may be used to move restricted technology to buyers in China.
In a separate action, a federal grand jury in Ohio indicted two Chinese pharmaceutical companies and six Chinese nationals over alleged fentanyl precursor trafficking and laundering of proceeds. The companies named in the indictment were Shandong Believe Chemical Company Pte Ltd. and Shandong Ranhang Biotechnology Co. Ltd. Prosecutors alleged that the defendants sold precursor chemicals and cutting agents used in fentanyl production to buyers in the United States and abroad.
Ohio indictment targets crypto payment networks
According to the indictment, customers were instructed to send cryptocurrency payments to digital wallets controlled by the defendants. Authorities said the funds were then moved through multiple wallet addresses before being transferred to overseas financial institutions, a pattern investigators commonly describe as a way to obscure the source and destination of funds.
The case was brought under the FBI’s Operation Box Cutter, an initiative focused on dismantling international fentanyl trafficking networks. Three defendants were also charged with attempting to provide material support to a Mexican drug cartel that the United States has designated as a foreign terrorist organization.
US authorities said the companies marketed substances including medetomidine, an animal tranquilizer that can be used to dilute fentanyl and increase the quantity available for street sales. Prosecutors said one kilogram of fentanyl could be expanded many times over when mixed with such agents, increasing the number of doses distributed in illegal markets.
Drug trafficking case expands focus beyond cartels
The Ohio case reflects a broader enforcement approach that reaches beyond cartel operators and street distributors to include foreign suppliers, payment handlers, and wallet operators. Investigators said cryptocurrency played a central role in the payment chain, enabling cross-border transactions between chemical sellers and trafficking networks.
Research cited in the reporting said China-based precursor vendors have increasingly accepted crypto payments, with stablecoins often used at the first stage of the transfer process. The same research found that on-chain inflows to these vendors rose in 2025 from the previous two years, pointing to continued use of digital assets in the illicit supply chain.
If convicted, the defendants in the fentanyl precursor case could face severe prison terms, including up to life for drug trafficking offenses and up to 20 years for money laundering and terrorism-related charges. Together, the two cases show how US enforcement agencies are pursuing China-linked investigations across both advanced technology controls and transnational narcotics financing.
