UNITED STATES.- President Donald Trump intends to delay signing a revised version of the North American Free Trade Agreement until after the fall midterm elections, a move aimed at reaching a better deal with Canada and Mexico.

Trump said in an interview that aired Sunday that he could quickly sign an agreement with the United States’ neighbors,“but I’m not happy with it. I want to make it more fair.”Asked about the timing of an agreement, Trump said: “I want to wait until after the election.

The president’s decision to push back the Nafta talks comes as the U.S. and Canada have been engaged in a tit-for-tat trade dispute over Trump’s tariffs on Canadian steel and aluminum. Canada announced billions of dollars in retaliatory tariffs against the U.S. on Friday, and the president signaled the trade rattling could continue.

In the interview on Fox News Channel’s “Sunday Morning Futures with Maria Bartiromo,”Trump again threatened to impose tariffs on imported cars, trucks and auto parts, saying,“The cars are the big ones.” The move has been viewed as a possible negotiating ploy to restart Nafta talks, which could resume following Sunday’s elections in Mexico.

If the U.S. moved forward with tariffs on auto imports, it would be a blow to Canada’s economy because of the critical nature that the auto industry plays in the country. The U.S. Commerce Department is expected to hold hearings on auto tariffs in late July and to complete its investigation into auto imports later this summer.

Trump has sought to renegotiate Nafta to encourage manufacturers to invest more in America and shift production from lowwage Mexico to the United States. The talks have stalled over several issues, including Trump’s insistence on a clause that would end Nafta every five years unless all three countries agree to sustain it.
