And so the file of the border between Sudan and Abyssinia officially ended on the Suruq.
The surveying and demarcation of these borders remained. Britain appointed two surveyors, Captain Engineer Austin, who was tasked with surveying the southern part of the border, and Major Engineer Goin, who was tasked with surveying the part located between the Blue Nile and the Sobat.
The British representative in Addis Ababa, Harrington, reached an agreement with Menelik. The agreement, in addition to codifying the borders, was signed on May 15, 1902. It included a clause for the formation of a joint committee to establish border markers. However, Menelik did not respond to the decision to form the committee, so Goin placed the markers alone. This led to disputes over these borders after the middle of the twentieth century. The agreement of 1902 also included border-related issues: 1. Menelik pledged not to build any works on the Blue Nile, Lake Tana, or the Sobat River that would affect the Nile waters.
2. The British government and the government of Sudan were granted a piece of land adjacent to Itang on the Sobat (Baro) River, which the government of Sudan would lease for the purpose of administering it as a commercial station and occupying it for the duration of Britain's presence in Sudan.
3. Abyssinia did not grant Britain and the government of Sudan the right to construct a railway line between Sudan and Uganda passing through its territories. The most important observations regarding the demarcation of the borders in the Baro sector were that it divided the lands inhabited by the Nuwer and Anwak tribes, two tribes that used to cross the borders in search of pasture and hunting. This led in later periods to administrative and security problems that constituted a constant headache for the governments of Sudan and Britain. Several attempts were made later to rectify this situation, but they led to disputes and claims regarding its other borders with Somalia and Kenya. As for the southern part of the border, it was not demarcated until 1914. It was then located within the borders of Uganda. After the demarcation of the borders between Sudan and Uganda in 1907, Sudan became automatically bound by a treaty in 1914.
