Why did Belarus maintain close economic ties with Russia after the Soviet Union collapsed?

Following the collapse of the Soviet Union, Belarus maintained close economic ties with Russia primarily as a response to severe economic upheaval.1

During the Soviet era, Belarus developed a large industrial sector that was deeply integrated with and dependent on other Soviet republics—particularly Russia—for essential energy and raw materials. When the Soviet Union dissolved, Belarus faced a dual crisis: the cost of these necessary imports rose to world market levels, and its traditional markets for manufactured goods were significantly reduced.12

To mitigate the resulting decline in production, the Belarusian government sought to preserve its economic relationship with Russia. This strategy was further solidified under the leadership of Alexander Lukashenko, who favored maintaining a model of market socialism and pursued formal political and economic integration through the Union State. Because Belarus is poorly endowed with mineral resources, it remains heavily dependent on Russia for the vast majority of its fossil-fuel and energy requirements, reinforcing this long-standing economic partnership.13
