US prepares raft of new global tariffs

The White House is preparing new global tariffs following previous levies that were invalidated by US courts. The Trump administration's 10% duties on trading partners expired after 150 days without Congressional approval, and a successor regime is expected. New proposals include 50% tariffs on Canada, based on allegations of unfair trade practices, and are unlikely to be overturned, with analysts predicting a lasting protectionist policy.
