The two leaders have little in common ideologically — Mr. López Obrador is an avowed leftist — but Mr. Trump has used America’s tremendous economic leverage, including threats of tariffs and even a total border closing, to pressure the Mexican leader.
Mr. López Obrador stylistically shares some of Mr. Trump’s bombast but eschews displays of wealth, including the use of a private presidential plane. He flew commercial to Washington from Mexico City on Tuesday, his first foreign trip since his landslide 2018 election, connecting through Atlanta.
After afternoon meetings, the leaders will sign a joint declaration before dining with Mexican and American business executives. A senior administration official said the event amounted to a state dinner “lite,” within the limits of coronavirus precautions.
On Wednesday morning, Mr. Trump’s re-election campaign issued a statement hailing the revised NAFTA deal, known as the U.S.M.C.A., calling it a “stark contrast” to “Joe Biden’s failed globalism.”
A Canadian spokeswoman said that Prime Minister Justin Trudeau had chosen not to travel to the United States this week to celebrate the U.S.M.C.A. because of a scheduling conflict with a session of Parliament on Wednesday. But relations between the Trump administration and Canadian officials have turned chilly since last month, when American officials said their Canadian counterparts must voluntarily restrain their own metal exports or face tariffs again.
