History of bilateral relations
Together with the US, Switzerland facilitated a ceasefire in the Nuba Mountains known as the Bürgenstock Agreement in 2002. It then actively participated in the negotiations and implementation of the Comprehensive Peace Agreement for Sudan in 2005, which served as the basis for the South Sudanese independence referendum in 2011.
Together with the international community, Switzerland recognised South Sudan as a nation in 2011. In 2012, South Sudan opened a permanent representation in Geneva, which is also accredited as an embassy in Switzerland. Switzerland has had a cooperation office in Juba since 2006.
Switzerland and South Sudan have not yet concluded any bilateral agreements.
