Russian officials have stepped up pressure on Armenia to clarify its future foreign policy and integration direction, warning that continued efforts to deepen relations with the European Union while maintaining membership in Russian-led organisations could affect bilateral economic and security cooperation. The issue emerged as a central theme in statements by Russian Ambassador to Armenia Sergey Kopyrkin and Deputy Foreign Minister Alexander Pankin on 8-9 November, followed by Foreign Minister Sergey Lavrov's announcement on 10 November that the Collective Security Treaty Organization (CSTO) would consider suspending Armenia's voting rights over unpaid membership contributions. The developments come as Yerevan continues to distance itself from the CSTO, diversify its international partnerships and pursue closer relations with the EU, while retaining formal membership in both the CSTO and the Eurasian Economic Union (EAEU).

On 8 November, Kopyrkin that the changes in Armenia's foreign policy had created a new situation in bilateral relations that required finding a new balance. Kopyrkin specifically referred to Yerevan's decision to freeze its participation in the CSTO, its announced revision of the national security framework, the diversification of its foreign policy and economic ties, and the 2025 law initiating the process of seeking EU membership. "In fact, the coordinate system of our relations is changing. We approach it with understanding," the ambassador stated, adding that the new circumstances required a comprehensive assessment and adjustments to cooperation between the two countries. Kopyrkin stressed that Armenia's eventual integration choice would have significant implications for the nature and mechanisms of bilateral relations, including trade and economic cooperation. Kopyrkin reiterated Moscow's position that holding membership in the EAEU was in Armenia's interests, citing increased trade turnover with member states and economic growth. Although Kopyrkin acknowledged that the decision belonged exclusively to Armenia and its people, he signaled that Russia wanted Yerevan to clarify its position as soon as possible.

Kopyrkin also addressed the possibility of a meeting between Armenian Prime Minister Nikol Pashinyan and Russian President Vladimir Putin, saying that he was unaware of any preconditions for such an encounter. According to Kopyrkin, the initiative originated with the Armenian side and was intended to review the different areas of bilateral relations under the changed circumstances. Kopyrkin rejected suggestions that the meeting could be conditional on progress in negotiations concerning Russian Railways or Rosatom. The ambassador also defended Russian restrictions affecting certain Armenian products, denying that they constituted political pressure or sanctions. He maintained that the measures were based on objective factors and the assessments of inspection authorities, while describing the perceived connection between the restrictions and periods of political tension as subjective.

On economic cooperation, Kopyrkin recent meetings between Pashinyan and the heads of Russian state companies Rosatom and Russian Railways. Kopyrkin called discussions on the future of the South Caucasus Railway concession constructive and said the agreement, under which the Russian company manages Armenia's railway network, had been drawn up on exceptionally favourable, potentially unprecedented terms for the Armenian side. Kopyrkin also confirmed Moscow's readiness to continue cooperation in railway transport and nuclear energy. Asked whether possible concessions on railway management could be linked to Russian involvement in the construction of Armenia's new nuclear power plant, he declined to speculate, saying that the issues should be assessed comprehensively and managed through constructive negotiations based on mutual political will.

On 9 November, Deputy Foreign Minister Pankin declared that the possible suspension of the application of the EAEU Treaty to Armenia would depend on the steps taken by the Armenian authorities. Pankin the measure as an extreme option intended to prevent potential damage to the economic security of the union's other member states, claiming that Moscow had not received constructive signals from Yerevan addressing their concerns. Russian diplomat also criticised Armenia's European integration policy, arguing that the economic benefits Yerevan receives through EAEU membership were being used to promote the country's possible accession to another integration bloc. Pankin called for a nationwide referendum on Armenia's future integration direction before the submission of an official EU membership application, arguing that the opposite sequence would effectively deprive the population of the opportunity to make a genuine choice. He also accused the Armenian authorities of attempting to shift responsibility for their decisions onto other CSTO member states, noting that Armenia remained a full member of the organisation despite freezing its participation and failing to pay contributions.

Tensions over Armenia's position within the CSTO escalated further on 10 November, when Lavrov that the organisation's member states would consider a draft decision suspending Armenia's voting rights and its ability to nominate citizens for quota-based positions within CSTO bodies. Speaking after a joint meeting in Moscow of the CSTO Council of Foreign Ministers, the Council of Defence Ministers, and the Committee of Secretaries of Security Councils, Lavrov confirmed that CSTO member states had discussed Armenia's failure to fulfil its financial obligations since 2024, resulting in arrears exceeding two years. Lavrov cited Article 25 of the CSTO Charter, which provides for the suspension of voting rights and quota-based appointments when a member state fails to meet its financial obligations for the prescribed period. Armenia did not participate in the 10 November ministerial meetings.

In Lavrov’s view, the proposed restrictions According to Lavrov, even if the decision were adopted, Armenia would retain the fundamental rights provided under the Collective Security Treaty, including the right to collective security. Lavrov also confirmed that Moscow had received no official application from Yerevan to withdraw from either the CSTO or the EAEU and insisted that Russia did not intend to expel Armenia from the military alliance. The Russian foreign minister argued that if Yerevan considered the organisation no longer compatible with its security interests, it should make its own decision on withdrawal rather than expect other member states to terminate its membership. Separately, CIS Secretary General Sergey Lebedev further that Armenia had not announced any intention or plan to withdraw from the Commonwealth of Independent States (CIS). Lebedev noted that Pashinyan had personally assured him, as had other Armenian representatives, that the country intended to remain in the organisation.

The forthcoming CSTO summit and the three-month review of the Russian railway concession will be important in determining the immediate direction of cooperation between Yerevan and Moscow, particularly as Armenia continues to balance its economic ties with Russia against its efforts to diversify its security and foreign policy partnerships.
