U.S. President-elect Donald Trump said on Friday the European Union should step up U.S. oil and gas imports or face tariffs on the bloc's exports that include goods such as cars and machinery.

US president-elect Donald Trump has warned the EU that it must commit to buying “large scale” amounts of US oil and gas or face tariffs, in his first trade salvo against Brussels since his election victory.

Donald Trump has threatened to impose import tariffs on the European Union unless it carries out large scale purchases of American oil and natural gas.
