MEXICO CITY (Reuters) - Mexican Economy Minister Ildefonso Guajardo said on Wednesday that the goal of Canada, the United States and Mexico is to be in a position to sign a new North American Free Trade Agreement (NAFTA) by the end of November.

The three nations have been negotiating to revamp the 24-year-old trade pact since August, but talks have stalled over U.S. demands on autos and other issues, and while negotiators waited out Mexico’s recent presidential election.
