US Navy Sailor Convicted for Espionage in Relations with Chinese Agent
Jinchao Wei, a US Navy sailor, is found guilty of espionage for leaking military secrets to a Chinese intelligence officer.
A US Navy sailor has been found guilty of espionage for selling military secrets to a Chinese agent he was recruited by through social media. Jinchao Wei, 25, has been convicted on multiple counts including espionage and unlawful export of classified data concerning US Navy operations. The ruling signifies a severe breach of trust deemed by US Attorney Adam Gordon, who condemned Wei’s actions for undermining both the safety of American sailors and national security.
Wei, a machinist's mate and naturalized citizen, gained access to sensitive information about the USS Essex and other ships in the Pacific Fleet. Following his arrest in August 2023 upon arrival at work, evidence emerged during the trial showcasing a series of communications with his handler, referred to as "Big Brother Andy.” Wei's reliance on encrypted messaging apps facilitated covert exchanges, and the evidence detailed both military information shared and monetary transactions that exceeded $12,000.
Text messages uncovered during the trial indicated Wei’s awareness of his betrayal, with comments made to his mother reflecting on his espionage activities. The relationship began when a Chinese intelligence officer reached out to him in February 2022 with a guise of being a naval enthusiast. Wei not only photographed and shared the location of US Navy ships but also discussed specific operational issues.
Set to be sentenced on December 1, Wei faces the possibility of life imprisonment. His case is part of a larger narrative of espionage threats within the US military, echoing concerns raised by the recent arrest of Petty Officer Wenheng Zhao. The latter also faced charges for selling sensitive military information, highlighting a persistent vulnerability to espionage efforts by foreign entities. As investigations continue, the implications of Wei’s actions are felt on multiple fronts, raising alarms over the integrity of military personnel against foreign manipulation.
