Speaking to reporters with European Commission President Ursula von der Leyen ahead of a gathering of G7 leaders in the Canadian Rockies, Costa said the two days of meetings provide an opportunity to talk about “some problems” between the allies and friends.

“The main issue between Europe and the US is precisely about European defence, and we should focus on (this),” Costa said, referring to Washington’s rebalancing of foreign policy towards countering China.

“Because this is the main issue, we should avoid introducing other issues that undermine our economic capacity to assume greater responsibility on our own defence,” he said.

US President Donald Trump backed away from his threat to impose 50% tariffs on imports from the EU next month, restoring a July 9 deadline to allow for talks between Washington and the 27-nation bloc to produce a deal.

Trump’s haphazard imposition of tariffs across the world has created uncertainty among key US allies, and raised pressure on the global economy.

Speaking alongside Costa, von der Leyen said the trade talks with Washington were now focusing on the details, but there was no guarantee of a deal.

“That’s why this is not the right moment to create uncertainty on economics.

“It is not the right moment to create problems on trade, because we need to strengthen our economic basis,” Costa said.

“We are talking about the most relevant trade relations in the world, then we need to protect this and focus on what is the most important which is to have a good agreement between the EU and the US about the burden sharing on defence,” he said.

Underscoring Costa’s comments, von der Leyen said the G7 had to avoid protectionism.

“This is an important message. A message that the G7 can send to the markets and to the world,” she said.
