In 2006, which China named the "Year of Africa," it quadrupled its investment commitments to infrastructure in Sub-Saharan Africa, to more than billion. In 2007 China committed another .5 billion. Such funds could make a significant contribution toward meeting Africa's infrastructure investment needs. In the power sector, where Africa faces some of its largest gaps, China is investing .3 billion, including .3 billion in projects that, if completed, will increase the region's hydro generation capacity by 30 percent. China's growing role in Africa has generated much discussion. A new study seeks to add concrete numbers and solid analysis.
