Increasing sanctions pressure on Russia and the need to implement the Presidential Decree оn the National Development Goals of the Russian Federation through 2030 (July 21, 2020, No 474) determines the urgency of the search for effective tools encouraging real growth of fixed investment up to at least 25% GDP. One such instrument could be the Investment Protection and Promotion Agreement (IPPA) allowing private business to stabilize the business environment, which is especially important under conditions of growing uncertainty, when predictability becomes the rarest and most demanded resource. The purpose of the study is to analyze a tool designed to stimulate the implementation of investment projects on the territory of Russia – IPPA. The methodology of the study includes comparative, systematic and informative analysis. The main finding is that, despite some limitations, IPPA is a potentially effective tool to support the implementation of private investment projects under conditions of import substitution, helping to restart the investment cycle and attract «long-term» money to the real sector of the national economy
