Travelling across three continents, Justin Rowlatt investigates the spread of Chinese influence around the planet and asks what the world will be like if China overtakes America as the world's economic superpower. In the first of two films, he embarks on a journey across Southern Africa to chart the extraordinary phenomenon of Chinese migration to Africa, and the huge influence of China on the development of the continent.
