ووفقا لبيانات الجمارك الصينية ، تنزانيا imported gantry cranes from China in 2021 with a value of US $545000, compared with us $2015000 in 2020. In terms of import quantity, Tanzania imported 9 sets of gantry cranes from China in 2021, with an average import price of US $60000. In 2020, it imported 14 sets of gantry cranes, with an average import price of US $143900. In terms of import quantity and amount, Tanzania's gantry crane market has shown a certain degree of decline, which is not good news for Chinese crane suppliers to further open the Tanzanian crane market. At the macro level, trade between China and Tanzania is closer. In 2021, the bilateral import and export volume of goods between China and Tanzania was US $6744.52 million, an increase of US $2160.7358 million over the same period in 2020, a year-on-year increase of 47.1%. Perhaps Tanzania's gantry crane market still has bright prospects in the future
