Abstract: Tanzania, located in the southeast of Africa, is the bridgehead of the "the Belt and Road" in Africa. It is also a pilot country for China's industrial cooperation and production capacity cooperation with Africa. On the basis of studying the general situation of mineral resources and the current situation of mining development in Tanzania, this paper analyzes the prospect of Chinese enterprises' mining investment in Tanzania from the aspects of political stability and financial environment. The research shows that Tanzania is rich in mineral resources, with great potential for mining development, stable political situation and good financial environment. Especially since the new President Hassan took office, many favorable information of investment environment has been transmitted. Although there are unfavorable factors such as backward infrastructure, lack of basic geological data and government corruption, the author believes that investors can start from the gold mine with rich resources and good development foundation, and take the opportunity to invest in graphite, rare earth and other minerals with great potential. At the same time, it pays attention to the upstream and downstream integrated industry chain operation mode of mining exploration, mining, beneficiation and smelting, and makes overall layout to drive local economic development.
