Economic sovereignty has become a critical priority for nations facing external sanctions. Russia, a major global energy exporter, has experienced escalating Western sanctions since 2014, particularly after the 2022 Ukraine conflict, which targeted its financial systems, technology access, and energy trade.

The agricultural sector and domestic payment systems are highlighted as key areas demonstrating Russia's shift toward self-reliance. While short-term stabilization has been achieved through capital controls and energy exports, long-term challenges persist in overcoming technological dependencies and fostering non-resource industrial competitiveness.
