Donald Trump administration loses trade battle over tuna as WTO lets Mexico hit US with sanctions

The US has just lost a major trade battle with Mexico and it revolved around tuna.On Tuesday, the World Trade Organisation ruled that Mexico is allowed to impose $163m (£127m) a year in sanctions against the US on trade in tuna, ending a years-long dispute.The clash, which dates back to 2008, centred on the US insisting that any Mexican tuna sold in the US must have a ‘dolphin safe’ guarantee, meaning that no dolphins were killed by fishermen catching the tuna.
