"In Canada not everyone will agree with Harper's interpretation of what Vimy means for today. We have a multiplicity of views about the past and its significance for the present. In China, by contrast, the Communist Party does its best to ensure that the public gets only one version of history. When my book on Nixon’s trip to China in 1972 came out, Chinese publishers showed an interest in translating it. There would, however, have to be a few small changes. Mention of the Cultural Revolution and of Mao’s often scandalous private life would have to go. (The book has not been published in China.) Although the Communist Party has repudiated most of Mao’s policies, it still holds him up as the father of the Communist Revolution. To question him would be to undermine the Party’s own authority to rule China."
