BACKGROUND: The level of interest in Turkic cooperation has diverged over time and among the Turkic states. Some, like Kazakhstan and Azerbaijan, have consistently been enthusiastic participants. Türkiye, Turkmenistan, and Uzbekistan, on the other hand, have seen fluctuations in their enthusiasm. It is mainly in the last 7 to 8 years that a consensus has developed on the importance of Turkic cooperation.
Kazakh President Nursultan Nazarbayev in the late 2000s proposed the creation of a Council of Turkic-speaking States, which was formed in 2009. Twelve years later, it was turned into a formal inter-state organization, the Organization of Turkic States (OTS).
Up until recently, the intensification of cooperation among Turkic states was focused on non-security areas. Still, the OTS provided a platform where individual member states developed dialogue on security issues in both bilateral and trilateral formats. Thus, in parallel with the intensification of OTS activities, there has been a parallel rise in security, intelligence, and defense agreements among members of the organization.
Two types of formats can be seen in the growing security cooperation within the Turkic world. A first, not surprisingly, involves Türkiye’s bilateral security ties with other Turkic states. Importantly, however, a second format involves cooperation among those other states themselves, without Turkish participation.
The first type of format involves the growing Turkish engagement with Azerbaijan and the Turkic states of Central Asia. A key step was the formation of a defense treaty between Türkiye and Azerbaijan in the shape of the Shusha Declaration of June 2021, the same year OTS was created. The Shusha Declaration followed on the decisive role of Türkiye in supporting Azerbaijan in the 2020 Second Karabakh War. That, in turn, followed upon Türkiye’s active involvement in conflicts in Syria and Libya, where Ankara actively sided against Moscow-supported proxy forces; had a decisive impact on the outcome of the conflict; and managed to do so while maintaining a functional, if transactional, relationship with Moscow. There is no question that this was duly noted in Central Asian capitals and made a security and defense relationship with Türkiye increasingly attractive for the Turkic states of Central Asia.
In fact, Türkiye stands out among external powers in the region as it has shown a willingness and ability to engage across the spheres of security, intelligence, and defense (where Europe and the U.S. have generally been absent, with the notable exception of NATO’s Partnership for Peace program). As Richard Outzen put it, all Turkic states of Central Asia are at one point or another in the process of developing “military education exchanges, training and exercises, a broader range of equipment and defense technologies, and, perhaps most importantly, development of common doctrine and operational approaches” with Türkiye.
While Azerbaijan has reached the level of near-complete integration with Türkiye, other states are at less advanced stages of the process. They may not desire the same level of military integration with Türkiye as Azerbaijan does, but all are intensifying exchanges with Ankara. Kazakhstan began to expand military ties with Türkiye in 2020 when it signed an agreement for joint defense and industrial projects. That was followed by a protocol for intelligence cooperation in 2022, as well as an enhanced strategic partnership. Kazakhstan purchased Turkish UAVs and now holds a license to produce them in Kazakhstan.
Uzbekistan also started its process of deepening military ties with Türkiye. In 2022, the two countries signed a defense cooperation agreement on intelligence cooperation, as well as training and logistics. In November of that year, a further agreement included military education and defense industrial cooperation. As for Kyrgyzstan, it has purchased several types of Turkish UAVs, including TB-2 Bayraktar drones. Turkmenistan has also purchased Bayraktar drones. In late December 2023, Turkmenistan’s top leadership welcomed leaders of Türkiye’s largest defense industrial companies and publicly spoke of the potential role of these firms – and Türkiye – in helping Turkmenistan strengthen its defense capabilities.
As noted, not all security and defense cooperation involves Türkiye. On a bilateral level, security and defense cooperation has grown rapidly involving Kazakhstan and Uzbekistan, Azerbaijan and Kazakhstan, and most recently Azerbaijan and Uzbekistan. These three states have all raised their respective sets of bilateral relations to the level of allied relations, including through the formation of “Supreme Interstate Councils” for inter-state coordination on a government level. In the defense sphere, cooperation has developed through military exchanges, joint exercises, intelligence sharing, and the development of the defense industry.
Until recently, it was obvious that the development of Turkic Cooperation under the Organization of Turkic States served as a catalyst for the myriad of bilateral agreements in the security and military field. Yet formally, while OTS member states have discussed holding security consultations and developing a common stance on security issues ever since the Turkic Council’s Almaty Summit in 2011, defense and security cooperation remained outside the purview of the OTS. This has nevertheless begun to change as the OTS has more recently taken steps to expand into the security field.
IMPLICATIONS: The OTS’s organizational move into the field of security and defense dates to the summit in Samarkand in 2022. The member states “went beyond consultations by adding a new dimension to their security cooperation … they called for closer cooperation and military collaboration in the defense industry.”
Similarly, at the following summit in Astana in November 2023, the final communiqué called for “closer cooperation in the field of defense industry and military collaboration.” At the summit, a key advocate for the intensification of military cooperation was Azerbaijani President Ilham Aliyev, who stressed during his speech that “the main guarantor of security becomes defense potential” in the developing security situation and that he “believe[s] that cooperation between the member states in areas such as security, defense, and the defense industry should be further increased.” Following his re-election in 2024, Aliyev subsequently declared that the OTS was the main vector in Azerbaijani foreign policy.
The eleventh summit in Kyrgyzstan in 2024 focused on the adoption of a “Charter for the Turkic World” which did not specifically go into matters relating to security and defense. Still, a seed was planted: the charter includes language that “the Turkic people will strive together to prevent any actions and threats aimed at undermining their unity, solidarity, and dignity.” While far from a mutual defense clause, it is reminiscent of how the EU adopted a solidarity clause before moving to the mutual defense clause adopted with the EU’s Lisbon treaty. At this summit as well, Aliyev repeated his earlier call, saying, “Given the growing global threats, our cooperation in defense, security, and the defense industry is of tremendous importance.”
In July 2025, the first meeting of the heads of defense industries of the Turkic states was held in Istanbul, under the banner of the OTS. The meeting mainly served to take stock of existing bilateral cooperation programs and to plan for multilateral cooperation in the future. Azerbaijan has offered to host a second meeting in 2026.
The 2025 OTS Summit in Gabala, Azerbaijan, proved a turning point. The theme for the summit was “Regional Peace and Security,” indicating the organization’s more open embrace of security issues. The leading section of the summit’s declaration focused on security issues and particularly put forward the objective of signing a “Treaty on Strategic Partnership, Eternal Friendship, and Brotherhood of Turkic States.” While not included in the formal communiqué of the summit, Azerbaijan offered to host the first military exercises under the banner of the OTS.
CONCLUSION: It is clear that, in the past few years, the OTS has been rapidly expanding its purview into the security area, defense industrial cooperation, and military coordination. It remains to be seen whether the OTS will transform into a formal alliance, as seems to be the intent of at least several of the member states. What is clear is that the OTS has turned into a vehicle for regional middle powers – specifically Kazakhstan, Uzbekistan, and Azerbaijan – to work to fill the security vacuum that has plagued the heart of Eurasia over the past three decades. That vacuum has been the result of the weakness of internal security arrangements in the region, as well as the prevalence of security arrangements dominated by external actors, such as Russia’s CSTO. While Türkiye is prominent among the OTS member states due to its military capabilities and the size of its economy, it is clear that the Turkic “middle powers” have been at least as forceful as Türkiye in driving the rise of Turkic cooperation.
Turkic cooperation is expanding and intensifying so rapidly that it can no longer be ignored. In many ways, the expansion of Turkic cooperation is directly in line with American and European policy objectives in Central Asia and the Caucasus. OTS activities are largely complementary to Western policies, while also filling voids that Western powers themselves have proven unwilling or unable to fill. For both the EU and the United States, the role of the OTS in maintaining a balanced international environment in Greater Central Asia has become significant enough that the factors limiting Western engagement with the OTS should not obscure the clear alignment of interests that is at play.
