Between January 2003 and July 2015 the survey identified 383 FDI projects, which accounted for a total capital investment of $55 billion. South Africa received one-fifth of the projects. Other leading recipients were Nigeria, Kenya, Egypt, Tanzania, and Ethiopia. Most of the projects were in the field of financial services although most of the capital went into coal, oil, and natural gas projects. If this report is accurate, then India's FDI in Africa far exceeds China's FDI in Africa based on official Chinese statistics.
