Colombia has walked back from the brink of a damaging trade war with the United States, reaching an agreement on accepting deported migrants being returned on military planes, after a flurry of threats from President Donald Trump that included steep tariffs.

President Donald Trump and Colombian President Gustavo Petro defended their views on social media and imposed tariffs on each other’s goods.

President Trump on Sunday announced “emergency” tariffs on imports from Colombia, an early signal of how he might enact trade policy in the early days of his second term.
