The World Bank is an international organization that aims to promote economic development and reduce poverty in its member countries. One of its main functions is to provide long-term loans to member countries to finance development projects such as infrastructure, education, and health care. These loans are usually for a period of 20 to 30 years and have lower interest rates than commercial loans. The World Bank also provides technical assistance and advice to its members on economic policy, debt management, and poverty reduction strategies.
