WHISTLER, British Columbia (Reuters) - The United States' closest allies attacked the Trump administration on Friday for imposing tariffs on steel and aluminium imports and mounted challenges with the world's top trade body, fouling the mood at a G7 finance leaders meeting.

U.S. Treasury Secretary Steven Mnuchin was the prime target of the criticism at the meeting of Group of Seven finance ministers and central bank governors in Canada, with the six other G7 member countries subject to the U.S. metals tariffs, which were imposed on national security grounds.
