(Adds Guajardo, Trump comments)
By Daniel Flynn
SAO PAULO, March 15 (Reuters) - Mexico's economy minister on Thursday urged officials to push for a speedy renegotiation of the North American Free Trade Agreement (NAFTA), saying his country and Canada must be ready to go it alone if the United States pulls out.
Economy Minister Ildefonso Guajardo said if no deal to rework NAFTA could be struck by April 30, then the new political complexion of the region would cast doubt on how incoming lawmakers would view it in Mexico and the United States.
"The whole nature of the agreement would change," Guajardo said at the World Economic Forum on Latin America in Sao Paulo. "You either get it done by the end of April or then it doesn't matter: you can go until the end of the year."
Guajardo had previously identified a window for negotiation extending through July, though his comments come a few days after U.S. Trade Representative Robert Lighthizer floated the idea of reaching a deal "in principle" in the next few weeks. regular session of Congress in Mexico ends on April 30, and the country will elect a new president in July who takes office at the start of December. The United States will hold mid-term congressional elections in November.
Mexico's government is eager to broker a deal before a change of presidency, and Guajardo has also said his team would be ready to keep talking until the end of November.
Speaking with Reuters on the sidelines of the event, Guajardo said he thought it was probable that the negotiations would drag on beyond April.
Nonetheless, he said it could be possible to complete the technical work in a month.
"If there's political will and flexibility to reach an agreement, I think it's technically not impossible," he said in an interview.
Guajardo has stressed that Mexico wants to keep NAFTA tri-partite, but reiterated that both Mexico and Canada needed to be ready for the possibility of a U.S. departure.
"You have to be ready to live with a NAFTA without the U.S." Guajardo said. "NAFTA at risk of ending? No. NAFTA will continue between Canada and Mexico because at the end of the day, what is important is you send a message that you believe in free trade. The U.S. is the one that will decide to be in or out."
A vast majority of Mexicans remained in favor of free trade, and U.S. President Donald Trump was coming under increasing pressure from political supporters in farming states to renew the trade deal, the Mexican minister said.
If NAFTA was not reworked soon, terms of negotiation could be shifted by political developments, such Democrats winning control of the U.S. Senate, Guajardo said. He noted that Democrats claimed victory this week in a special congressional election in Pennsylvania in a district Trump had won in 2016. The vote tally officially remains too close to call. at a fundraiser in the state of Missouri on Wednesday, Trump reiterated that he thought it best to kill NAFTA and strike a new deal.
"Let's start all over again ... because the best deal is to terminate it and then make a new deal," Trump said, according to a transcript published by the Washington Post. "But I don't know that we can make a deal because Mexico is so spoiled with this horrible deal that they've lived with."
Nonetheless, Trump's comments appear to contradict statements made by his newly installed director of the White House National Economic Council, Larry Kudlow.
On Wednesday, Kudlow said he thought NAFTA needs to be reupholstered in many ways, but ditching it would have bad consequences.
