That's an excellent question.
One of the things that needs a lot of focus is agriculture. South Sudan is one of the most fertile countries in the region. There is tremendous potential for agriculture, both in South Sudan to feed South Sudan, but also as trade and an ability to feed other parts of the region. There is a tremendous untapped potential there, and it is being impacted by conflict, insecurity, lack of access to education and lack of ability to stay on your land. If you're getting displaced from your land every six months, then you're not going to actually be able to build that agriculture.
You also have tremendous tourism opportunities. The Nile goes through South Sudan. Some of the largest herds of wildebeest in the world go through South Sudan as well. I managed to see a little bit of it while I was there, so there are tourism opportunities as well, but agriculture's a key.
