The Canadian Association of University Teachers this week called for colleges and universities in Canada to sever ties to Confucius Institutes, which have been set up at many Canadian (and American) campuses with support from the Chinese government. Supporters say that the institutes are a valuable way to expose more students outside China to Chinese history and culture. But critics say that the institutes present an oversimplified and positive image of China and that universities that want the house institutes may feel pressure to avoid certain topics. A statement from James Turk, executive director of the Canadian faculty group, said: “Confucius Institutes are essentially political arms of the Chinese government. They restrict the free discussion of topics Chinese authorities deem controversial and should have no place on our campuses."
