A China-born American seismologist is detained in China without trial for nearly two years, the person’s family says, according to multiple outlets. The family’s account is supported by an advocacy group advising them, which says the detention has continued with no court proceedings. The reports describe the case as raising questions about due process and access to information about the seismologist’s status. One outlet notes the development comes amid broader diplomatic attention: it frames the matter as one that U.S. President Donald Trump has raised with Chinese leader Xi Jinping, and it also highlights that Xi is expected to visit the United States in the coming months. The articles do not provide additional agreed details such as the scientist’s identity, the specific basis for detention, or the legal steps—if any—taken in China. Overall, the reporting focuses on the family’s claim that the scientist has been held for close to two years without trial, and on the case’s connection to high-level U.S.-China engagement.
