In the African Union, there are 55 member countries, and it works towards their social and economic development.

Under the leadership of the leaders, on Sunday, the group officially named G20 or J21. This change happened after the African Union (AU) was included as a permanent member of G20 on Saturday.

Official sources have said that the formal announcement of changing the name of the International Economic Forum has not been made yet, but it is expected to be announced on September 10th, according to the latest announcement.

The G20 leaders' summit is currently taking place in the capital city. The leaders' announcement is expected to take place on the afternoon of September 10th.

So far, G20 included 19 countries: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, United Kingdom, and the United States, along with the European Union.

The inclusion of the African Union (AU) in G20 is seen as one of its most significant expansions, with hopes of boosting global south representation in international economic matters.

G20, comprising some of the world's largest economies, was established in 1999 as a part of the international response to the Asian financial crisis, to address global economic issues involving finance ministers and central bank governors. After the global financial crisis in 2007, it was elevated to the level of heads of state.
