The oldest Confucius Institute in the United States is closing. In a letter to students and faculty and staff members at the University of Maryland at College Park, President Wallace D. Loh said the 15-year-old Chinese language and cultural center would shut down because of 2018 legislation that made colleges with the institutes, which are supported by the Chinese government, ineligible for certain Defense Department funding. Maryland is among nearly two dozen American colleges to close their Confucius Institutes in the last two years. And it’s the second in little more than a week —– the University of Missouri also will shutter its center. Colleges have faced pressure over Confucius Institutes from lawmakers who say the agreements lack transparency and amount to Chinese-government propaganda on American campuses. In his letter, Loh said Maryland remained committed to education and scholarship in Chinese language and culture.
