US President Donald Trump said he will not impose quotas on importing uranium. The decision is unusual for Mr Trump, who has pointed to national security concerns in calling for restrictions on foreign metal and autos in trade negotiations. Uranium is a vital component for the U.S. nuclear arsenal, submarines and power plants.

Commerce Secretary Wilbur Ross has said that just five percent of the uranium the US needs for military and electricity generation comes from domestic production. Russia, China and other countries supply the rest.

Mr Trump said,  he was going to order a working group to use 90 days to make recommendations to increase domestic uranium production.
