Chinese President Xi Jinping said Monday that Chinese funds are not for "vanity projects" in Africa but are to build infrastructure that can remove bottlenecks in the continent's development.

Speaking at a business forum ahead of the start of a once-every-three-years China-Africa summit, Xi said: "Resources for our cooperation are not to be spent on any vanity projects, but in places where they count the most."

"Inadequate infrastructure is believed to be the biggest bottleneck to Africa's development," he added.
