To understand today's headlines about China's approach to issues such as trade, foreign policy or internet censorship, turn to its past. The country is perhaps more aware of its own history than any other major society on earth. That remembering is certainly partial - events like Mao's Cultural Revolution are still very difficult to discuss within China itself. But it is striking how many echoes of the past can be found in its present. China remembers a time when it was forced to trade against its will.
