Elite corruption may have a significant role in ending conflicts and shaping post-conflict development. This article enquires into the legitimacy accorded to such corruption. It reviews literature on post-conflict Cambodia, seeking evidence that academic commentaries, public opinion or elites themselves regard elite corruption as a legitimate Machiavellian tool for achieving other ends. Corruption has been an element of the style of government adopted by the dominant party in Cambodia, shaping both the achievement of peace and the uneven economic development that followed. Academic commentaries provide some implicit and explicit legitimation of corruption as a means to secure peace and to resist neoliberal policy settings by affording government discretionary resources and power. Meanwhile, public dissatisfaction with elite corruption appears to the most likely source of renewed violent conflict in Cambodia. How elite actors rationalise and legitimise corrupt behaviour remains poorly understood, and is deserving of more attention.
