Currently detained

Massachussetts


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.

Limited Contact

Since his arrest, the US embassy personnel have been allowed to visit Dr, Chen, but are not allowed to discuss his case with him. His family has not been allowed any direct contact with Youlin since his arrest.

Health Concerns

Dr. Chen’s health remains a concern. He suffers from diabetes, high blood pressure, and high cholesterol—conditions that require consistent medication and medical monitoring. He needs reliable access to treatment and care that may not be adequately available while he is unjustly incarcerated.

Wrongfully Detained

Dr. Chen and his family are suffering. He is innocent and is being used as a tool for political leverage by the PRC. Furthermore, his continued wrongful detention underscores the threat that the PRC poses to American researchers. Responsible countries do not detain academics because of their research. Given Dr. Chen’s designation as “wrongfully detained,” it is clear that his case has the attention of President Trump and senior leaders within the U.S. government. As long as Dr. Chen remains wrongfully detained by the Chinese government, his unjust imprisonment will continue to be a source of tension between our countries.
