Arias Sánchez, the former president of Costa Rica who was awarded the Nobel Peace Prize in 1987, has had his visa revoked without explanation this week. The New York Times reported that Sánchez has been a "vocal critic" of President Donald Trump and that the rescission of his visa "appears to be the most high profile in a string of individuals who have had their visas canceled or been denied entry as the Trump administration bars people who it says have 'hostile attitudes' toward the United States.

In his inaugural address, President Trump said his “proudest legacy will be that of a peacemaker and unifier.” But critics have accused him of siding with the aggressor when it comes to Russia and Ukraine.

Arias is not the only Costa Rican to have had his US visa revoked. Three members of the country's national assembly who opposed President Chaves's decree to exclude Chinese companies from participating in the development of 5G have also had theirs cancelled.
