Nicaragua on Monday recalled its ambassador to Argentina ahead of radical right-wing libertarian Javier Milei’s presidential inauguration following his criticism of the Nicaraguan government.

Milei takes office on December 10. In the lead-up to his November election win, Milei said Argentina would not do business with “dictators” or “communists,” and that he would withdraw its ambassador to Nicaragua, among others.

Nicaraguan President Daniel Ortega and Vice President Rosario Murillo initially congratulated Milei on the win, but Nicaragua’s foreign ministry said the withdrawal of its ambassador comes “in the face of repeated declarations and comments” from the incoming Argentine government.

Ortega, a former Marxist guerrilla, has been increasingly isolated internationally since he launched a violent crackdown on dissent after protests against him erupted in 2018. The president said he was forced to act, arguing that adversaries were attempting a coup against him.

Since his election, Milei has softened his tone with some of the countries he had criticized on the campaign trail, including China and Brazil.

A representative for Milei did not immediately reply to a request for comment.
