Like so much else under Heaven, repression in China has often seemed to go in cycles. Every now and then it has suited the country’s leaders to relax their steely grip on the country and allow a modicum of political liberty. Freer criticism in the media has helped give the party a veneer of credibility. Lip-service to the law and due process has won plaudits overseas and boosted the economy at home. So a thaw would set in for a while, a “Beijing spring”. A freeze would always follow. But, until lately, in each new cycle the springs were seeming warmer and the freezes not quite so harsh. When the country was starting to liberalise, Westerners justified doing business with China on just such grounds. More economic openness would surely lead to more openness of other kinds.
