In the current context, the Eurasian Economic Union (EAEU) faces the challenge of ensuring sustainable development and effective state regulation. One key issue is to foster coordination and cooperation among different regions and EAEU member states in the development of digital technologies. This study aims to propose directions for state regulation of digital technologies and their integration into a comprehensive mechanism for sustainable development and planning, within the concept of smart territories. We introduce the concept of smart territories as an outcome of sustainable development and planning, enabled by the adoption of digital technologies. Based on an expert survey, we identify key parameters for sustainable development and planning in smart territories, including stakeholder interests, modern challenges for territorial communities, and success factors. We conclude that the integration of digital technologies into smart territories can provide new standards for quality of life and economic development, while preserving the natural resources of these territories. Based on a balanced use of resources, our study highlights the need for a comprehensive strategy for the sustainable development of smart territories, addressing economic, social, and environmental issues.
