NAFTA nations plan talks progress under barrage of Trump threats

THROWING WORDS ABOUT

Trump has accused Mexico and Canada of being "very difficult", and officials from both countries say his words come as little surprise given his confrontational negotiating style.

Still, Mexico's government has touted a back-up plan, seeing a "high risk" that NAFTA could unravel.

Canada's Prime Minister Justin Trudeau on Tuesday shrugged off the threats and Canadian officials close to the process said they remained fully focused on the talks.

"There are always going to be words thrown about here and there but ... we will continue to work seriously and respectfully to improve NAFTA to benefit not just Canadians but our American and Mexican friends as well," Trudeau said.

A spokeswoman for U.S. Trade Representative (USTR) Robert Lighthizer declined to comment directly on how Trump's comments would affect the talks. However, trade experts say they are unlikely to foster a spirit of cooperation.

"I think his tweets and statements are just complicating what's already a difficult negotiation," said Wendy Cutler, a former deputy USTR and lead U.S. negotiator for the TPP.

"I think it will embolden the naysayers in Canada and Mexico who don't want to move in certain areas by telling the negotiators, 'don't move on these issues because the president has already said he probably won't sign off on this deal'".
