Beijing renewed grievances with Washington on Friday over what it described as systemic bias against Chinese scientists, following the reported suicide of a postdoctoral researcher living in the United States.

During the Chinese Foreign Ministry’s regular press conference, spokesperson Lin Jian responded to a query about the researcher, who state media said had died one day after being interrogated by U.S. law enforcement.

“We are deeply saddened by this tragedy and have made solemn representations to the United States,” Lin said. He added that Chinese diplomatic missions had been in contact with the family of the deceased and were assisting with follow‑up arrangements.
