Abstract: The subject of the article is strategic approaches to the development of partner financing in Russia and the CIS countries. The object of the study is the steps taken by scientists, practitioners, specialists and the government so that Russian partner financing organizations could integrate into the Eastern international markets in the best and most effective way. The purpose of the study is to identify the challenges and opportunities that open up for Russia and the CIS countries in connection with the implementation of the principles and rules of partner financing in economic phenomena. The study is conducted in the context of the CIS countries: Russia, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan. Using the methods of analysis and synthesis, comparison and contrast, scientific analysis, the article examines the current state of partner financing activities in Russia, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan. Based on the results of the study, the article concludes that among the CIS countries that are members of the Organization of Islamic Cooperation, the most developed system of Islamic banking is in Kazakhstan, Kyrgyzstan and Tajikistan. However, in these countries, despite the widespread use of both Islamic banks themselves or individual Islamic products, and a fairly developed legislative and practical framework, there are still many unresolved problems of implementing Islamic economic principles. The Islamic Development Bank plays a huge role in solving these problems in these countries. Many issues of the theory and practice of partner financing remain undisclosed, since the topic of partner financing is quite new for the countries under consideration, for example, for Russian reality, the federal law on partner financing was put into effect only in 2023. In addition, the study allowed us to conclude that it is important to amend tax legislation, legislation on self-regulatory organizations, non-credit financial organizations and insurance.
