The White House claimed victory in a showdown with Colombia over accepting flights of deported migrants from the U.S. on Sunday, hours after President Donald Trump threatened steep tariffs on imports and other sanctions on the longtime U.

Both leaders defended their actions in a series of social media posts, further straining relations between the two nations.

Donald Trump claimed an early victory for a coercive foreign policy based on tariffs and hard power on Sunday after announcing Colombia had backed down in a dispute over migrant repatriation flights.
