EU ministers yesterday will refine a last-ditch bid to persuade US President Donald Trump to back off stiff tariffs on metals imports from Europe and win the bloc a similar break as handed China, reports AFP from Brussels.

Europe was hit by the shock tariffs in March, part of the protectionist president’s threat of an “America First” trade war with Washington’s closest partners, including Canada, Mexico and Japan.

The European Union has said it refuses all trade talks with the United States unless Washington grants a permanent exemption from the painful steel and aluminium tariffs that are set to kick in on June 1.

However, trade ministers from the bloc’s 28 member states will discuss a plan laid out by EU leaders for a limited EU-US trade deal as well as opening up the European market to US natural gas—if the exemption is granted.

“The EU is ready to talk about trade liberalisation with our American friends but only if the US decides an unlimited exemption from steel and aluminium tariffs,” EU President Donald Tusk told reporters after the conclusion of a summit in Sofia on Thursday.

The ministers will take encouragement from the US-China development on Sunday with Washington and Beijing backing off from tit-for-tat tariffs after reaching an as-yet specified accord on slashing the massive American trade deficit with China. Europe’s incentives come with a threat to retaliate against the US with European tariffs on American imports, including iconic items such as Harley-Davidson motorbikes and bourbon whiskey.

These counter-measures will officially become enforceable on June 20, but Europeans have committed to not use them as long as talks with the US are ongoing.

Trump announced the duties of 25 per cent on imported steel and 10 percent on aluminium in March, but has twice accepted to suspend their effect as talks with key allies continued.
