NATO refutes Russia's accusations of militarization of the Western Balkans

While Moscow claims that the Western military alliance is militarizing the Western Balkans in order to confront Russia and that the West is undermining security in Bosnia and Herzegovina, opposing messages are coming from NATO and the European Union, emphasizing that the international presence in the country is aimed at maintaining stability, not creating conflicts.

However, NATO says they are noticing worrying trends in the Western Balkans, primarily secessionist threats in Bosnia and Herzegovina, the fragile security situation in Kosovo, and the stagnation in the process of normalizing relations between Kosovo and Serbia.

"Authoritarian countries like Russia seek to intervene and undermine democracies, exploiting internal weaknesses in the region to spread discord. Any external interference in internal democratic processes is unacceptable. This includes hacking, information threats, intimidation and other destabilizing activities," a NATO official told Radio Free Europe (RFE/RL).

Allegations of militarization and destabilization of the region were presented at a meeting of the Organization for Security and Cooperation in Europe (OSCE) in March, held in Vienna, where Russian representative Yulia Zhdanova stated that NATO's military and political activity in the Western Balkans region continues to cause deep concern.

The topic of the meeting was the implementation of the Arms Control Agreement, which stems from the Dayton Peace Agreement and refers to Bosnia and Herzegovina, Serbia, Croatia and Montenegro.

Zhdanova said that NATO's activities undermine the Dayton Agreement and directly Article 4 on arms control.

Contrary to Russia's claims, the European Union, in a joint statement after the OSCE meeting, emphasized that the Subregional Arms Control Agreement has been contributing to the stability of the region for three decades, especially in Bosnia and Herzegovina.

Unfounded Russian allegations

The Russian delegation during its speech in Vienna said that "the overall crisis nature of the internal political situation is determined by the destabilizing role of Western countries, which interfere in the affairs of sovereign Bosnia and Herzegovina, artificially inciting interethnic tensions."

Russia accused Western countries of wanting to destroy the "balanced system" established in Dayton, as well as of intending to reformat Bosnia and Herzegovina according to their standards, violating the interests of the peoples in this country.

Zhdanoa also blamed the high representative in Bosnia and Herzegovina, Christian Schmidt, for "destabilizing the situation," whom Russia considers illegitimate, as his appointment has not been confirmed by the United Nations Security Council, which was not even necessary.

The High Representative is appointed by the Peace Implementation Council (PIC) in Bosnia and Herzegovina, which is also the case with the current representative of the international community in Bosnia and Herzegovina, Schmidt.

"We are convinced of the necessity of the urgent and unconditional closure of the institution of the foreign protectorate in Bosnia and Herzegovina," said the Russian representative, blaming the West for the cessation of Russian funding of the PIC, as well as for its non-participation in the work of this institution.

For the closure of the Office of the High Representative, Bosnia and Herzegovina must meet 5+2 conditions and objectives, including the division of property between the state and other levels of government, the solution to military property, the implementation of the final decision on the Brcko District, the fiscal sustainability of Bosnia and Herzegovina, and the rule of law, conditions that the country has not yet met.

Military analyst Gjuro Kozar told REL that the Russian claims are unjustified.

"The security situation is negatively affected by the influence of Russian politics in Bosnia and Herzegovina, which is manifested through the destructive policy of the leadership of Republika Srpska towards the state of Bosnia and Herzegovina, led by the leader of the separatist option, the president of the SNSD, Milorad Dodik. In its efforts to disintegrate Bosnia and Herzegovina, the RS establishment has the support of Russia, which opposes Bosnia and Herzegovina's membership in NATO," said Kozar.

For Russia, the strengthening of EUFOR is also unfounded

In her speech, Zhdanova also said that Russia is closely following the progress of the operations of the European peacekeeping forces in Bosnia and Herzegovina (EUFOR).

"We warn that it is unacceptable to involve international forces in internal political processes. We consider that the increase in the number of EU forces is unfounded," she said during the speech.

In recent years, the number of EUFOR members has increased, mainly as a preventive measure following the rise in tensions in the country due to the adoption of unconstitutional and secessionist laws in the Republika Srpska entity, which were later repealed.

An official from NATO headquarters, who did not wish to be named, told REL that NATO continues to provide support to EUFOR, with the aim of preserving the territorial integrity, sovereignty and independence of Bosnia and Herzegovina.

"We fully respect the sovereign right of every state to independently choose its own political and security arrangements. This is a fundamental principle of European security, which all states, including Russia, have accepted," said this alliance official.

Military expert Kozar assessed that neither the presence of NATO headquarters nor that of EUFOR in Bosnia and Herzegovina implies militarization.

"The NATO headquarters has close to 100 people, mostly civilians, and their task is to help strengthen the Armed Forces of Bosnia and Herzegovina within the framework of NATO's Partnership for Peace, in which Bosnia and Herzegovina has been since 2006."

Kozar added that Moscow, through criticism of the strengthening of EUFOR, aims to withdraw the Office of the High Representative (OHR) from Bosnia and Herzegovina, "so that the separatist objectives of Republika Srpska can be realized."

What does the Arms Control Treaty include?

The agreement on subregional arms control, which was the focus of the Vienna meeting, was signed in 1996, under the mediation of the OSCE.

The agreement provides for precisely defined limitations on weapons, including tanks, armored combat vehicles, and artillery.

According to the European Union, the signatory states, including Bosnia and Herzegovina, have, during the years of implementation, reduced the amount of heavy weapons and the number of members of the armed forces below the levels envisaged by the agreement.

Since 2014, the signatory states have taken full responsibility for implementing the agreement, which the EU statement of March 2026 cites as an example of successful regional cooperation and confidence-building.

The joint declaration, which assesses the Agreement as "an exception at a time when most arms control agreements are not being implemented", was signed by, in addition to EU member states, Albania, Bosnia and Herzegovina, Georgia, Iceland, Liechtenstein, Montenegro, North Macedonia, Norway, the Republic of Moldova, San Marino, Serbia and Ukraine.

"June of this year marks 30 years of continuous and uninterrupted implementation of the Arms Control Agreement. As such, it has become a stable part of security policy in the region," the statement said.

NATO will not allow a security vacuum in the Western Balkans

NATO is clear that the Western Balkans remain "high on the agenda" and have strategic importance for the alliance.

"Our commitment to regional stability is strong and we will not allow a security vacuum to be created," an official told Radio Free Europe.

NATO's commitment to the Western Balkan countries is reflected in several activities.

Support for EUFOR and the Armed Forces of Bosnia and Herzegovina was mentioned earlier, while NATO also said that they are deepening political dialogue and practical cooperation with Bosnia and Herzegovina, "including through NATO Headquarters in Sarajevo, the Political Engagement Support Unit, as well as the newly approved individually tailored partnership program."

NATO also said that the longest and largest peacekeeping mission in the history of the alliance is in Kosovo, KFOR, which continues to contribute to a safe and stable environment for all people and communities living in Kosovo.

"KFOR's strength and deployment are reviewed and adjusted periodically, in accordance with evolving circumstances, so that the mission remains functional and fit for purpose. Currently, KFOR numbers close to 4.600 soldiers from 33 countries, including NATO allies and partner states," the alliance official said.

Russia, in its presentation at the OSCE meeting, said that in addition to the fact that “the trend of militarization has included the countries of the region that are members of the alliance,” with the instructions of NATO instructors, Kosovo's combat capabilities are actively increasing.

Moscow also sees the holding of exercises in the Western Balkan countries with NATO as a threat.

"The Alliance does not hide the fact that the Balkans as a whole, and especially its western part, is destined to become an important springboard within NATO's preparations for a direct military confrontation with our country within three to five years, for which Brussels is intensively preparing," Moscow claimed.

However, NATO emphasized that long-term partnerships with countries in the region, primarily with Serbia and Bosnia and Herzegovina, are based on political dialogue and practical cooperation.

"We will continue to advance dialogue and cooperation to support reforms, regional peace and security, and to counter malign influence, including disinformation and cyber threats coming from both state and non-state actors," the NATO official told REL.

US warns of Russia's malign influence in the Western Balkans

In the "Annual Threat Assessment 2026" report, US intelligence agencies warned that the Western Balkans remains an area of ​​heightened political tensions and external influences, highlighting Russia's role in destabilizing the region.

Russia, according to the report published on March 18, "foments instability between Serbia, which it favors, and Kosovo," but also "supports the secession of the Republika Srpska entity from Bosnia and Herzegovina."

American services assess that ethnic and political divisions in the region remain pronounced and pose a potential security risk, especially in combination with the influence of external actors.

The Western Balkans is described in the report as a space where the interests of great powers collide, while existing crises and unresolved disputes, including relations between Serbia and Kosovo, as well as internal political relations in Bosnia and Herzegovina, remain key sources of instability.
