"This Policy & Practice Brief focuses on the challenges facing the two Sudans post separation. 17 October marks 100 days since the fracturing of the Sudan. It is, therefore, an opportune moment for reflection on the state of affairs as the two states move into uncertain futures. The date also offers a chance to assess the trajectories of the two countries as they chart separate, but linked destinies. While assessing the past 100 days, one should be cognisant that the next three years will most likely set the tone for not only the internal dynamics but also the cross-border relations between the two states. This brief highlights the fact that much of the current tension between and within the two states can be seen as a manifestation or projection of internal political dynamics and power struggles. As a result, policy interventions need to be designed to have a dual focus, namely the national capitals and the actual sites of conflict."
