Ethiopia–South Sudan border

The Ethiopia–South Sudan border stretches 1,114 kilometers from the tripoint of Sudan in the northern beginning of the Illemi Triangle disputed area between Kenya and South Sudan. The border was created by the sphere of influence of British colonial administration in May 1902, creating Anglo-Egyptian Sudan. It shares projecting border via Gambela Region of Ethiopia with 543 miles. Livelihood in this area often subjected exclusion from political, economic and other development associations as there is prevalence of armed insurgent groups like Gambela People's Liberation Movement, which engage in illicit trade, child abduction, cattle rustling and arm smuggling.

Since South Sudan gained independence in 2011, the most recent negotiation agreement was signed in Addis Ababa on 27 September 2012.
