Rwanda is one of Africa's most remarkable recovery stories, but it is coming up against limits to its growth. "I see Rwanda as a rocket," says Moustapha Soumaré, United Nations resident co-ordinator in Rwanda. "But the boosters are not rocket boosters."

The main constraints are a scarcity of qualified and skilled people, a narrow agricultural base, shortage of energy supply to support its aspirations as a modern service economy, and dependence on external financial support.
