6. Sudan
Nominal GDP: $93.729 billion
When it comes to Sudan, certain segments are highly developed, thus positively affecting its economic development, while on the other side there are still some obstacles and horrible structural issues that need to be resolved as soon as possible. The most important aspect is definitely the petroleum sector since it is responsible for the economic stability and foreign exchange. On the other side, foreign investors hesitate a lot to invest in Sudan, due to continuous conflicts with rebels. There is also the issue of the unstable government, corruption, and weak legal system. The annual growth measured in 2013 was 3.6%, and besides the petroleum, mining and agriculture are also very important in this regard, being the reason why the country is on the list of most economically developed countries in Africa.
