US President Joe Biden arrived here on Thursday ahead of this weekend's G7 summit.
Notably, this is Mr Biden's first overseas trip since he assumed the office of President of United States.
Over the next eight days, Biden will meet with G7, NATO and EU counterparts in the UK and Belgium and have a summit with Russia’s President Vladimir Putin in Switzerland.
Downing Street in a statement said Prime Minister Boris Johnson and Mr Biden are expected to agree to work on resuming travel between their two countries.
Biden and Johnson will meet in Cornwall for the first time later on Thursday. The two leaders are also expected to agree on a landmark technology agreement, the release added.
