Donald Trump announces new tariffs on steel and aluminium
The tariffs are due to come into effect in 15 days butCanada and Mexico will be exempt.
US President Donald Trump has announced steep tariffs on imports of steel and aluminium to address what he says is an "assault on our country."
Mr Trump said a 25% tax will apply to steel imports, and 10% will be added to aluminium brought into the US.
The president said the excess of imported steel and aluminium is a "travesty" and hurts American workers and industry.
In making the long-awaited announcement, Mr Trump says the US industry has been "ravaged by aggressive foreign trade practices".
"It's really an assault on our country," Mr Trump said.
Sources outside the White House said the tariffs will take effect in 15 days, with Canada and Mexico indefinitely excluded from the duties.
Those briefed on the plans say all countries affected by the tariffs are being invited to negotiate for exemptions, if they can address the threat their exports pose to the US.
