The system of measures of public support for production of export-oriented agricultural products in Kazakhstan and the EAEU member States is considered, directions for its improvement are determined. Indicators of production of gross domestic product, gross agricultural output, the share of crop production industry in it on average for 2015-2019 are presented. The prospects for export of domestic food have been studied; for this purpose, it is necessary to strengthen agricultural specialization of each industry. The authors note that phytosanitary measures are currently not regulated, there is no unified method for calculating the level of support, unified requirements for obtaining breeding products, a unified procedure for animal identification, unified rules for laboratory research and veterinary control. It is required to systematize and harmonize the existing tools and mechanisms for the development of the branches of agroindustrial complex of the republic in order to form a single market for the States of the Eurasian Economic Union, as well as develop sectoral programs. The article substantiates the need for systematic public support for the development of agro-industrial complex, aimed at meeting the needs of the domestic market and the implementation of centralized policy to promote exports. It is shown that environmental friendliness is one of the main competitive advantages of food products in the republic, contributing to the strengthening of Kazakhstan's positions on external sales market. The structure of exports of Kazakhstani agricultural products should be focused on reducing the share of raw materials in favor of agricultural products with high added value. In industries with high export potential, large specialized commodity zones and optimal flows of goods will be formed in order to ensure the country's food security..
