I call your attention to a new study by the Global Health Strategies Initiatives (GHSi) titled Shifting Paradigm: How the BRICS are Reshaping Global Health and Development. You can access the report here. GHSi is an international nonprofit organization that advocates for improved access to health technologies in developing countries.
The report covers foreign aid, health assistance and their implications for global health with an analysis of the BRICS: Brazil, Russia, India, China and South Africa. While all five countries have been engaged in foreign assistance for decades, the report finds that the size and scope of their efforts have grown rapidly along with their economies. Although G-7 donors still provide far more total assistance, the report estimates that the average annual growth in the BRICS' foreign assistance spending between 2005 and 2010 was more than ten times higher than that of the G-7.
