Dr Ngozi Okonjo-Iweala, head of the WTO: What is going on in the Middle East will have a significant impact on trade

“The global economy is full of uncertainty… business doesn't do that well with uncertainty. So with respect to trade… what is going on in the Middle East will have a significant impact on trade” Ben Thompson speaks to Dr Ngozi Okonjo-Iweala Director General of the World Trade Organisation. The global trade system - embodied by the WTO - is supposed to bring countries together by setting and enforcing the rules for them to sell goods and services to each other as well as resolve trade disputes. This week in Cameroon a WTO ministerial Conference is taking place against the backdrop of war in the Middle East and unprecedented challenges to the established world trading system. The war, President Trump's tariffs and a growing urge for independence are all impacting the way goods and services flow across borders. In this interview Dr Okonjo-Iweala discusses the restrictions coming into force and their impact on global trade. She also talks about the need to reform the trading system so it works better for all parties. The Interview brings you conversations with people shaping our world, from all over the world.
