Tensions over disputed China zone

Available for over a year

The United States says it will continue flights over disputed territory in the East China Sea, after China scrambled fighters to follow planes entering its newly-declared air defence zone. We ask whether the tensions can be defused. Also the head of a major Qatari bank defends the Arab state against accusations that migrants working on infrastructure for the 2022 World Cup are being mistreated. And we hear from a couple who left the United States to open a restaurant in Rwanda. We're joined live throughout the programme by the business editor of ABC News in Australia, Peter Ryan.
