The products that occupy the largest share in the country’s exports to the group have been identified, which is a prerequisite for the establishment of joint ventures and can help increase their competitiveness. It was found that the group’s exports increased more than the world, and the main exporters continue to remain so. The growth of intra-regional and total imports of the group was revealed, its structure was analysed. It is determined that the trade balance of most countries was mostly negative.
