Trade used to be about efficiency and growth. But those goals are being overtaken by others, from security to environmentalism. Our Britain economics editor Soumaya Keynes and host Rachana Shanbhogue investigate how the blurring of economic and political concerns is driving—and destabilising—trade relationships, with global consequences.

We hear from Ngozi Okonjo-Iweala, director-general of the World Trade Organisation, about the WTO’s complicated history and contested future. US Trade Representative Katherine Tai explains where she thinks the current rules-based system falls short, particularly when it comes to China. And Pamela Coke-Hamilton, head of the International Trade Centre, identifies the winners and losers of this new era.
