Hundreds of Mexican soldiers were mobilized on Tuesday to the border with the United States as part of an agreement that halted U.S. tariffs on Mexican imports under the condition the Latin American country cracks down on fentanyl trafficking.

Trump on Saturday had directed that 25% tariffs on most imports from the two American partners — and 10% on Canadian energy products — go into effect at midnight Tuesday.

Tariffs will be paused for 30 days. But a 10 percent levy on Chinese goods is still scheduled to go into effect.

Mexico agreed to rush 10,000 national guard troops to the border to strengthen efforts to block the flow of drugs, especially fentanyl, coming into the United States.
