The paper assesses the role played by ASEAN in the management and resolution of disputes between its member-states in the Southeast Asian region. The ASEAN approach to conflict management and the context in which it has developed is presented. The achievements and challenges that ASEAN has faced and is still facing in the field of conflict management are identified. ASEAN’s contribution to conflict management in the Southeast Asian region is recognised although the nature of the contribution and the role played by the Association is debated. ASEAN’s model and approach to conflict and dispute management and the possible impact of the approach on the conflict situation in the Southeast Asian region are examined from three main dimensions: the core elements of the approach, the role played by the Association in terms of conflict management, and the possible impact of the ASEAN approach in managing disputes among its member-states. The possible impact of recent developments within ASEAN – the ASEAN Charter in particular – is analysed in assessing the role that the Association can play in promoting conflict management.
