This policy brief identifies four crucial dimensions to power-sharing agreements, and discusses the extent to which the Revitalized Agreement on the Resolution of the Conflict in the Republic of South Sudan (R-ARCSS) agreed upon on August 28, 2018 accommodates these dimensions. The R ARCSS, despite considering all four dimensions of power-sharing, lacks clarity on crucial elements, is deficient in terms of the provisions for third-party enforcers, and is vulnerable to failure due to the ethnic nature of the conflict. Deepening of the various powersharing dimensions, making allowance for a third-party enforcer, and addressing underlying political and ethnic cleavages are some of the steps that the Transitional Government of South Sudan and the international community can take to strengthen the implementation of the R-ARCSS.
