Asked in an interview on Fox News "you can't do Nafta before the midterms", Trump responded, "I want to wait until after the election". "We will not escalate and we will not back down", she said, while noting that this trade action was the strongest Ottawa has taken since World War II.
The response from Canada is created to be proportional, with the new taxes being based on the amount of steel and aluminum shipped a year ago from Canada to the United States.
After the election, Lopez Obrador said he'll propose that his own team of experts be included in the trade talks.
Lopez Obrador told the Televisa network Monday that he will respect the current team of negotiators, and let them continue representing Mexico until he takes office December 1, noting that he wants to have information on what's being discussed and "to help as much as we can".
Trump had enraged Canada and other USA allies by declaring imported steel and aluminum a threat to America's national security and therefore a legitimate target for US tariffs.
Canada's response includes imposing $16.6 billion worth of tariffs on a long list of consumer products that come from a wide range of sectors - from beer kegs, to ballpoint pens, to ketchup. "The president is working to fix the broken system and he'll continue pushing for that".

Trump went farther than that in attacking Heitkamp, calling her a "liberal Democrat" who blindly follows "Chuck and Nancy". Trump had once courted Heitkamp, even inviting her to NY to discuss a Cabinet post soon after his 2016 election victory.
Canada's retaliatory tariffs on US goods take effect Sunday following the Trump administration's new tariffs on Canadian steel and aluminum.

"I think he is going to be a better negotiator because of this", Gomez said.
"The two leaders agreed to stay in close touch on a way forward", it added.
Now, Trudeau is reaching out to the new president in the hopes of maintaining a united approach with Mexico when talks do resume with the United States.
On Monday, Prime Minister Justin Trudeau spoke with Lopez Obrador by phone.
In an interview that aired Sunday morning, Trump said he will delay signing a revised version of the North American Free Trade Agreement until after the USA mid-term elections in November in hopes of reaching a better deal.
