The move followed a dispute between President Trump and President Gustavo Petro over deportation flights that nearly turned into a costly trade war between both countries.

The U.S. Embassy in Colombia canceled Visa appointments on Monday with people seeking entry into the United States, the latest chapter in a nasty battle between the two countries sparked by Colombia’s initial refusal to accept military flights filled with deportees sent by President Trump.

Colombia avoided tariffs that would have a devastating effect on its economy, but visa restrictions issued on Sunday by the U.S. State Department are still in place.
