According to the famous French politician and diplomat of the 18th - 19th centuries Charles Maurice de Talleyrand-Perigord, in politics "there are no principles, there are only events". The events of the contemporary circumstances around the world make economic integration necessary, regardless of the political games and preferences, with the purpose of forming a competitive donEstic market in the global system of international relations, as well as with the purpose of creating opportunities for the economic growth and for an effectively functioning national economy. The main purpose of this research is to reflect on the actual economic activity of the foreign companies that place their manufacturing facilities in Russia starting from the time when sanction limitations were imposed. For that matter, the investment activity of foreign companies on the Russian market has been analyzed starting in 2014. It is starting from this period specifically that the international mass media have been mentioning a certain drop of investment activity on the side of foreign parties. The authors of the present paper have performed an analysis of the most lucrative economic sectors that have been the focus of foreign participants' financial interests. Companies whose manufacturing activity has been completely localized in Russia have been chosen out for the purposes of this research. Special attention has been given to the companies that have continued their investment activity in the regions of Russia after the deterioration of the geopolitical situation in 2014. The practical part of the present paper is based on the data provided by the Russian Direct Investment Fund, Russian Federal State Statistics Service as well as by foreign companies working in Russia. This paper presents and proves the attractiveness of the Russian market for foreign investors, which has been illustrated by specific cases of deals that have been closed.
