Canadian Prime Minister Justin Trudeau will not attend talks in Washington later this week to mark the beginning of a new North American trade deal, Mexican President Andres Manuel Lopez Obrador said.
He added that the two leaders will have a phone conversation later in the day.
Mr Obrador is scheduled to meet US President Donald Trump at the White House on 8 July.
Last week, Canadian Prime Minister Trudeau said that he may not take part in a trilateral summit in Washington, adding that he would consider the latest US threat to impose more tariffs on Canadian goods as well as risks linked to the coronavirus pandemic before making a final decision on his participation in the talks.
The United States-Mexico-Canada free trade agreement (USMCA) came into force on 1 July, replacing the 1993 North American Free Trade Agreement (NAFTA). The new pact retains NAFTA’s list of products eligible for zero tariffs but also makes it obligatory for Canada to provide expanded access to US dairy exports.
