After unprecedented Paris summit, president will promote prosperity during two Africa stops

The world is expected to learn how its second-largest economy will deal with climate change, and how it will help bring prosperity to the least-developed continent - all with a France-Africa visit by President Xi Jinping that starts on Sunday.

For the first time, the Chinese president will attend and address the opening ceremony of the UN climate conference, joining an unprecedented gathering of world leaders to push for a pact to curb global warming.
