​U.S. President Donald Trump signed an agreement on Monday formally lowering some tariffs on imports from Britain as the countries continue working toward a formal trade deal.

The deal, announced by Trump and British Prime Minister Keir Starmer on the sidelines of the G7 Summit in Canada, reaffirmed quotas and tariff rates on British automobiles and eliminated tariffs on the U.K. aerospace sector, but the issue of steel and aluminum remains unresolved.
