The rebound of oil prices and the stabilization of regional political security are two major factors that stimulated the economic growth of the area of West Asia and North Africa in 2016.The economic growth momentum of West Asia and North Africa will be weakened in 2017，with downward pressure mainly from intensified geopolitical tensions and conflict，oil prices lower than expected，and negative effects of fiscal consolidation on public expenditure. The economic growth of Sub-Saharan Africa had experienced a sharp slowdown in 2016，as the result of weak commodity prices，poor performance of Nigeria and South Africa. Sub-Saharan Africa’s economic growth in 2017 will be much stronger than that in 2016. The main favorable factors include rebounded global commodity prices，improved performance of Angola and Nigeria，and better domestic economies conditions in some countries as result of structural reforms. The main risks come from policy uncertainty of some developed economies，commodity prices lower than expected，and blocked structural reform.
