The U.S. and Mexico agreed last week on a deal that would allow Mexican trucks to deliver to destinations in the United States and lead Mexico to drop $2.4 billion a year in retaliatory tariffs it has imposed on U.S. products.

The Mexican government, after the U.S. announced it would moving forward with talks to reopen its southern border to truck traffic,  said last week it was suspending the practice of rotating goods subject to punitive tariffs.

The Obama administration last week took the first step toward reinstituting commercial truck traffic between the United States and Mexico, although it said details would not be released for several months.

Mexico has continued its side of the cross-border trucking pilot program begun in 2007, although the United States ended its participation and has denied Mexican trucks authority to deliver to U.S. destinations, a Mexican official said.

Mexico will gradually reopen a toll highway linking Monterrey, Mexico, to Laredo, Texas, to large commercial trucks only and exempt them from paying tolls, Bloomberg reported.

U.S. efforts to resolve the ongoing dispute with Mexico over cross-border trucking have stalled, rankling officials on both sides of the border.
