Armenia cannot simultaneously join the European Union (EU) and remain in the Eurasian Economic Union (EAEU), since concurrent membership in these two organizations is incompatible. Valentina Matvienko, Speaker of the Federation Council of the Russian Federal Assembly, stated this in response to a question from TASS.

"Of course, it is incompatible. Participation in, the aspiration to join the European Union, and the launch of the [respective] membership process, so to speak, the European unification of the entire legal and normative base, are incompatible with membership in the Eurasian Economic Union. And all leaders openly and honestly say about this, that in that case, a choice must be made. We would also like it to be, of course, the choice of the Armenian people," Matvienko told reporters.
