A Justice Department official said they were a different group to those mentioned by the State Department in September, when it said the United States had revoked visas for more than 1,000 Chinese nationals under a presidential measure denying entry to students and researchers deemed security risks.
The official said the researchers Demers referred to, who U.S. authorities believed were affiliated with China's People's Liberation Army, fled the United States after the FBI conducted interviews in more than 20 cities and the State Department closed China’s Houston consulate in July.
"Only the Chinese have the resources and ability and will" to engage in the breadth of foreign influence activity that U.S. agencies have seen in recent years, Demers said.
