I want to know the answer to the following question:
What has been the change in foreign exhange reserves since 2011?
All the background I'm provided with is that "Foreign direct investment (FDI) in Egypt increased considerably before the removal of Hosni Mubarak, exceeding $6 billion in 2006, due to economic liberalisation and privatisation measures taken by minister of investment Mahmoud Mohieddin.[citation needed]". Is that enough to answer the question?
