Transnistria: The Thawing of a Frozen Conflict?

Introduction

Last week, Sergei Shoigu, secretary of the Russian Security Council, issued a warning regarding the safety of Russian citizens living in Transnistria. Speaking to Russian media, Shoigu stated "It must not be ⁠forgotten that more than 220,000 Russian citizens live in Transdniestria. Their interests and safety are now ​under threat due to the ill-considered and irresponsible actions of Kyiv and Chisinau." Furthermore, he pointed out that Russia would defend its citizens in the de-facto state by any means necessary, even with potential military action.

These chilling remarks have drawn attention to one of Europe’s longest-running unresolved conflicts. While they may turn out to be empty threats, these statements reflect a deeper reality: ‘frozen’ conflicts are not stable historical remnants; rather, they are geopolitical tools that can be wielded to the advantage of great powers, particularly Russia, when the need arises. As the war in Ukraine continues, Transnistria is increasingly becoming useful to Russia due to its bordering of Ukraine.

History of Transnistria

The separatist region of Transnistria emerged in 1990 during the collapse of the Soviet Union. As Moldova moved toward independence from the USSR, tensions grew between the central Moldovan government and the largely Russian-speaking population in the east of the country, along a strip of land between the Ukrainian border and the Dniester River. These tensions resulted in a short but deadly conflict in 1992, ending with Transnistria breaking away from Moldova. Since then, it has functioned as a de facto state, a political entity that lacks formal international recognition as a country. They “control defined territory, run functioning governments, and provide public services to their populations, yet they exist outside the formal system of sovereign states”.

Transnistria’s de facto state status is heavily sustained by Russian political, economic, and military backing, with approximately 1,200 Russian troops stationed in the region. This arrangement has essentially left the conflict unresolved, or ‘frozen’, allowing Russia to maintain influence in the region without the disadvantages that come with direct confrontation, i.e. maintaining plausible deniability. 

Recent Developments: Russia, Protection Narratives, and Ukraine

The latest statements from the Russian Security Council are best understood within a geostrategic sense. Russia’s emphasis on protecting its citizens outside of its borders in post-Soviet states has become a prominent feature of Russian foreign policy, and it is certainly not new. In Putin’s 2022 speech announcing the invasion of Ukraine, he stated “the purpose of this operation is to protect people who, for eight years now, have been facing humiliation and genocide perpetrated by the Kyiv regime”, a statement widely rejected by the international community. In this sense, claims of protecting Russian citizens abroad have served as justification for much of Russian foreign interventions. As a large proportion of the Transnistrian population holds Russian passports, this narrative is easily transferable, and it further reinforces the idea that regions with a high Russian population remain within Russia’s sphere of influence, regardless of formal status.

Moldova’s hopes for future EU accession means that Transnistria is less of a dormant historical issue. Coupled with the Russian invasion of Ukraine, the de facto state has taken on renewed strategic significance for Russia. Transnistria’s geographic location bordering Ukraine places it adjacent to an active conflict zone, intensifying its importance in the broader regional security environment. While it is unlikely that escalation will occur in the near future, the recent comments made by the Russian Security Council, and its proximity to Ukraine’s western flank, highlight a potential point of strategic influence for Russia.

Frozen Conflicts as Strategic Instruments

Transnistria is not the only ‘frozen conflict’ in the post-Soviet space to repeatedly evolve depending on shifting geopolitical conditions, often acting as an instrument of Russian influence. Abkhazia and South Ossetia, Russian-aligned de facto states situated between Georgia and Russia, had relatively contained disputes until they were reactivated during the 2008 Russo-Georgian War. This highlights how such conflicts can be escalated if strategically advantageous for Russia. A more recent example can be seen in the limited conflict in eastern Donbas, which ultimately expanded into a wider war in Ukraine, laying the foundation for broader confrontation between Russia and the West. Thus, these cases suggest that ‘frozen’ conflicts are neither stable nor final. Rather, they are flexible tools to be employed subject to strategic context. Hence, ‘frozen’ should be interpreted as a temporary phase rather than a set-in-stone condition. Furthermore, such unresolved conflicts also complicate the Euro-Atlantic ambitions of states such as Moldova and Georgia, acting as obstacles to NATO and EU integration and, in doing so, helping to maintain Russian influence in the region.  

Conclusion

Transnistria will not become a major battlefield anytime soon; however, that is not to say it is insignificant. The case of Transnistria reflects a broader pattern in contemporary geopolitics: unresolved ‘frozen’ conflicts are not historical antiques with finalised outcomes, rather, they are preserved sources of leverage that can be reactivated when needed, particularly when tensions between Russia and the West reach a boiling point, as seen in 2008 and 2014. 

In this sense, Transnistria is not an anomaly, but instead part of a wider system of managed, strategic instability across the post-Soviet space. It may be a burden for Moldova, as Abkhazia and South Ossetia are for Georgia, but for Russia, it is inherently valuable, precisely because of its unresolved status. In an increasingly turbulent geopolitical environment, such unresolved conflicts and de facto states are not Russian liabilities, but assets.
