Mexico and the U.S. have fought for years over tuna. The U.S. insists that any Mexican tuna sold in the U.S. must be "dolphin safe," meaning dolphins weren't killed by tuna fisherman, which was once common. Mexico says its fisherman play by the rules. The U.S. government disagrees.
On Tuesday, the World Trade Organization ruled in Mexico's favor, allowing it to impose trade sanctions worth $163 million a year against the U.S. The WTO says that's how much money Mexico has lost from the U.S. unfairly penalizing Mexican tuna.

I wonder where that $163 million is going to come from? Taxpayers?
