Davos, Switzerland (CNN Business) Treasury Secretary Steven Mnuchin said Wednesday that the United States would consider imposing tariffs on cars made in the United Kingdom if the country moves ahead with a tax on digital services.

Mnuchin said at the World Economic Forum in Davos, Switzerland that the United States regards digital services taxes such as the one imposed by France, and being planned by the United Kingdom and Italy, as being unfair to American tech companies.

President Donald Trump and his French counterpart, Emmanuel Macron, agreed this week to a truce over the issue after the White House threatened to significantly increase tariffs on French goods such as wine, cheese and handbags. France has already introduced a 3% tax on digital services.

Asked what would happen if Britain moves ahead with its tax, Mnuchin said that Washington would consider imposing tariffs on UK car exports.
