The countdown has begun. The G20 Summit is returning to South America. Five years after Argentina's presidency in 2018, this year it is Brazil's turn, where meetings have already begun and will continue throughout the year, culminating on November 18 and 19 with the Leaders' Summit in Rio de Janeiro. The heads of state and government of the nineteen member countries are expected to participate, including Argentina, the European Union, and the African Union, as well as invited countries.
