French President Emmanuel Macron told world leaders gathering in Bali that Paris "supports the full and complete integration of the African Union into the G20", in the same way as the European Union is a member.
"If we want to express real solidarity with the South, we must accept that the African Union, like the European Union, comes to the table," Macron declared during a press conference on Wednesday.
South Africa is currently the only African member of the G20.
Senegalese President Macky Sall, who heads the African Union, has previously called for an overhaul of international governance, and urged greater African representation on bodies such as the UN Security Council and the G20.
In October, Sall said multilateralism had to "serve the interests of all" or else risk the "loss of legitimacy and authority."
Both Sall and South Africa's president Cyril Ramaphosa were in attendance at the G20 leaders' summit this week.
The French president also announced he will hold an international conference in June on a new financial pact with the South, insisting that "we must not ask these countries to support multilateralism if it is not able to respond to their vital emergencies".
Special drawing rights
This will include taking stock of the reallocation of International Monetary Fund (IMF) special drawing rights (SDR) from rich countries to poorer countries.
France has made a commitment, with a few other countries, to be able to reallocate 30 percent of "special drawing rights" to "the most fragile countries".
