Has China’s process of reform gone into reverse?

The Chinese Communist Party guides the thinking of the masses through slogans. Some of these are written in huge letters on walls around the country. They are studied by party members, who try to figure out how society should respond. One of the most famous slogans is "reform and opening up." It has been in constant use since the late 1970s and although its meaning has changed significantly since then, Sinologists believe it remains a guiding principle for Xi Jinping. In this podcast, presenter Duncan Bartlett asks Professor Steve Tsang, Director of the SOAS China Institute, about the meaning of the phrase and its significance.
