President Trump has signed controversial orders imposing heavy tariffs on steel and aluminium – but some countries will be spared.
Mr Trump has said the US is suffering from “unfair trade” and that the move would boost US industry.
But countries have expressed outrage at his plans, and experts have warned of new trade wars.
The tariffs will go into effect in 15 days and include exemptions for Canada and Mexico.
Tariffs of 25% are to be placed on steel and 10% on aluminium imported into the US.
