A Chinese national who once warned his own supplier that American soil was too dangerous for a meeting has pleaded guilty to trying to smuggle US military communications equipment to China, after flying to a US Pacific island where federal agents were waiting.
Dingwei Chen had one rule: he would not meet on American ground. Saipan, he told his supplier, was “not a safe place to meet.” Yet in October 2025 he boarded a flight there anyway. On 10 August 2026, the 29-year-old pleaded guilty in a federal court in Salt Lake City to violating the Arms Export Control Act. US District Judge David Sam accepted the plea, and sentencing follows on 19 October — Chen faces a maximum of 20 years.
The Shopping List
Chen wanted satellite modems and radios, though not the commercial variety. The hardware he sought is built by American firms for the US military. According to a Homeland Security Investigations affidavit, the order covered ten modems from manufacturers L3Harris, Viasat and Comtech.
That kind of equipment sits on the US Munitions List, which falls under the Arms Export Control Act — meaning nobody may ship it abroad without a licence from the State Department’s Directorate of Defense Trade Controls, an office that almost never approves military exports to China.
A Deal That Refused to Die
The scheme began with ordinary paperwork. A Chinese company signed two contracts with the US subsidiary of a Swiss firm, whose general manager later became Chen’s co-conspirator. Investigators spotted the purchase in March 2025. A down payment of more than $42,000 arrived in April, and in May the American subsidiary wrote back with bad news: it could not legally export the goods.
Most buyers would have walked away. These buyers redrew the map instead, first proposing to route the modems through Switzerland, then suggesting collection in Saipan, and finally settling on smuggling the cargo through Mexico and entering via Texas.
The Man on the Other End
On 3 July 2025, the subsidiary handed the conversation to someone new — a Utah-based undercover agent. The two men moved to an encrypted app, where Chen identified himself as the buyer of the ten modems and laid out his conditions: he refused to meet in any Five Eyes country, argued Singapore would be far safer, or suggested the agent could deliver to intermediaries inside America.
Chen then volunteered something prosecutors would enjoy — that he had smuggled goods out of the United States before. That single boast handed investigators both a motive and a history.
Cold Wallets and Bigger Promises
The payments soon changed shape, with cash giving way to cryptocurrency. Cold wallets worked like anonymous bank accounts, the buyers wrote, leaving no trace, and Chen transferred more than $32,000 in Tether. He was also thinking well beyond the first order, claiming the ten modems were merely an opening and that he had access to tens of millions of dollars more.
Homeland Security spotted his travel plans on 3 October 2025. Three days later, agents arrested him in Saipan, acting on a warrant a magistrate judge in Utah had already signed. Chen’s lawyer has declined to comment.
Why Washington Cares
Officials treated the plea as a warning shot. Assistant Attorney General John Eisenberg said Chen tried to “divert sensitive U.S. military technologies” to China. James Ives, who directs the Defense Criminal Investigative Service, made the practical case: advanced communications keep troops alive on modern battlefields, he argued, which is exactly why adversaries covet them.
Spiros Karabinas of Homeland Security Investigations framed the outcome differently, saying agents had dismantled an illicit procurement network. Christopher Magnani is prosecuting the case for the Justice Department’s Counterintelligence and Export Control Section. Notably, the department did not accuse the Chinese state of ordering the purchase — court records describe a commercial network hunting black-market suppliers.
A Pattern, Not an Incident
Chen’s case hardly stands alone. Prosecutors announced Operation Gatekeeper in December 2025, an inquiry that disrupted the smuggling of roughly $160 million in Nvidia chips. Then, in March 2026, an indictment named three men linked to Super Micro Computer, alleging they diverted AI servers worth billions to Chinese customers.
The Disruptive Technology Strike Force now coordinates much of this work — different cargo, but the same playbook of friendly intermediaries, third countries and quiet money.
Beijing has answered in kind. In June 2026, Chinese ministries restricted 56 American entities. Export controls now cut both ways.
