Corporate actors have been under increasing scrutiny by the international community for the adverse impacts caused by way of involvement in the human rights abuses of third actors when conducting business in vulnerable areas with poor governance structures and weak legal systems. At the same time, impunity of corporate actors involved in abuses has been the recurrent pattern. Against this background, the notion of corporate complicity has increasingly been resorted to by lawyers and advocates of business and human rights movements to portray the corporate position vis-à-vis the human rights abuses of third actors and to seek a greater degree of corporate accountability for violations of human rights standards.Complicity in human rights abuses by corporate actors has proved to be a major force behind escalation of conflict by way of exacerbation of the conditions leading to violence. Addressing ways to tackle corporate complicity and ensure effective corporate accountability for complicity, therefore, appears significant in terms of prevention of renewed violence and promotion of reconciliation and peace for countries transitioning from periods of conflict or authoritarian rule. In light of this, the present thesis investigates, through the lenses of international law, how human rights practices adopted by corporate actors operating in fragile areas and accountability for corporate-related human rights violations are relevant tools to the process of promoting peace in its negative and positive dimensions.
