Asian Infrastructure Investment Bank is called Asian Infrastructure Investment Bank in English, referred to as AIIB. AIIB is an international multilateral development bank headquartered in Beijing, aiming at promoting infrastructure construction and economic development in this region. TPT is an index of AIIB, which is called the total project cost. This indicator reflects the total cost of AIIB investment projects.

As an important indicator, TPT plays an important role in the decision-making process of AIIB. Through the calculation of TPT, AIIB can better evaluate the risk and feasibility of its investment projects. At the same time, TPT is also an important reference for the loan amount of AIIB, and its level directly affects the amount of funds and projects that AIIB can provide.

The TPT index of AIIB is mainly applicable to infrastructure projects, such as roads, bridges, electricity, water and other fields. In these aspects, TPT can well reflect the total cost of the project, and give a clear cost calculation and risk assessment for the loan of AIIB. Of course, the application of TPT is also feasible and necessary in other fields, so AIIB is also actively exploring its application in other fields.
