Donald Trump has introduced eye-watering tariffs on countries around the world. Will they ‘make America wealthy again’? Richard Partington reports

Donald Trump is on a mission to ‘make America wealthy again’. Speaking outside the White House, he said for too long the country had been ‘looted, pillaged, raped and plundered by nations near and far, both friend and foe alike’. Now that would come to an end, he said, as he slapped eye-watering tariffs on countries around the world.

The Guardian’s senior economics correspondent, Richard Partington, explains why Trump has taken such action and how it could affect the global economy. ‘It could come at huge costs to consumers,’ he says, as markets around the world react with confusion. With prices in the US also likely to rise, will voters soon rue what the president has called ‘liberation day’?
