Strategic Border Closure Marks New Phase in Nordic Security Doctrine

In a decisive move emblematic of Finland’s evolving national security posture in response to geopolitical turbulence on its eastern frontier, the Finnish government has announced its intention to maintain the closure of its land border with the Russian Federation until further notice. This policy decision, formally confirmed on April 16, 2025, shows Helsinki’s enduring apprehension over what it perceives as a coordinated campaign by Moscow to manipulate migratory flows as a strategic lever of hybrid warfare—a form of coercion wherein non-military means are weaponized to achieve political ends.

The border, stretching over 1,300 kilometers and historically one of the principal gateways between the European Union and Russia, was originally sealed in the final months of 2023. The closure came amidst a sudden and conspicuous spike in the arrival of third-country nationals—particularly asylum seekers from nations such as Syria and Somalia—at Finnish border checkpoints. Finnish authorities quickly characterized this surge not as a random migratory fluctuation but as the deliberate orchestration of cross-border movements by Russian state actors, executed in retaliation for Finland’s accession to the North Atlantic Treaty Organization (NATO), a development that altered the regional security calculus and drew the ire of the Kremlin. While Russia has officially denied any involvement in facilitating these migratory flows, Finnish intelligence and governmental assessments have remained steadfast in their attribution of responsibility.

In a public statement, the Finnish government emphasized that “the risk that instrumentalised migration will resume and expand as seen previously remains likely.” This phraseology reflects a persistent concern within Finnish security circles that any premature reopening of the border could once again render the country vulnerable to externally manufactured humanitarian pressure. This strategy, often referred to as “migratory weaponisation,” entails the deliberate facilitation or coercion of vulnerable populations to cross into an adversarial state’s territory, thereby overwhelming administrative and logistical capacities, sowing domestic discord, and destabilizing public confidence in governmental institutions.

To guard against such contingencies, Finland has taken the additional and highly unorthodox step of invoking a state of emergency provision within its legal framework. Under this exceptional legislative measure, Finnish authorities are empowered to summarily reject asylum applications submitted by individuals entering the country via the closed eastern border. Furthermore, the policy authorizes the physical return of such individuals to the Russian side, notwithstanding prevailing international norms governing the rights of asylum seekers and the principle of non-refoulement. This approach, while controversial among humanitarian and legal advocates, has been defended by the Finnish government as an indispensable tool for preserving national sovereignty and ensuring the integrity of border control mechanisms in the face of what it views as an unconventional and deliberate attack on its internal stability.

Though Finnish officials have stated that the current closure will be subject to regular reassessment, they have also made it clear that the criteria for reopening the border are stringent. Specifically, any reconsideration of the current policy will be contingent upon a determination that such an action no longer constitutes “a serious threat to national security or public order.” This formulation reveals the deep-seated anxiety within Finland’s strategic establishment regarding the durability of the threat posed by its eastern neighbor, particularly in light of the broader deterioration of European-Russian relations following the invasion of Ukraine and Finland’s subsequent NATO accession.

As Finland consolidates its new geopolitical identity within the Western security bloc, its approach to border management with Russia serves as a potent symbol of its shifting priorities—from a traditionally neutral stance to one characterized by heightened vigilance and alignment with transatlantic security norms. The continuation of the border closure not only reflects Finland’s defensive recalibration but also sends a signal to its NATO allies that it is prepared to exercise firm and preemptive measures in the face of asymmetric threats emanating from the Russian Federation.
