In the context of economic challenges and sanctions restrictions, multi-vector foreign trade and development of new segments of the world market remain a priority task of the state foreign economic policy of the Republic of Belarus. Asian countries, characterized by a large population, growing demand for these products against the background of an insufficient level of self-sufficiency, diverse taste preferences of consumers, as well as an increase in their purchasing power, are considered as one of the directions for the geographic expansion of exports of agri-food products. Under conditions of the unstable general economic and agrarian situation on the continent, Vietnam, Iran, China, and Singapore are our country’s key trading partners among Asian countries. This requires a comprehensive study to determine the further interaction of these countries with the Republic of Belarus. Scientific results are presented, including the justification of customs-and-tariff and non-tariff conditions for access to the markets of Vietnam, Iran, China, and Singapore, as well as a developed set of effective ways for promoting Belarusian agri-food products on the territory of these states. In addition, a forecast of export supplies of domestic products was carried out, taking into account the specifics of trade policy and trade and economic cooperation between the Republic of Belarus as a member state of the Eurasian Economic Union and the Asian countries under study. Practical implementation of the results obtained will allow Belarusian exporters to create competitive advantages based on the application of preferential terms of trade, increasing the efficiency of financial and non-financial instruments, expanding organizations’ access to support mechanisms, development of agricultural commodity distribution network, introduction of information, communication and digital tools for sales and marketing policies.
