China has taken the lead in building up infrastructure in some of the world's poorest regions in Sub-Saharan Africa, the World Bank said in a new report released Thursday, according to dpa. India and some Middle Eastern countries have also contributed to a record number of infrastructure projects being financed in southern Africa, an area of the globe that has long been neglected by international investors. In a growing sign of cooperation between developing countries, the World Bank said that emerging economies' investment in Africa had jumped from an average 1 billion dollars per year before 2004, to 8 billion dollars in 2006 and 5 billion dollars in 2007. Much of Africa's infrastructure remains woefully inadequate and is cutting the continent's growth rate by an average of 1 per cent per year, due to extra transport costs and a lack of power generation. The new influx of funds could help address those inefficiencies, the bank's report said. But China has also gained from the partnership, acquiring 22 billion dollars worth of natural resource exports from Sub-Saharan Africa in 2006, up from only 3 billion dollars in 2001. Of those exports, 80 per cent is petroleum to feed China's surging energy needs. The complementary demands have created a win-win situation for both sides, according to Vivien Foster, a World Bank economist and lead author of the report. "China's growing demand for natural resources is matched by Africa's significant and often under-developed oil and mineral reserves," Foster said. "Africa's urgent need for infrastructure is matched by China's globally competitive construction industry."
