Mr. Trump’s decision to impose tariffs on metals is not new. In his first term, the president levied tariffs on foreign steel and aluminum globally, angering allies like Mexico, Canada and the European Union. He ultimately rolled back some of those barriers on Canada and Mexico when they signed a revised trade agreement with the United States.

If they are charging us 130% and we’re charging them nothing, it’s not going to stay that way,” he told reporters.

The 25 percent tariffs on imported steel and aluminum are the latest salvo in his ongoing effort to overhaul the U.S. trading relationship with the rest of the world.
