This paper analyzes how human trafficking policies diffused in the post-Soviet region. By adapting the diffusion of innovation framework to fit the international context, I examine whether human trafficking adoptions in the post-Soviet region were due to internal determinants and/or diffusion effects. A comparison of Russia, Latvia, and Ukraine found that internal determinants such as state commitment to human trafficking policy and interest group strength were more important to policy adoption than external pressures from the international community while state capacity and bureaucratic restructuring impeded policy adoption. I argue that policymaking, even in authoritarian regimes, is more nuanced than blind compliance with international treaties and shows that interest groups and policy entrepreneurs work within the constraints of national policymaking to adopt human trafficking policies. © 2017 The Editor, Journal of Comparative Policy Analysis: Research and Practice.
