Mexico's deputy minister of foreign trade, Juan Carlos Baker, opens the door to an update of the trade agreement, but rules out tariffs schemes and quotas. "We have to keep the free trade spirit in North America to remain competitive," he tells Jacopo Dettoni, fDi Magazine's deputy editor. Donald Trump's trade advisers also suggested to toughen up Nafta's rule of origin, which grants duty-free movement between Mexico, the US and Canada to productions whose local content exceeds a certain threshold, but that has to be seen "on a case by case basis", Mr Baker notes.
