This chapter examines how justice norms and crime control models travel around the world, and the Global South’s role in global, supranational, and transnational criminology. We argue that the Global South has exercised more agency than it has typically been credited with in contributing to, initiating, and contesting international justice and transnational crime control. Internationally, global justice norms and policies have been primarily shaped by Global North countries, yet this chapter shows how Global South countries have engaged in contestation, struggle, and alternative worldmaking in the development of these international justice regimes. Transnationally, the travel of crime control models has tended to occur through the foreign policies of Global North countries, yet the chapter problematizes these processes of “diffusion” and “translation” and highlights the contested nature of Global North-South interactions. Finally, we reflect on the implications for global criminology of the Global South’s changing role amid shifting global power dynamics, as the liberal global order fragments and gives way to multipolarity.
