Armenia prepares formal European Union bid as Nikol Pashinyan weighs exit from Russian-led CSTO

Membership proposal and diplomatic shift

Armenian Prime Minister Nikol Pashinyan addressed the parliament in Yerevan on Monday, 24 August 2026, to introduce the official government program for the 2026–2031 legislative term. During his parliamentary address, Pashinyan announced that the executive branch is preparing to submit a formal application for European Union membership in the near future. The policy move reflects Yerevan's sustained strategy to deepen institutional ties with Western partners while steadily disengaging from Moscow. Russian leadership views the former Soviet republic in the South Caucasus as part of its traditional sphere of influence and strongly opposes Yerevan's westward pivot. Pashinyan told lawmakers that formal submission of accession paperwork must occur before any national referendum on European integration can realistically take place.

The Eurasian Economic Union referendum dispute

In May 2026, the heads of state of Russia, Belarus, Kazakhstan, and Kyrgyzstan formally insisted that Armenia hold a nationwide referendum to choose between European Union accession and remaining within the Eurasian Economic Union. The Kremlin maintains that participation in the European bloc is mutually incompatible with Armenia's continued membership in the regional Eurasian economic alliance. Russian President Vladimir Putin raised this demand directly prior to Armenia's early summer elections, pressing Pashinyan to make an immediate choice between the two economic structures. Pashinyan countered that holding a referendum makes sense only when the Armenian state can accurately evaluate the feasibility and specific terms of European membership.

We could initiate this process in the near future, especially given the urgent demands of our partners in the Eurasian Economic Union.

Security estrangement and CSTO rift

Although Armenia and Russia remain formal military allies under existing agreements, relations deteriorated after the 2023 Azerbaijani military offensive in Nagorno-Karabakh. The Armenian government repeatedly criticized Moscow for failing to fulfill its mutual defense obligations during the 2023 conflict, prompting Yerevan to seek diplomatic goodwill from Brussels and Washington. In the aftermath of the fighting, Yerevan froze its operational participation in the Collective Security Treaty Organization, a post-Soviet regional defense alliance established in 2002 alongside Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, and Russia. Pashinyan declared on Monday that an official decision by the alliance to expel Armenia would be an acceptable outcome for his government.

I would be very happy if the organization decided to exclude Armenia from the CSTO. This would relieve us of the dilemma to leave or not to leave.

Retaliatory economic measures and election results

The political rift between Yerevan and Moscow triggered Russian trade restrictions and economic retaliation against Armenia. Russian authorities enacted import bans targeting Armenian agricultural goods, cutting off access to a key commercial market for Armenian growers. Russian officials also issued warnings regarding potential increases in bilateral natural gas tariffs and halted several bilateral trade exchanges. These economic measures coincided with Russian interference efforts ahead of Armenia's parliamentary elections on 7 June 2026. Despite extensive pressure from Moscow, Pashinyan's political party secured an absolute majority in parliament, allowing the administration to continue developing diplomatic, security, and economic cooperation with both the European Union and the United States.
