OBS_VALUE: As a base rule, foreign providers of services in the RF are eligible to national treatment. However, relevant foreign investment can be limited due to national security considerations. The law takes a broad definition of national security by encompassing, in particular, defence and protection of the State, protection of integrity and stability of its financial system, currency control or maintaining the balance of payments of the RF. Possible measures cannot discriminate against States that concluded reciprocity agreements with the RF, and thus can discriminate States that do not have relevant reciprocity agreements. The RF authorities monitor the foreign trade activities for national economic security reasons. Also, foreign control over entities of strategic importance, including entities operating in sectors considered to be natural monopolies, requires prior approval of the state authorities.
