Thanks for your enquiry. At the end of 2011 ISSAT supported a feasibility study undertaken by the Norwegians. The aim of the study was to see whether and how Norway could best support reform of the defence sector in the Republic of South Sudan by building capacity in the Ministry of Defence. This study was followed up by a more detailed fact finding process undertaken by the Norwegian MoD. I am not sure if a decision was reached on whether or not to embark on a Norwegian engagement before the current outbreak of violence in South Sudan, which has effectively resulted in a halt in international development (and SSR) support to the country.
To my knowledge, supporting defence sector reform is the only SSR focus for Norway in South Sudan.
