In Astana, the Eurasian Economic Union (EAEU) leaders will discuss Armenia's European Union (EU) membership plan in a narrow format and assess the risks associated with it, Russian presidential aide Yuri Ushakov said.

"Let me note that it is obvious [that] at the narrow format meeting, the leaders will discuss an issue outside the agenda, which concerns the Republic of Armenia's plans to join the European Union. Of course, an assessment will be made of the risks arising for the economic security of the EAEU member states in this regard," Ushakov said.
