TOKYO -- U.S. President Donald Trump's decision on Thursday to impose steep tariffs on steel and aluminum imports has sparked concern over excess supply in Asia and the possibility of a trade war.
In a highly unusual move, the Trump administration cited national security as a reason for imposing a 25% tariff on steel and 10% levy on aluminum. The U.S. Commerce Department argues that relying on imported metals would make the country unable to meet its military needs in a time of war.
