Chinese Nationals: US Navy Spying Duo Sentenced to Prison

• Two Chinese nationals, Liren Lai and Yuance Chen, received two-and-a-half-year prison sentences for spying on U.S. Navy personnel and facilities.
• They acted on behalf of China's Ministry of State Security, gathering intelligence, recruiting assets, and facilitating clandestine cash payments.
• Both pleaded guilty to conspiracy to act as agents of a foreign government without notifying the attorney general.
• Their activities included photographing U.S. Navy installations, collecting personal information on service members, and executing multiple 'dead drop' cash transactions.
• The operation, which began as early as 2015, involved covert communications and extensive travel between the U.S. and China before their arrest in June 2025.

The sentences handed down to Lai and Chen serve as a clear demonstration of the U.S. government's resolve to hold accountable anyone who poses a similar threat to the nation, particularly those involved in conspiracy foreign agent US activities.

Two Chinese nationals recently received prison sentences for their involvement in an intelligence operation targeting U.S. Navy personnel and facilities. Liren "Ryan" Lai, 40, and Yuance Chen, 39, were found to have gathered sensitive information, recruited potential assets, and facilitated covert financial transactions on behalf of China's Ministry of State Security. This outcome underscores the severe legal ramifications for individuals engaged in such activities against American national security interests.

U.S. District Judge Jon Tigar imposed a sentence of two and a half years in prison for both Lai and Chen, which will be followed by three years of supervised release. The Department of Justice confirmed that both individuals had pleaded guilty to charges of conspiracy to act as agents of a foreign government without prior notification to the attorney general, a critical aspect of the legal framework governing foreign influence in the United States. The case highlights a persistent effort by foreign entities to compromise U.S. military assets and intelligence.

The intelligence-gathering operation, which the Department of Justice indicates began as early as 2015, involved a sophisticated network and various clandestine methods. Lai, a resident of China, traveled to the United States multiple times using visitor visas, where he played a key role in recruiting Chen into the intelligence network. Chen, who has been a lawful permanent resident of the United States since his marriage to a U.S. citizen in 2019, then assisted Lai in identifying and developing intelligence assets, as well as executing "dead drop" cash payments.

Specific instances of their activities include a 2022 incident where, while both men were in China, they helped arrange a $10,000 cash payment left in a backpack within a locker at a recreational facility in Livermore, California. That same year, Chen collected information on U.S. military installations and personnel under the direction of Lai and other Chinese intelligence officers. This included photographing U.S. Navy installations in Bremerton, Washington, and capturing images of sailors and recruits at Navy recruiting stations across Southern California, many of whom reportedly listed their hometowns in China. Chen also compiled personal identifying information on Navy civilian employees and maintained biographical data on potential intelligence targets, subsequently attempting to recruit these individuals.

The operation continued with further efforts to maintain covert communications and expand their intelligence gathering. In 2023, Lai traveled to the United States specifically to provide Chen with a cellphone for secure, covert communication with Chinese intelligence officials. Chen, in turn, made trips to China in both 2024 and 2025, where he met with intelligence officers and received additional assignments related to spying on U.S. service members.

Lai also returned to the United States in 2025 to carry out more assignments for the Chinese government, including another dead drop of $20,000 in a Phoenix parking garage. An earlier $20,000 dead drop had been made in San Francisco in 2024 by an unnamed co-conspirator. Both Lai and Chen were ultimately apprehended in June 2025 during an FBI operation, bringing an end to their involvement in this extensive espionage effort. The indictment also references two other unnamed co-conspirators, along with multiple unnamed Chinese intelligence officers and assets, indicating a broader network.

U.S. Attorney for the Northern District of California, Craig Missakian, emphasized the gravity of the defendants' actions, stating that they were directed by a foreign intelligence service with the intent to undermine U.S. national security. The successful prosecution and sentencing of these Chinese nationals for US Navy spying underscore the commitment of federal law enforcement to counter such threats.

Missakian highlighted that his office and federal partners are continuously vigilant in preventing adversaries from compromising national security. The sentences handed down to Lai and Chen serve as a clear demonstration of the U.S. government's resolve to hold accountable anyone who poses a similar threat to the nation, particularly those involved in conspiracy foreign agent US activities. This case, involving the Liren Lai Yuance Chen sentencing, sends a strong message regarding the consequences of engaging in espionage against the United States.

This case underscores the severe legal ramifications for individuals acting as unregistered foreign agents, particularly when targeting national security interests. Lawyers should advise clients, especially those with international ties or access to sensitive information, on compliance with foreign agent registration laws and the heightened risks of espionage.
