The presidency of the Republic of Belarus in the Commonwealth of Independent States, which aims to implement the long-term elements of the development strategy of this integration association in the post-Soviet space, will come to an end in 2022. The measures taken in 2021 under the auspices of Belarus' presidency, combined with the efforts of the states at the national level, made it possible to ensure the growth of the most important macroeconomic indicators. The achievement of positive dynamics is largely facilitated by the Commonwealth's free trade zone for goods, which provides favorable conditions for the development of the countries' economies. In 2021, thanks to Belarus' chairmanship in this international organization, active work on the draft agreement on free trade in services, which is designed to provide additional opportunities for sustainable economic development in the post-Soviet space, was continued together with other states. The result here should be the signing of the document in May 2022. These facts show that Belarus is seriously committed to the development of cooperation with partners, both in the post-Soviet space and other vectors.
