In a joint statement, the U.S., Canada, and Mexico claimed "important progress" was made toward updating the North American Free Trade Agreement but didn't state what exactly was achieved. The statement followed the conclusion of the second round of talks among the three countries to renegotiate the 1993 agreement.

"Over the past five days, more than two dozen working groups comprised of trade experts and technical officials worked diligently to advance the discussions and exchanged information and proposals. ... Important progress was achieved in many disciplines and the Parties expect more in the coming weeks," the countries said following the conclusion of negotations in Mexico City. The talks reportedly focused on rules-of-origin, market electronic commerce, the environment, and anti-corruption measures, according to various reports.

U.S. Trade Representative Robert Lighthizer said in a statement that the parties "found mutual agreement on many important issues," but didn't elaborate on details.

He added that the administration still viewed NAFTA as a bad deal and would continue to push for broad changes: "[A]s I alluded to in my opening round, we also must address the needs of those harmed by the current NAFTA, especially our manufacturing workers. We must have a trade agreement that benefits all Americans, and not just some at the expense of others."

President Trump has expressed frustration over the talks, last week reiterating his threat in a tweet to pull the U.S. out of the deal: "We are in the NAFTA (worst trade deal ever made) renegotiation process with Mexico & Canada.Both being very difficult,may have to terminate?"
