It's the United States' party. But Mexico wants a say on the guest list

Mexico's President Andres Manuel Lopez Obrador has insisted all countries in the hemisphere be allowed to attend the US-hosted Summit of the Americas.

(CNN)A growing number of countries are threatening to snub the US-hosted Summit of the Americas next month, amid controversy over its guest list.

The summit, organized this year by US President Joe Biden's administration, was intended to convene leaders from across the Americas in Los Angeles to discuss common policy issues. As host country, the United States has the right to draw up its guest list.
In April, US Assistant Secretary of State Brian Nichols told reporters that authoritarian Cuba, Nicaragua, and Venezuela were unlikely to be invited. The high-level conference would instead focus on the Western Hemisphere's democracies, Nichols said.
    While White House officials emphasize that the guest list is not yet finalized, even democratically elected leaders in the region are now warning that they won't attend the summit if not all countries are invited.
      Notably, President Andres Manuel Lopez Obrador of neighboring Mexico has said that if other countries in the Americas are excluded, he would stay home in solidarity. "If they're excluded, if not all are invited, a representative from the Mexican government would go, but I wouldn't," Lopez Obrador said during his regular news conference last Tuesday.
      Lopez Obrador's threats appear to have caused Washington to reconsider their position.
      On Monday, Lopez Obrador said Mexico is "in dialogue" with the US.
        "At least, they [United States] have acted in a respectful manner, there has not been a total, cutting rejection," he said.
        The Summit of the Americas has taken place every three years since 1994 -- an opportunity for the US to shape policy and solidify partnerships in the region.
        Cuba was excluded until 2015, when then-US President Barack Obama seemed to close a chapter of the cold war, sitting down with Cuban leader Raul Castro in Panama. The island returned to the conference in 2018 -- though the welcome was much chillier from the then-Trump administration, with then-US vice president Mike Pence criticizing its "tired Communist regime," and walking out during the Cuban Foreign Minister's rebuttal.
        Cuba, so far largely frozen out by the current administration, is seeking an opportunity to protest directly to Biden increased US sanctions. Excluding the Communist-run island entirely this year -- as well as allied Nicaragua and Venezuela -- would be a pointed message on the part of the Biden administration.
        The US has good reason to exclude some governments, says former US diplomat Eric Farnsworth, who worked on the inaugural summit of the Americas in Miami in 1994. "This particular forum is expressly reserved for democratically leaders and that's what the Biden administration is grappling with," he told CNN.
        The US regards the elections of Venezuelan President Nicolas Maduro -- who is under US indictment for drug trafficking -- and Nicaraguan president Daniel Ortega as illegitimate.
