Biden is at the G7 meeting of world leaders. Here's what to know about it

(CNN) President Joe Biden's first trip abroad since taking office includes a G7 summit where he'll look to reestablish US leadership on the world stage.

Here's what you need to know:What is the G7?
The G7 is shorthand for Group of Seven, an organization of leaders from some of the world's largest economies: Canada, France, Germany, Italy, Japan, the United Kingdom and the US.
Russia was indefinitely suspended from the group -- which was at the time known as the G8 -- in 2014 after the majority of member countries allied against its annexation of Crimea.
It was the first violation of a European country's borders since World War II.
