The Group of 77, or G77, is a coalition of developing countries established in 1964 to promote their collective economic interests and enhance their negotiating power in international forums. Initially formed by 77 nations, the group has since expanded to include over 130 member states, representing a significant portion of the global population. The G77 focuses on issues such as trade, development, and climate change, advocating for fairer economic policies and greater support from developed nations. It plays a crucial role in organizations like the United Nations and aims to address the challenges faced by developing countries in a rapidly changing world.
