The full name of Tanzania: United Republic of Tanzania. Located in eastern Africa, south of the equator. A member of the Commonwealth of Nations. It borders Kenya and Uganda to the north, Zambia, Malawi, and Mozambique to the south, Rwanda, Burundi, and Congo (DRC) to the west, and the Indian Ocean to the east. It has a land area of ??945,087 square kilometers and a total population of 44.9 million as of 2013.

Tanzania is one of the least developed countries in the world declared by the United Nations. The economy is dominated by agriculture, and food is basically self-sufficient in ordinary years. Industrial production technology is low, and daily consumer goods must be imported.

In 1967, nationalization and planned economy were implemented, and the "Ujamaa" socialist movement was launched with the construction of collective farms as the center, which was seriously out of touch with the national conditions, resulting in serious economic development lagging behind. Since 1986, it has accepted the adjustment plans of the International Monetary Fund (IMF) and the World Bank, and implemented the "Three-Year Economic Recovery Plan" three times in a row.
