In the introductory part of the article, the importance of foreign direct investments for host states are examined. Following this, non-commercial risks foreign investors are facing in the host state (e.g. taking, currency inconvertibility risk, etc.) are assessed and finally, legal instruments for the protection of these investments are considered. Legal instruments for the protection of foreign investments can be divided into domestic (host state) and international instruments. Foreign investors usually prefer international instrument as these insure impartial dispute settlement. These are individual agreements between the investor and the host country (in which the host country agrees to treat the investor equal), bilateral investment treaties (BIT) and multilateral agreements.
