US President Joe Biden will visit the UK in June for his first overseas trip since his election victory last year.
The president will travel to Cornwall for the G7 summit, which takes place between 11 and 13 June.
From there, he will travel to Brussels, in Belgium, to participate in the Nato Summit on 14 June.
President Biden's trip will focus on "restoring our alliances" and "revitalising the Transatlantic relationship", the White House said.
During his time in the UK, Mr Biden is due to hold bilateral meetings with fellow G7 leaders, including Prime Minister Boris Johnson.
"This trip will highlight his commitment to restoring our alliances, revitalising the transatlantic relationship, and working in close cooperation with our allies and multilateral partners to address global challenges and better secure America's interests," the president's press secretary said.
The G7 summit is an opportunity to "reinforce our commitment to multilateralism, work to advance key US policy priorities on public health, economic recovery, and climate change, and demonstrate solidarity and shared values among major democracies," they added.
The UK, US, Germany, France, Canada, Italy and Japan make up the G7, while leaders from Australia, India, South Korea and the EU will also attend the summit as guests.
It will be held in Carbis Bay, near St Ives.
The US president's trip to the UK will be his first to any nation since defeating Donald Trump in November's election.
Following his victory, Mr Biden also chose to call the UK prime minister before any other European leader.
During that call, the two leaders talked about "the benefits of a potential free trade deal" between the UK and the US, with Mr Johnson reiterating his intention "to resolve existing trade issues as soon as possible", Downing Street said at the time.
Both Mr Johnson and Mr Biden have been taking part in a climate action summit - hosted by the US - this week.
The US has pledged to cut carbon emissions by 50-52% below 2005 levels by the year 2030.
This new target, which was unveiled at a virtual summit of 40 global leaders, essentially doubles their previous promise.
Earlier in the week, it was revealed that the UK hopes to cut its own carbon emissions by 78% by 2035.
