President Joe Biden has called US government actions "clumsy" during his first meeting with French President Emmanuel Macron since a diplomatic crisis erupted last month over a US security pact with the UK and Australia.
Biden used the meeting at the G20 summit in Rome, Italy, to try to turn the page on a relationship that came under strain over the US-Australia security alliance, known as AUKUS, which also includes the United Kingdom.
The pact effectively cancelled a 2016 Australian-French submarine deal.
The US decision to secretly negotiate a new agreement drew outrage from officials in Paris.
"I think what happened was - to use an English phrase - what we did was clumsy. It was not done with a lot of grace," Biden said.
"I was under the impression certain things had happened that hadn't happened. And - but I want to make it clear: France is an extremely, extremely valued partner - extremely - and a power in and of itself."
Biden also said the United States does not have an older and more loyal ally than France and that there is no place in the world where the United States cannot co-operate with France.
"I was under the impression that France had been informed long before that the deal was not going through. I, honest to God, did not know you had not been," Biden told Macron.
Macron said his meeting with Biden was "important" and that it was essential to "look to the future" as his country and the United States work to mend fences.
"What really matters now is what we will do together in the coming weeks, the coming months, the coming years," Macron said.
Macron told reporters after the meeting: "We are building the trust again. Trust is like love. Declaration is good, but proof is better."
The French leader said he believed Biden was sincere when he said he thought France had been informed about the submarine deal by the UK and Australia.
Since the rift erupted, the US has taken several steps to fix the relationship.
Biden and Macron spoke to each other last week.
Secretary of State Antony Blinken also visited Paris, where he acknowledged the United States could have "communicated better".
Vice President Kamala Harris also announced that she would travel to Paris in November and meet with Macron.
Biden and Macron met at the Villa Bonaparte, the French embassy to the Vatican, which a French diplomat said was a significant mark of goodwill from Biden.
"It's an important gesture," the French diplomat said, adding that the United States recognised that it underestimated the impact of its actions.
France now wants to see if Biden follows his words with actions.
"Trust is being rebuilt. This is one step. Tokens of goodwill were given, we'll see whether they follow through over the long term," the diplomat said.
