DONALD Trump has announced he will double the tariffs on steel and aluminium imports to 50 per cent in his latest trade war escalation.

It comes after the president’s blistering global tariffs were reinstated by a federal appeals court – just a day after they were ruled illegal and sensationally blocked.

 While addressing workers at a US Steel plant in Pennsylvania, Trump said: “We’re going to bring it from 25 per cent to 50 per cent, the tariffs on steel into the United States of America.

“Nobody’s going to get around that.”

Shortly after, Trump wrote in a Truth Social post that the elevated rate would also apply to aluminum, with the new tariffs “effective Wednesday, June 4th.”

Trump has imposed sweeping tariffs on allies and adversaries alike in moves that have rocked the world trade order.
