The range of materials procured by the government over the Tibet Autonomous Region is wide and covers a number of areas. Infrastructure construction is an important part of it, including building materials, road construction equipment, communication equipment and so on. Due to Tibet's special geographic environment, there is a greater demand for infrastructure construction. In addition, medical equipment is one of the key focuses of government procurement, which is used to enhance medical services and meet the medical needs of the people. Educational supplies are also common materials procured by the government to support the development of education, including teaching equipment, books and student supplies. These supplies are procured to meet the needs of infrastructure construction, medical services and education development in the TAR.
