Family says US seismologist has been detained in China for nearly 2 years with no trial

A China-born American seismologist, Youlin Chen, has been detained in China for nearly two years without a trial, according to an advocacy group. His family, advised by Global Reach, revealed the situation as Chinese officials showed no sign of releasing him, despite President Trump raising the case during a meeting with President Xi Jinping. Chen, charged with espionage, has worked as a U.S. government contractor analyzing seismological data.
