The 20th Group of Twenty (G20) Summit, which spanned two days, concluded on Sunday in Johannesburg with world leaders reaching consensus on a wide-ranging declaration.
At the closing ceremony, South African President Cyril Ramaphosa highlighted the successful adoption of G20 South Africa Summit: Leaders' Declaration which demonstrates that world leaders' "shared goals outweigh our differences."
The 122-point declaration underscores the need to address global challenges through multilateral cooperation and calls for stronger support for developing countries to advance inclusive growth and sustainable development.
Ramaphosa emphasized that this was the first G20 summit ever held on the African continent and that South Africa has seized the opportunity of its presidency to ensure the priorities of Africa and the Global South were placed at the heart of the G20 agenda.
South Africa assumed the rotating G20 presidency on Dec 1, 2024, becoming the first African nation to hold the position. The United States is scheduled to take over the presidency on Dec. 1, 2025.

A documentary has revealed how generations of fishermen in south China's Hainan Province navigated the South China Sea for centuries with no GPS, no weather forecasts, relying only on a handwritten manual known as the Genglubu.
The documentary, Genglubu: Charting the South China Sea, premiered Thursday on China Global Television Network (CGTN).
Unintelligible to outsiders, the Genglubu was an invaluable navigational guide for fishermen and one of the most important items they carried on board.
"What Tanmen fisherman do is dive into the sea and catch fish ourselves. Finding better reefs means catching more fish. And that's why we keep going back to the South China Sea. My grandfather and father would study it like homework before setting out," said Wang Zhendong, curator of the Genglubu Museum in Hainan's Qionghai City.
Wang cannot personally interpret the old manuscript, but he understands its importance: his father studied it before every voyage, and his grandfather trusted it with his life.
"When electronic equipment fails, if you don't understand navigation, how are you going to bring everyone home safely? A captain needs to understand experience. So where does that experience come from? It comes from the Genglubu. It's the ancient knowledge recorded generation after generation," said Wang Shubao, Wang Zhendong's father.
Over generations, that knowledge was written down in the Genglubu.
"Geng" referred to both time and distance traveled at sea. One "geng" was about two hours of sailing, or roughly 10 nautical miles.
"Lu" referred to compass bearings and direction, while "bu" meant "book."
Without modern instruments, fishermen learned to read the sea -- its currents, its depths, its changing moods.
Knowledge shaped their navigation. The Genglubu recorded that knowledge.
One line in it says: From Tanmen port to the Xisha Islands' Zhaoshu (Paracel's Tree Island), follow the direction of the Qian, Sun, which is northwestward. It covers a distance of some 150 nautical miles.
Just a few lines, enough to guide a boat across open water.
One surviving manuscript, copied by Wang Shitao, records 279 routes, making it one of the most detailed versions of the Genglubu known today. Its routes link Hainan with island groups across the South China Sea, with some extending even farther.
"Before Zheng He's voyages (1405-1433) to the Western Seas, the fishermen had already been working these waters of the South China Sea," said Zhou Weimin, a professor at Hainan University.
Experts say the Genglubu is more than a practical guide to navigation; it is also a record of China’s maritime history, cultural heritage and the accumulated wisdom of a people shaped by the sea.
"The Genglubu is a navigation handbook born of experience accumulated through long-term practice. It forms an integral part of China's maritime system. It is a cultural legacy created by our ancestors and a crystallization of the wisdom of a people with a long maritime tradition," said Liu Yijie, a professor at the Center for Studies of Fujian and Taiwan at Fujian Normal University.
