The World Bank, short for the World Bank Group and the International Bank for Reconstruction and Development, is a specialized agency of the United Nations.
The World Bank was established in 1945 and began operations in June 1946. It consists of five member institutions: the International Bank for Reconstruction and Development, the International Development Association, the International Finance Corporation, the Multilateral Investment Guarantee Agency, and the International Centre for Settlement of Investment Disputes.
The International Monetary Fund, the World Bank, and the World Trade Organization—these three major international economic organizations are known as the three pillars of the global economy and together constitute a vital force driving global economic development.

Founding and Development History
The World Bank, established in 1945, is a key member of the international financial institutions dedicated to global poverty reduction and development. Headquartered in Washington, D.C., the United States, it currently has 188 member countries. It was founded in Bretton Woods, New Hampshire, USA. The World Bank is one of the international financial institutions dedicated to promoting global poverty reduction and development. At its inception, its primary operations included loan projects and non-loan assistance, providing financial and technical support to member countries to facilitate their development.
Purpose and Objectives
The World Bank's purpose is to provide loans and investments to member countries and promote the balanced development of international trade.
Purpose and Principles
According to the Articles of Agreement of the International Bank for Reconstruction and Development, the purposes of the World Bank are:
- To assist member countries in the economic reconstruction and development of their economies through investment in productive enterprises, and to encourage the development of resources in underdeveloped countries;
- To promote private investment abroad by guaranteeing or participating in private loans and other private investments. When member countries are unable to obtain private capital under reasonable conditions, they may use the Bank's own capital or funds raised to supplement the shortfall in private investment;
- To encourage international investment, assist member countries in improving their production capacity, and promote the balanced development of their international trade and the improvement of their balance of payments;
- When providing loan guarantees, they should coordinate with other international lending sources.
In its early years, the World Bank primarily provided financial assistance to Western European countries to recover from the war. However, after 1948, European countries began to rely primarily on the US Marshall Plan for post-war economic recovery. The World Bank then shifted its focus to providing medium- and long-term loans and investments to developing countries, promoting their economic and social development.
The World Bank strives to narrow this gap, transforming the resources of rich countries into economic growth in poor ones. As one of the world's largest providers of development aid, the World Bank supports developing country governments in their efforts to build schools and hospitals, provide water and electricity, prevent and treat diseases, and protect the environment.

World Bank Loan Types:
- Project Loans: This is the World Bank's most mainstream and traditional lending method, accounting for over 90% of its total lending and primarily used for infrastructure development in member countries.
- Non-project Loans: These are primarily used by member countries to import supplies and equipment, respond to emergencies, and adjust economic structures.
- Technical Assistance Loans: These include technical assistance related to specific projects and "stand-alone technical assistance" not related to projects.
- Syndicated Loans: These are loans led by the World Bank in collaboration with other lending institutions.
- Third Window Loans: These are a third type of loan, in addition to World Bank general loans and IDA concessional loans, primarily intended for low-income developing countries.
