Colombia backed down in a dispute over flights of deported migrants after the new US president threatened to impose steep tariffs.

The White House on Sunday said it would hold off on the tariffs, saying Colombia had "agreed to all of President Trump's terms."

Colombia did an about-face at lightning-fast speed on accepting deportation flights in what President Donald Trump hailed as a victory for his "f--- around and find out" [FAFO] style of governing.
