South Sudan is a landlocked state in East-Central Africa whose capital is Juba. The country is bordered by Sudan to the north, Ethiopia to the east, Kenya, Uganda and the Democratic Republic of the Congo to the south, as well as the Central African Republic to the west. South Sudan is also the youngest country in the world. Since gaining independence from Sudan in 2011, it has experienced ongoing instability, including civil war and famine. Amid the nascent country's many problems, South Sudan's main challenge is the management of its various ethnic groups. Indeed, much of the nation's civil war has stemmed from battles for power between its major ethnic groups. The country's lack of sea access has also restricted its economic prospects because of the associated high cost of imports and exports. As it is, transport links throughout Central and East Africa are poor, but South Sudan's logistical problems are naturally exacerbated by its instability and violence. Still, South Sudan does boast proven oil reserves – something that has driven foreign interest in the area for decades. Nevertheless, the unlikelihood that hostilities will end anytime soon, coupled with the further erosion of Juba's control over territory, has greatly complicated investment in the oil industry. Accordingly, there appears little chance that South Sudan will rectify its deep structural deficiencies and end the fighting among its major ethnic groups anytime soon.
