An American scientist who has studied underground nuclear tests has been detained in China for greater than 18 months on spying costs, in line with his supporters and a US lawmaker.
Youlin Chen, a seismologist, has been “wrongfully detained” since November 2024, US Senator Edward Markey stated in an announcement Tuesday.
President Donald Trump raised Chen’s detention and requested for his freedom throughout a gathering with Chinese chief Xi Jinping in Beijing in May, in line with Global Reach, a US non-profit that has been working with Chen’s household on his case.
Chen, who was dwelling in Boston and has a college-age son, is the one American at the moment held in China designated as wrongfully detained, the non-profit stated.
The case provides one other level of friction between the US and China as they attempt to stabilize ties. Its revelation comes weeks after China confirmed the arrest of one other US scholar, Min Zin, who it stated is “suspected of spying and endangering Chinese national security.”
Global Reach stated there are suspicions that Chen’s detention is linked to China’s current growth of its nuclear capabilities, together with finishing up an alleged underground nuclear check in 2020. Beijing denies this check.
Chen’s work focuses on utilizing seismological knowledge to enhance strategies to establish and monitor nuclear tests. It has included analysis into North Korea’s underground nuclear testing.
Chen’s analysis has been funded by the US State Department and US Air Force Research Laboratory.
In December 2020, he authored a technical report that used regional seismic knowledge recorded throughout Asia, together with knowledge from stations in China, to enhance strategies for nuclear-test monitoring and yield estimation, in line with Global Reach.
A subsequent 2024 research that he authored was additionally funded by the US Air Force Research Laboratory and the US Department of State and “further reinforces Chen’s expertise in the seismic monitoring and detection of underground nuclear tests,” the group stated.
He was detained on the airport after visiting his dad and mom in Beijing, in line with Kieran Ramsey, chief investigative officer at Global Reach.
A State Department spokesperson instructed NCS that the US has raised Chen’s case immediately with Chinese officers and referred to as for his instant launch.
When requested by NCS whether or not the case was raised by Trump throughout his assembly with Xi, a White House official stated that “President Trump has been clear that he wants every American detained abroad to return home.”

Noting that her husband “works transparently with Chinese colleagues on scientific collaboration,” she added: “He is doing precisely the kind of people-to-people engagement that the Chinese government says it wants.”
US embassy officers have visited Chen a number of instances, however Chinese officers are all the time current, stopping him from talking freely, Rong instructed Reuters in an interview. She retained a Chinese lawyer, however he was allowed to see Chen solely after the scientist had been detained for greater than 13 months.
Chinese officers have interrogated her husband greater than 100 instances about his work on the seismographic signatures of North Korean nuclear tests, she stated.
