U.S. President Donald Trump and Colombian President Gustavo Petro ended their public tit for tat that began when military planes with migrants were blocked, a disagreement that veered into tariff threats on both sides.

President Donald Trump on Sunday announced retaliatory tariffs on Colombia after its president blocked US military deportation flights from landing, the first instance of Trump using economic pressure to force other nations to fall in line with his mass deportation plans since he took office last week.

Colombia will reject deportation flights from the United States after Brazil decried the treatment of migrants arriving handcuffed and shackled, complicating President Donald Trump’s plans and providing a contrast with the cooperative acceptance of Mexico and Guatemala.
