Dr. Youlin Chen is an American seismologist and academic from Boston, Massachusetts, who conducted research on U.S. government-funded projects. In October 2024, Dr. Chen traveled to the People’s Republic of China (PRC) to visit family in the country. He was preparing to return home when, on November 5, 2024, he was arrested at Beijing Capital International Airport by agents of the Beijing State Security Bureau. The agents accused him of espionage because of research he had conducted for the U.S. government—unfounded allegations against an American researcher.
Secretary of State Marco Rubio designated Dr. Chen as wrongfully detained in March 2026.
