A former US Navy sailor has been sentenced to more than 16 years in prison after being convicted of selling sensitive naval information to a contact linked to Chinese intelligence, marking one of the most severe espionage cases involving the US military in recent years.
A federal judge in San Diego on Monday sentenced Jinchao Wei, 25, to 200 months in prison after a jury found him guilty in August on six criminal counts, including espionage. Prosecutors said Wei sold technical and operational manuals related to US Navy ships and onboard systems, information they argued could have compromised national security if exploited by a foreign power.
According to the US Department of Justice, Wei was paid more than US$12,000 in exchange for the materials he provided. The documents included detailed guidance on ship operations and internal systems, which prosecutors said could offer valuable insight into how US naval vessels function in real-world conditions.
Wei served as a sailor in the US Navy before his arrest and was stationed in California at the time of the offenses. Court records show that he maintained contact with an individual prosecutors identified as an intelligence officer working on behalf of China. Authorities said the relationship involved deliberate efforts to collect and transmit information that was not intended for public release.
During the sentencing hearing, prosecutors described Wei’s actions as a serious breach of trust, emphasizing that members of the armed forces are entrusted with sensitive information and expected to safeguard it. They argued that even though the payments Wei received were relatively modest, the potential damage to US military readiness and security was significant.
Defense attorneys sought leniency, pointing to Wei’s age and personal circumstances, and argued that he did not fully grasp the consequences of his actions. They also said there was no evidence that the information he passed on had directly led to harm. The judge, however, sided largely with the prosecution, saying the seriousness of the crimes warranted a lengthy sentence.
The case comes amid heightened concern in Washington over espionage and foreign intelligence activity targeting the US military and defense industries. US officials have repeatedly warned that China is seeking to acquire sensitive information through both cyber means and human sources, a claim Beijing routinely denies.
In recent years, the US has stepped up counterintelligence efforts, particularly within the armed forces, after several cases involving the transfer of sensitive information to foreign contacts. Officials say these prosecutions are intended both to punish wrongdoing and to deter others from similar actions.
The sentencing also reflects a broader trend of tougher penalties in espionage cases, especially those involving military secrets. Legal experts note that courts have increasingly emphasized deterrence and national security considerations when imposing sentences, even when the financial gains involved are relatively small.
Wei’s conviction and sentencing were announced by federal prosecutors in California, who said the case demonstrated the government’s commitment to protecting classified and sensitive defense information. They urged service members and defense contractors to remain vigilant against foreign intelligence recruitment efforts.
With the sentence now handed down, Wei will serve more than 16 years in federal prison, followed by supervised release. The case stands as a stark reminder of the risks posed by insider threats and the severe consequences faced by those who betray military trust for personal gain.
