Biden met with Johnson on Thursday in the English seaside town of Carbis Bay during his first trip overseas as president.
Though Johnson said the talks were "great," Biden brought grave concerns about a row between Britain and the European Union which he said could threaten peace in the British region of Northern Ireland, which following Britain's departure from the EU is on the United Kingdom's frontier with the bloc as it borders EU member state Ireland.
Asked whether Biden pressured him over the issue during discussions, Johnson said "no, the president didn't say anything of the kind". Johnson said "everybody has a massive interest in making sure that we keep the the essential symmetry of the Good Friday Agreement".
Johnson has already called on G7 leaders to commit to vaccinate the entire world by the end of 2022 and the group is expected to pledge 1 billion doses during its three-day summit in the English seaside resort of Carbis Bay.
The prime minister also said he discussed the case of Harry Dunn with the president who was "extremely sympathetic".
Dunn was a British teenager who was killed in a car crash involving a U.S. diplomat's wife, Anne Sacoolas, in 2019. The U.S. refused to extradite her last year.
Johnson and Biden will join other leaders of the Group of Seven (G7) wealthy nations begin a three day meeting in Cornwall, England, on Friday I(June 11), discussing issues ranging from COVID-19 vaccines and economic recovery to climate change and geopolitics.
