The Center for Global Development think tank said a review of 535 public-private infrastructure deals funded in the region in those years showed that China's investments dwarfed those of other governments and multilateral development banks.
Nancy Lee, lead author of the paper and a senior policy fellow at the center, said overall public funding for projects in sub-Saharan Africa remained stuck at around $9 billion, well short of what the region needs for roads, dams and bridges.
"There is a lot of criticism of China," she said. "But if Western governments want to boost productive and sustainable investments to meaningful levels, they need to deploy their own development banks and press the multilateral development banks to make these investments a priority."
