EU Trade Commissioner Maroš Šefčovič said he had a "very positive" meeting with US Trade Representative Jamieson Greer on the sidelines of a World Trade Organization ministerial meeting in Cameroon, Reuters reported.
"We agreed with the United States to continue work on critical minerals," he said, adding that tariffs were also discussed.
On Thursday, MEPs pushed through legislation to implement the bloc's side of a trade deal struck with the United States in Turnberry, Scotland, last July, after months of uncertainty over President Donald Trump's tariff threats and a new import tax.
Safeguards were added, reflecting concerns that Washington might not stick to the deal.
The United States has reached an agreement with the EU to impose 15% import duties on most EU goods - half the threatened rate - and avert a wider trade war between the two allies, which account for almost 1/3 of world trade.
Šefčovič said the vote and the positive meeting with Greer were important.
"This shows from both sides, despite the turbulence on the world stage, that we are sticking to the agreement".
The US is the EU's largest trading partner, with EU exports to the US reaching a record €555 billion ($641 billion) in 2025.
Šefčovič indicated that the EU is also looking for other trading partners.
"Our agenda for the future will be to work as much as possible with all partners who want to have a free trade agreement with us... and of course, to reduce tariffs with the partners we already trade with," he explained.
