On Wednesday's Backchat, we looked at how the latest trade uncertainties between China and the United States have been affecting the global economy.

Beijing said it's ready to "fight to the end" in a potential trade war with Washington after US president Donald Trump threatened an additional 100-percent tariff on Chinese goods. A scholar, a shipping industry executive, and a representative from the business sector talked about how all this would impact the SAR.

To end the show, an expert on coral bleaching gave us his take on a recent scientific report, which said the world's tropical reefs have "almost certainly crossed a point of no return".
