UNCTAD (United Nations Conference on Trade and Development) uses the term "Emerging Economies" to refer to countries that are undergoing significant economic growth and transformation, but which are not yet fully developed or industrialized. These economies are often characterized by rapid industrialization, increasing urbanization, and a growing middle class.

Brazil, Mexico, and South Africa are all examples of countries that fall within this category. They are all large and diverse economies that have shown strong growth in recent years, and they are also home to significant natural resources and skilled workforces.

UNCTAD tracks and analyzes the development of emerging economies, and works to support policies and programs that can help these countries achieve sustainable and inclusive economic growth. By identifying and promoting opportunities for trade, investment, and development, UNCTAD aims to help emerging economies build the infrastructure and capabilities needed to compete and thrive in the global economy.
