American researcher Youlin Chen, known for his studies on North Korea’s nuclear weapons tests, is facing trial in China on espionage charges. This charge can potentially lead to a death sentence under Chinese law, according to his wife and advocacy groups. Chen, 54, was held by Chinese authorities almost two years ago, as reported by Reuters. The report cites his wife, Yufang Rong, and nonprofit organizations dedicated to helping those regarded as wrongly detained abroad.
Chen’s case marks the second high-profile instance of a U.S. citizen being charged with espionage in China this year. Earlier, Min Zin, director of a Myanmar-focused think tank, was arrested in Kunming. These detentions occur amid delicate U.S.-China relations, with both countries aiming for improved relations after years of disputes concerning trade, security, and technology. President Donald Trump has invited Chinese President Xi Jinping to visit Washington in September, after Trump’s visit to Beijing in May.
The Chinese Embassy in Washington, D.C., and the U.S. State Department have been contacted for comments via email, according to Newsweek.
Trump Administration’s Quiet Diplomacy
Born in China, Chen became an American citizen in 2011 and resides in Boston, Massachusetts. He holds the unique status of being the only American in China formally designated as ‘wrongfully detained.’ This determination was made by Secretary of State Marco Rubio on March 19.
Chen has never possessed a U.S. government security clearance. His wife, Rong, states that the espionage accusation is ‘both wrong and inconsistent with the public and collaborative nature of the work that he has done.’ This statement was shared with Newsweek by Eric Lebson, head of the hostage advocacy group Global Reach.
The Trump administration has reportedly avoided making Chen’s status a focus of public concern, hoping that discretion might lead to his release. Trump raised the issue of Chen’s detention during discussions with Xi in Beijing.
Rong has opted to publicly address the situation following the lack of response from Chinese officials to Trump’s appeal. She fears a predetermined trial outcome, stating, ‘I believe they will convict him no matter what, and the trial will be behind closed doors.’ Espionage convictions in China can result in life imprisonment or the death penalty.
Chen’s Research Under Scrutiny
At the heart of Chen’s detention is his research on seismic signatures linked to North Korea’s nuclear tests. His work includes a December 2020 study for the State Department that examined seismic data from all six nuclear explosions conducted by North Korea between 2006 and 2017, which incorporated data collected in China. Chinese authorities have questioned Chen over 100 times about his expertise, according to Rong.
China, along with the United States and Russia, signed the 1996 Comprehensive Nuclear-Test-Ban Treaty, which bans nuclear weapon test explosions in any environment. None of these countries have ratified the treaty, but they have observed voluntary bans on explosive nuclear testing. However, senior U.S. State Department officials suggested in February that China covertly conducted a nuclear test in 2020, employing decoupling to reduce detection of underground tests. This test reportedly caused a seismic event at Lop Nur, a nuclear testing site in the Xinjiang Uyghur Autonomous Region.
