MEXICO CITY — A new set of U.S. goods will get slapped with retaliatory tariffs if Washington doesn’t move quicker to resolve the cross-border trucking dispute between the two countries.

The "clock is ticking" for the U.S. to allow Mexican trucks to cross the U.S. border beyond the 20-mile commercial restriction zone, Mexico’s economy minister told Reuters.

A Mexican trade official told the news agency that the government is prepared to periodically shuffle the list and quantity of U.S. goods it hits with tariffs.

Mexico first implemented the tariffs after the Obama administration cancelled Bush’s truck demonstration project which permitted select Mexican trucks access to the U.S. market.

In August, Mexico increased tariffs from 89 products to 99 — which included pork, cheeses, and some fruits – as a message to the White House that it should lift the ban soon.

And last month Mexico said it won’t be satisfied with another pilot project. The Mexicans want permanent access, which they insist is their right under NAFTA.

The U.S. has insisted for months that it is "very close" to finalizing a new proposal. It’s likely, though, that the U.S. mid-term elections delayed a official announcement.
