What countries are in the G-7 summit and what do they do? What you need to know for Biden's trip to Europe

President Joe Biden traveled to Europe on Wednesday on the first international trip of his presidency which coincides with the European Union's recent reopening of its borders to vaccinated tourists. 

During the eight-day tour, Biden will meet with Russian President Vladimir Putin, visit Queen Elizabeth II and attend the Group of Seven, or G-7, summit in Cornwall, England on June 11-13. It is the first time the summit has met in nearly two years and the first meeting in the post-Donald Trump era.
