The South Sudan issue is one of the most dangerous ethnic issues on the African continent, which has sparked a civil war between the north and the south. Although the issue was settled under the 2005 peace agreement, which resulted in the secession of the South in 2011 and the formation of the state of South Sudan, many of the outstanding political, security, and economic issues between Sudan and South Sudan were not finally resolved, which is what this research aims to focus on. Through a descriptive and prospective approach, it became clear that these pending issues have left the door open to several possibilities for the future of relation between the two countries, determined by the possibility of returning to war, establishing cooperative relations, or returning to unity on a federal basis. The research was divided into three sections, in addition to an introduction and a conclusion that contained the most important findings. The first section addressed the nature of the South Sudan issue and its developments. The second explored the outstanding issues between Sudan and South Sudan. The third focused on the future prospects for the relationship between Sudan and South Sudan.
