MEXICO CITY — In a blow to President Biden, the president of Mexico, Andrés Manuel López Obrador, said Monday that he would not attend the Summit of the Americas in Los Angeles after news emerged that the United States would not invite Cuba, Venezuela and Nicaragua to the meeting.
Mr. López Obrador had threatened to boycott the summit for weeks unless all countries in the Americas were invited, but during his morning news conference he made good on his promise, announcing that Foreign Minister Marcelo Ebrard would attend in his stead.
“I can inform the people of Mexico that I will not go to the summit,” Mr. López Obrador said. “I won’t go to the summit because not all countries in the Americas are invited.”
The announcement from Mr. López Obrador is a rebuke to the Biden administration, coming hours before the start of a summit that is meant to demonstrate the resurgence of U.S. leadership in the region.
Instead, the summit will go ahead without the leader of the United States’ most important trading partner, and the second-largest economy in the region.
