A short-lived tariff feud with the Latin American nation underscored the president's propensity to use economic sanctions as political leverage.

Coffee prices hit a new high Monday, the day after President Donald Trump threatened – and then reversed course on – a 25% tariff on Colombia during a spat about deportation flights from the US. And the price is still rising.

Trump has repeatedly insisted that tariffs are coming on Canada and Mexico, despite both countries seeking to address his stated concerns about illegal border crossings and the smuggling of fentanyl. But the Republican president is also motivated by the idea that tariffs would force other countries to “respect” the United States.
