Starmer spoke to reporters while hosting German Chancellor Olaf Scholz at his country estate on the eve of a mission to improve relations with the European Union.

“In the discussions that I have had with President Trump, that is what we have centered on, a strong trading relationship,” he said. “So it is very early days.”

Canada and Mexico ordered retaliatory tariffs in response to Trump’s announcement that the U.S. on Tuesday will stick a 25% levy on imports from Canada and Mexico and 10% on goods from China. Trump said he “absolutely” plans to impose tariffs on the EU.

The U.K. left the EU in 2020, following a referendum in 2016. Trump, who supported the Leave side in the Brexit vote, has not yet said whether he plans to target the U.K with tariffs.

The tit-for-tat tariffs have triggered fears of a global trade war.

“Tariff increases really right across the world can have a really damaging impact on global growth and trade, so I don’t think it’s what anybody wants to see,” British Home Secretary Yvette Cooper told the BBC.

Starmer is heading to Belgium to meet with EU chiefs Monday, where the U.K. leader is aiming for a relationship “reset”.

While ruling out rejoining the EU. trade bloc five years after Brexit, Starmer said he wants to forge a closer relationship on defense, energy and trade.

“I think that is certainly in the U.K.’s best interest, I do believe it’s in the E.U.’s best interest, and already I hope that in the last seven months there’s been a manifest difference in approach, tone and relationship,” he said.

Starmer hosted Scholz at Chequers, the prime minister’s country residence in Buckinghamshire 30 miles (50 kilometers) northwest of London, where the two leaders discussed Ukraine and the Middle East, according to a Starmer spokesperson.

The prime minister spoke of their common approach to “key issues and challenges,” including their shared commitment to Kyiv as the war with Russia enters its fourth year this month.

The two agreed that Russia’s invasion had emphasized the need to beef up and coordinate defense production across Ukraine, according to a readout of the meeting from a Starmer spokesperson. The U.K. and Germany signed a defense pact in October, described by officials as the first of its kind between two NATO member countries, to boost European security amid rising Russian aggression.

The British government’s strategic defense review later this year will include lessons learned in Ukraine and the need to outmaneuver Russian President Vladimir Putin’s hostile acts across the continent, Starmer said.

Starmer thanked Scholz for visiting in the middle of a difficult re-election campaign. Scholz’s center-left Social Democrats are lagging in the polls behind the center-right Christian Democratic Union and the far-right Alternative for Germany, or AfD, with three weeks to go before the Feb. 23 vote.

“When I started as prime minister seven months ago now, I was determined to strengthen the relationship between our two countries — already very good, but I thought it could be stronger on a number of fronts,” said Starmer, leader of the center-left Labour Party. “And thanks to your leadership, I think we’ve made real progress.”

Scholz said the visit that included a walk around the grounds of the estate and a lunch was a “good sign of the very good relations between our two countries, and indeed between the two of us.”
