Originally perceived as benign cultural bodies, not unlike the Goethe Institute run by the German government or the Alliance Française, the Confucius Institutes were welcomed by many universities because they provided cheap or even free Chinese-language classes and professors. Over time, the institutes aroused suspicion by policing Chinese students at American universities, seeking to block public discussions of Tibet or Taiwan, and in some cases altering the teaching of Chinese history and politics to suit Chinese narratives.
