U.S. and Mexican trade negotiators are close to squaring away bilateral differences on the North American Free Trade Agreement (NAFTA) and will resume talks today, Mexican Economy Minister Ildefonso Guajardo said Sunday.

Earlier, Guajardo told reporters the two sides were likely “hours” away from reaching a common position, but in the evening he said more work still needed to be done, and that talks would start again today at 9 a.m. local time in Washington.

“We’ve continued making progress,” Guajardo said.

The Mexico-U.S. discussions have focused on crafting new rules for the automotive industry, which U.S. President Donald Trump has put at the heart of his drive to rework the 24-year-old pact he says has been a “disaster” for American workers.

Canada has sat out the most recent phase of the year-long discussions, and once it rejoined the talks, the three sides would need to work for at least another week, Guajardo said.

Leaving the offices of U.S. Trade Representative (USTR) Robert Lighthizer late Sunday, Mexican Foreign Minister Luis Videgaray said Canada would return once bilateral issues were resolved. “But we haven’t finished this stage yet,” he said.

The two sides have been gradually nearing agreement on autos, and one source close to the negotiations said at the weekend there was now “little” separating the two.

Industry sources say they are close to agreeing on raising the regional automotive content threshold for tariff-free access under NAFTA to around 75 percent from 62.5 percent.

Still, the Trump administration has been seeking to impose a cap on Mexican car and SUV exports to the United States that could be sent duty-free or at a 2.5 percent tariff, complicating the auto talks, three people with knowledge of the matter said.

Two automakers say the United States want Mexican exports of cars and SUVs to be capped at about 2 million units, up from some 1.77 million exported in 2017, excluding pickup trucks.

Including pickups, Mexico exported more than 2.3 million vehicles to the United States last year.

Mexico’s economy ministry declined to comment. A USTR representative did not respond to a request for comment.

Trump said Saturday that Washington could reach agreement with Mexico “soon” as the chief trade negotiator of Mexico’s incoming president signaled possible solutions to energy rules and a contentious U.S. “sunset clause” demand.

Since Mexico’s July 1 presidential election, the bilateral talks have been complicated by divisions between the incoming and outgoing Mexican administrations over energy policy.

The team of leftist Mexican President-elect Andres Manuel Lopez Obrador has resisted enshrining the 2013-14 opening of the oil and gas sector enacted by outgoing President Enrique Pena Nieto in the new NAFTA, people close to the talks say.

Long skeptical of foreign companies entering the Mexican oil industry, Lopez Obrador opposed Pena Nieto’s energy reform.

Jesus Seade, the incoming Mexican government’s chief NAFTA negotiator, said the issue had been “ironed out” at the NAFTA talks, without going into detail. (SD-Agencies)
