PANAMA CITY >> First lady Jill Biden arrived in Panama today, her second stop on a three-country Latin America visit before the United States hosts the Summit of the Americas next month in Los Angeles.

Biden landed in Panama City around midday and went directly to the presidential palace for a meeting with Yasmín Colón, Panama’s first lady.

The two first ladies were scheduled to visit a nearby school to learn about Colón’s “See and Hear to Learn” program, which provides eye and hearing exams — and eyeglasses and hearing aids, as needed — to students.

Biden arrived from Ecuador, where she emphasized the close relationship between nations of the Americas and how the economic or political situation in one can affect the others.

The Biden administration has been trying to build momentum in the region ahead of next month’s Summit of the Americas, but has faced pushback over its unwillingness to invite Cuba, Venezuela and Nicaragua to participate.

Mexico President Andrés Manuel López Obrador said last week he would not attend if countries were excluded.

Biden has said he wants to sign a regional declaration on migration and protection at the summit. The U.S. has been talking to governments throughout the region about controlling migration flows and encouraging some countries to host more asylum seekers to lessen the pressure at the U.S. border.

Panama is a critical transit country for migrants traveling from South America toward the U.S. They pass through the dense jungle of the Darien Gap that divides Panama and Colombia.
