The G7 - the Group of Seven - is an organisation made up of Canada, France, Germany, Italy, Japan, the UK and the United States - the world's most advance economies. Every year the leaders meet to discuss the pressing issues of the moment and economic policies - and they try to work together to make big decisions on global events - like the pandemic. Presenter Max Towle and Worldwatch's Perlina Lau explain what it's about.
