HONG KONG (MarketWatch) — China is launching a nationwide investigation on the use of foreign textbooks at Chinese universities and colleges, following a previous government pledge to reject texts spreading “Western values” at the nation’s centers of higher education.

Several universities in Beijing received notifications last week from the Ministry of Education, requiring instructors to fill out investigation forms about the presence and use of “foreign textbooks in original languages” in class, the government-run Beijing Youth Daily reported Tuesday.
