Building up closer bonds

Despite visa curbs on Chinese students, Yale University president is calling for deeper US-China education ties, Chen Weihua reports from Davos, Switzerland.

Peter Salovey, Yale University president, says he is proud of the Ivy League institution's association with China and wants to further strengthen ties.

His comments come amid US government's tightening of visa restrictions for Chinese students and the call by some US politicians for more curbs on Chinese seeking to study in the United States.
