How the US' trading partners should respond to Trump's coercive strategy of ‘tariffication'

This week Donald Trump’s second administration threatened to impose 25 percent tariffs on imports from Mexico and Canada and ten percent tariffs on China (at time of writing, there is a 30-day pause for Canada and Mexico). Mona Paulsen writes that Trump’s weaponisation of tariffs is a significant departure from international rules on trade. To reduce uncertainty for firms and supply chains, she argues that these governments need a coordinated response to the US tariff threats and actions.
