Deportation flights between the U.S. and Colombia have resumed following a dispute between the two countries that nearly led to a trade war.

Colombian President Gustavo Petro announced that Colombia was suspending permission for previously authorized U.S. deportation flights to land in Colombia. Ostensibly driving Petro’s action were concerns that Colombian nationals were not being treated with respect during the deportation process because they were being transported by military aircraft.

The nations spent much of the day in a tense standoff, with the U.S. president threatening tariffs and visa restrictions after Colombia turned away two deportation flights.

A simmering diplomatic stand-off over deportation flights spilled onto social media Sunday, threatening the once close relationship between the US and Colombia and further exposing the anxiety many feel in Latin America towards a second Trump presidency.
