Since the 18th Party Congress convened in November 2012, China has undertaken a wide-ranging campaign against corruption. The campaign has gone on longer, cut deeper, and affected more people than anyone might have imagined two years ago. The course of the campaign has exposed in considerable depth many of the ills of political life in China. Although it seems intended to break up many of the “small circles” that pervade China’s political life, there is no question that the campaign has focused particular attention on the networks around Zhou Yongkang, the former head of China’s security forces, and Ling Jihua, the former head of the General Office. China’s leadership has promised the campaign will continue, so there are likely to be more surprises; perhaps one or more new “tigers” will be exposed.
