Mexico says it will increase tariffs on about 90 U.S. products in retaliation for last week's decision to cancel a pilot program that allowed some Mexican trucks to transport goods within the United States.
The Mexican Economy Department says the U.S. decision violates a provision of the North American Free Trade Agreement that was supposed to have opened cross-border trucking years ago.
Department officials told a news conference Monday that the measure will affect about $2.4 billion in trade: 90 agricultural and industrial products from 40 U.S. states.
It did not name the products or specify the amount by which import tariffs will increase.
Activists in the United States had argued that Mexican trucks were unsafe, something Mexico denies.
