U.S. Treasury Secretary Janet Yellen will kick off a year of visits by top U.S. officials to Africa on Friday aiming to firm up U.S.-Africa ties after decades in which China has dominated investment across the continent.
In a speech to be delivered at a business event in Senegal's capital Dakar, the first leg of her three-country trip, Yellen will map out the U.S. vision for strengthening African relations, eyeing the massive economic opportunities created by its demographic boom.
