One of the key policy domains where a substantial policy breakthrough was made under the National Unity Government (2015-2019) in Sri Lanka was national reconciliation and post-war peacebuilding. National reconciliation in the post-war context constitutes to be a wider-deck process with short-term and long-term priorities. Since the end of the civil war in 2009, Sri Lanka seemed standing at a crossroads, bewildered as to the direction it should take regarding post-war peacebuilding and the realization of ethnic cohesion and inclusive development. The approach of NUG to strengthen and implement policies in the field of reconciliation was based on four broad pillars: Truth-seeking; Right to Justice; Reparation; and Non-recurrence. Given the attention to some policy implementations, this chapter focuses on how the NUG has taken certain rigorous measures to meet international demands on Sri Lanka’s reconciliation process, as well as some of the key achievements and challenges.
