Protection of the rights of foreign investments and investors, improvement of legal documents for their registration, and determination of prospects in a market economy are one of the urgent tasks of our time. The reforms consistently carried out by our state in the social and economic spheres are yielding positive results.

Despite the ongoing reforms, the analysis shows that foreign investors do not have full rights to carry out their activities, the mechanism for their implementation is not sufficiently developed, and the presence of certain obstacles, including conflicting norms in the legislation, indicates the need to explore this area. This article analyzes the interpretation of the concept of “foreign investment” in our national legislation and the attitude of scientists toward this concept.
