“Since 2000, nearly 30 developing countries have grown by 6 percent or more a year. Developing countries are now the engine driving the global economy, accounting for around two-thirds of global growth

They have stable governments that pursue prudent economic policies, provide essential infrastructure and services, and take a long-term perspective. They use the opportunities provided by global markets and they have a dynamic and competitive private sector”
