When asked by the BBC if there was a timeline for announcing tariffs on the European bloc, Trump said: “I wouldn’t say there’s a timeline, but it’s going to be pretty soon.”

For its part, the 27-member bloc has condemned Trump’s decision to move ahead with tariffs against Canada, Mexico and China, and warned that it will “respond firmly” if it also becomes a target.

Mexico and Canada have vowed to take retaliatory measures, while China said it could take “corresponding counter measures”.

On trade with the UK, the US President said the country has been “out of line” but added that the issues could be resolved.

“The UK is out of line. But I’m sure that one, I think that one, can be worked out,” Trump said.

The US President also discussed his relationship with the British Prime Minister who he said has been “very nice”.

“We’ve had a couple of meetings. We’ve had numerous phone calls. We’re getting along very well,” he added.

Last week, British business secretary, Jonathan Reynolds, told the BBC that the UK should be exempted from any tariffs, noting that the US does not have a goods trade deficit with the UK – which happens when a country imports more than it exports.

Tariffs are a central part of Trump’s economic policy. He sees them as a way of growing the US economy, protecting jobs and raising tax revenue.

But many economists warn that these tariffs could lead to higher prices for American consumers and could ultimately encourage other countries to reduce their reliance on the US.
