Jeffrey Sachs, Ngozi Okonjo-Iweala and Mohamed El-Erian discuss the big economic and political trends and risks to watch out for in the year ahead.

Economics Professor Jeffrey Sachs of Columbia University explains his pointed views on the US-China spat over Chinese tech firm Huawei, for which he recently received a barrage of criticism on social media. Former Nigerian finance minister and World Bank managing director Ngozi Okonjo-Iweala relays how Africans have been left astonished and consternated by Brexit. And bond investor supremo Mohamed El-Erian of Allianz and Pimco says the global economy and financial markets are likely to get tougher over the next 12 months, although nowhere near as bad as 2008.

The discussion is hosted by Manuela Saragosa. The producer is Laurence Knight.
