Abstract: This article discusses aspects of solving environmental protection problems and outlines issues characterizing the interaction between the Russian Federation and the People's Republic of China. An assessment is given on the adoption of legislation for both states and joint coordinated measures aimed at reducing and eliminating negative trends associated with environmental degradation in Russia and China. The features of the Russian Federation and the People's Republic of China's influence on state environmental policies on environmental issues are described. The analysis of the state of legality in enforcing environmental legislation and the effectiveness of legal means used in implementing prosecutorial supervision in this area is carried out. Empirical, statistical, and scientific information is provided on how the prosecutor's offices of the Russian Federation and the People's Republic of China participate in the formation of methods and tools of national environmental policies that are of a state nature and carry out their activities mainly in legal forms using complex mechanisms of legal regulation. The proposed article compares the concepts of sustainable development in force in Russia and the People's Republic of China based on generally recognized environmental standards by the international community, which have been ratified in the legislation of the countries under consideration, and analyzes the problems and areas of improvement of Russian and Chinese environmental legislation.
