Economic growth of West Asia and North Africa has slowed down sharply. The economic growth rate in 2019 is even less than one third of the world average，and the growth trend is extremely weak. The main reasons for the poor economic growth trend of West Asia and North Africa are geopolitical factors and oil limit agreements. Growth of Sub-saharan Africa has been relatively stable，but it has been accompanied by a widening current account deficit，rising government debt as of percentage of GDP，and weak economic activity in major sub-regional economies such as Nigeria，South Africa，and Angola. Looking ahead，with the relative improvement of the world economic situation，the economic growth rate of West Asia and Africa will be improved. It is expected that the economic growth rate of West Asia and North Africa will reach 2.9% and that of Sub-saharan Africa will reach 3.6% in 2020. Even so，downside risks to growth of West Asia and Africa have increased.
