G7 - the "Group of Seven" countries - came together in 1975 as the seven most important industrialized nations at the time.
These seven countries are the US, the UK, France, Germany, Italy, Japan and Canada. In 1998 Russia was added and the group expanded to G8, before it was excluded again in 2014 after Russia's annexation of the Crimean peninsula.
US President Joe Biden has raised concerns over the jailing of Kremlin critic Alexei Navalny in his first phone call with Vladimir Putin. All G7 foreign ministers condemned Navalny's arrest as "politically motivated."
