What does does the G in G-20 mean?

The "G" in G-20 stands for "Group." The G-20, or Group of Twenty, is a forum for international economic cooperation that brings together 19 countries and the European Union. It was established to address global economic challenges and promote financial stability, particularly in the wake of the 2008 financial crisis. The member countries represent about two-thirds of the world's population and 85% of global GDP.
