Such investment is essential in a world in which net private capital flows to developing countries outstrip official development assistance by a margin of ten to one. If this is to be a turning point for Africa, rather than another false dawn, this summer must be the start of a prolonged effort to stimulate private-sector engagement.
如今，流向私人净资本流是官方发展援助的十倍，在这样的背景下，这类投资十分关键。如果这成为非洲的反转点而不是又一次假反弹，那么今年夏天必然是刺激私人部门参与的长期努力的起点。
