Shanghai was one of the first Chinese ports to be opened to Western trade, and it long dominated the nation’s commerce. Since the communist victory in 1949, however, it has become an industrial giant whose products supply China’s growing domestic demands. The city has also undergone extensive physical changes with the establishment of industrial suburbs and housing complexes, the improvement of public works, and the provision of parks and other recreational facilities. Shanghai has attempted to eradicate the economic and psychological legacies of its exploited past through physical and social transformation to support its major role in the modernization of China.
