[Photo/Agencies] Sources told China Daily that Washington has kept playing a hypocritical, double-faced role in China-US education exchanges this year, as it encouraged US universities to enroll more Chinese students while failing visa applications from over 500 Chinese students who had obtained offers to pursue postgraduate study in STEM majors. About a quarter of these students have won US scholarships, and the majority submitted visa applications after the new US administration took office, sources familiar with the matter told China Daily, on the condition of anonymity.
