“Strike hard” anti-crime campaigns, “harmonious justice” and “stability maintenance” are the three key politically inspired agendas of crime control and punishment in 21st-century China. This paper is a study of how discourse has helped to package these agendas and to mobilize politico-legal functionaries into action. It examines discourse in the first weeks of the 2014 “people's war on terror” and the agendas of “harmonious justice” and “stability maintenance” in the Hu Jintao era. It finds that each has been rationalized and shaped by an understanding of the utility of punishment based on Mao's utilitarian dialectics. The political virtuosity of Mao's dialectics is that it can be adapted to suit any political situation. In understanding how Mao connects with criminal justice in China today, this paper identifies what is the “political” in “politico-legal” discourse in the fight against crime in the 21st century.
