Global markets continue to struggle after a difficult week

The White House has insisted that President Trump’s tariffs will make the United States richer, despite the falling value of the US dollar. We hear from Tomas Philipson, a former acting chairman of President Trump's Council of Economic Advisers. Also, a global deal to tackle shipping emissions has been agreed after nearly ten years of negotiations. The UN's maritime agency (the IMO) brokered the accord, which requires ship owners to use less carbon-intensive fuels or face a penalty. Roger Hearing speaks to IMO's secretary general, Arsenio Dominguez, about how it would work. And on Saturday, the UK is going to see an emergency recall of parliament when members had already departed for their Easter break, and they are recalled to discuss a law to take control of the Chinese-owned British Steel and save it from imminent closure.

Throughout the programme, we’ll be joined by two guests on opposite sides of the world – Peter Ryan, ABC's senior business correspondent, who's in Sydney, and Takara Small, national technology columnist for the CBC, who's in Toronto.
