In December 2016, to mark the twenty-fifth anniversary of the 1991 Paris Peace Agreement that ended the decade-long war between Cambodia and Vietnam, USIP hosted a conference to examine the implementation of that agreement and how the decisions made in the past have affected increasing political unrest in the country. Panelists included several key actors from that historic agreement and Cambodia’s human rights community. Since then, the political situation in Cambodia has become tense as the government has sought to marginalize opposition groups. This Brief draws on the lessons from that conference and offers recommendations on priorities for the international community in advance of the upcoming national elections in Cambodia.
