💬KEY QUOTE: “The defendant’s actions represent an egregious betrayal of the trust placed in him as a member of the U.S. military.” – U.S. Attorney Adam Gordon
🎯IMPACT: The conviction highlights the ongoing threat posed by foreign intelligence efforts targeting U.S. military personnel.
Jinchao Wei, a 25-year-old United States Navy sailor stationed at Naval Base San Diego, was convicted on Wednesday by a federal jury of six charges, including espionage and unlawful export of defense-related technical data. Wei, who was arrested in August 2023, sold sensitive Navy information to a Chinese intelligence officer for a total of $12,000 over an 18-month period.
Evidence presented at trial revealed that Wei, aware of the espionage nature of his actions, communicated with the intelligence officer using encrypted messaging apps and provided detailed technical and operational information about U.S. Navy ships, including the U.S.S. Essex, a Wasp-class amphibious assault ship. This information included manuals, photographs, and descriptions of the ship’s systems and defense capabilities, many of which were marked with export-control warnings.
Wei was recruited in February 2022 by a Chinese intelligence officer who initially posed as a naval enthusiast. Despite recognizing the suspicious nature of the contact, Wei transitioned his communications to encrypted platforms and began providing sensitive information. He even admitted during his post-arrest interview that his actions constituted espionage, stating, “I’m screwed.”
U.S. Attorney Adam Gordon emphasized the severity of Wei’s betrayal, stating, “By trading military secrets to the People’s Republic of China for cash, he jeopardized not only the lives of his fellow sailors but also the security of the entire nation and our allies.” The Federal Bureau of Investigation (FBI) and Naval Criminal Investigative Service (NCIS), which led the investigation, stressed the lengths to which the Chinese government will go to undermine U.S. national security.
Wei is scheduled for sentencing on December 1, 2025. The charges carry severe penalties, including life in prison for the espionage counts.
