China detains US scientist who studied Nuclear weapons

‎China has detained a US seismologist who tracks nuclear tests for nearly two years on espionage charges, his family says.


‎Chen Youlin, 54, was arrested in November 2024 during a trip to Beijing to visit family, according to hostage advocacy group Global Reach. The family decided to speak out after they saw no sign of Beijing freeing Chen.

‎His wife Rong Yufang, also a seismologist, said Chen worked closely with Chinese colleagues, and the allegations are “both wrong and inconsistent with the public and collaborative nature of the work that he has done”.

‎His published work centres on North Korea, a close friend of China and long sanctioned for its nuclear weapons programme and underground tests.

‎It is unclear if and how Chen’s work touched on Beijing’s nuclear programme. US intelligence suggests that China is developing a new arsenal and has conducted secret tests, which Beijing denies.

‎When asked about the case at a daily press briefing on Tuesday, China’s foreign ministry said its “judicial authorities handle cases in accordance with the law”.

‎”There is no such thing as so-called wrongful detention,” the ministry’s spokesman Lin Jian said. In China, espionage convictions can lead to life imprisonment or death.

‎Chen is currently the only US citizen designated as “wrongfully detained”.

‎”I have not been able to speak with my husband for over 600 days and am concerned for his health and well-being,” Rong said in a statement through Global Reach.

‎In an interview with Reuters, she said Chinese authorities interrogated her husband more than 100 times on his work and that he wasn’t allowed to see a lawyer for the first 13 months of his detention
