Russia's Neighbourhood: Between the Barrier and the Reactor
On the same day Latvia began hardening its border with Russia, Moscow was deepening its strategic embrace of Kazakhstan — a same-day contrast that lays bare the divergent directions post-Soviet space has taken since 2022.
Latvia's military began installing the first of what officials call "dragon's teeth" — the saw-toothed concreteanti-tank obstacles that have become a visible feature of NATO's eastern flank — along the Russian border on 28 May 2026, according to LSM, Latvia's public broadcaster. The Latvian Armed Forces confirmed the deployment as a deliberate hardening of the frontier, part of ongoing border-defence acceleration that has intensified since Russia's 2022 full-scale invasion of Ukraine.
That same morning in Moscow, Russian President Vladimir Putin sat across from Kazakh President Kassym-Jomart Tokayev for a meeting that produced two substantive outputs. Moscow and Astana signed an agreement paving the way for a Russian-built nuclear power plant on Kazakh territory. Putin and Tokayev also affixed their signatures to a joint statement outlining what Kazakh state media described as seven foundational principles of friendship between their peoples.
The coincidence of timing is the story. Across more than 6,000 kilometres of post-Soviet frontier, two of Russia's neighbours responded to the same signal — the continued presence of a revisionist Moscow — in directly opposite directions.
The Fortification
The dragon's teeth in Latvia sit at the end of a supply line that did not exist in meaningful form before 2022. NATO's Enhanced Forward Presence, which placed multinational battlegroups in the Baltic states in 2017, was a start. But the ground has moved. Latvia in 2025/26 has been accelerating infrastructure —固定的防御阵地, hardened command facilities, stockpiles pre-positioned along the eastern border — that senior officers in Riga describe as transitioning from a deterrence posture to active defence preparation.
The barriers themselves are low-tech and non-negotiable. Dragon's teeth — pyramidalconcrete rows — do not stop an army by themselves. They slow it, channel it, buy time for defenders to respond. In Latvia's framing, that is precisely the point. NATO planners have consistently emphasised that the alliance's Baltic challenge is not holding territory but holding time: bridging the gap between first contact and reinforcements flowing from the alliance's core to the flank.
Latvia's border with Russia runs approximately 214 kilometres. Not all of it is forested or defensible terrain. The barriers are being placed at priority points, LSM reported — likely choke points, road intersections, and crossing approaches identified in Riga's own threat assessments. LSM is the public broadcaster; its reporting carries the authoritative weight of a taxpayer-funded outlet that serves both Latvian and Russian-speaking audiences.
The Diplomatic Arc
The nuclear agreement with Kazakhstan is a harder signal to read than the concrete barriers. Kazakhstan is not Belarus. It has not subordinated its foreign policy to Moscow. Tokayev's government has maintained Astana's formal neutrality-in-practice throughout the Ukraine conflict: it has not recognised Russian annexation of Ukrainian territory, has hosted peace-formula discussions, and has continued to engage with Western partners without openly breaking with Russia.
That makes the nuclear deal more significant, not less. It does not read as pressure or coercion. It reads as a consensual deepening — a country with alternatives choosing to go further with Moscow. Kazakhstan has uranium reserves that rank among the world's largest. It had been exploring nuclear power independently before this agreement. The Russian-built plant, if it proceeds on the timeline implied by the 28 May signing, locks in Russian technology, Russian contractors, and a Russian footprint in Kazakhstan's energy architecture for a generation.
The "seven foundations of friendship" language is deliberate framing. It is bureaucratic shorthand for an incremental legal architecture — defence consultation clauses, economic coordination commitments, cultural exchange protocols — that normalises a relationship far deeper than the two countries' official alliance rhetoric would suggest. Kazakhstan's constitution does not permit foreign military basing without parliamentary approval, a constraint Tokayev has invoked more than once. But defence consultation does not require bases. It requires forums. Forums breed habits. Habits, over time, become dependencies.
Reading the Gap
Western analysis has sometimes struggled with the Kazakhstan-Russia dynamic because it resists the binary into which Ukraine has forced much thinking: aligned or occupied, sovereign or subservient. Kazakhstan is sovereign and navigating. It is also, by geography, inevitably within Russia's gravitational field in ways the Baltic states are not.
Latvia shares a border with Russia that runs through an open plain, but it sits behind a much thicker institutional membrane: NATO membership, EU association, and decades of integration into Western political and economic structures. Kazakhstan shares a 7,500-kilometre border with Russia — the longest continuous frontier on earth — and has no such membrane. Its challenge is not choosing between blocs but managing bilateral exposure to a neighbour whose resources, population, and military capacity dwarf its own.
The nuclear deal is Kazakhstan's hedge in energy security as much as it is a concession to Moscow. Astana has been public about its ambitions for a domestic nuclear programme. Rosatom is the vendor with the most competitive offer and the shortest timeline. That does not make it a political gift to Putin — it makes it a pragmatic one.
What Comes Next
The dragon's teeth in Latvia are not going anywhere. Latvia's government has been consistent: the fortifications are permanent infrastructure, not a temporary deployment. That signals a long-term institutionalisation of the threat perception — the assumption that whatever the ceasefire terms in Ukraine, the strategic posture vis-à-vis Russia does not revert to pre-2022 baselines.
For Kazakhstan, the question is subtler. Tokayev was re-elected in 2024 in a poll that Western observers described as orderly but constrained. His government maintains an active engagement with Western capitals — Kazakh delegations continue to visit Brussels, Washington, and Beijing with investment pitches. The nuclear agreement does not close that diplomacy. But it does narrow it. Every major infrastructure project given to Rosatom is a project not given to South Korea's KEPCO, France's EDF, or China's CNNC. The menu of options, over time, thins.
On one morning in May 2026, the map of post-Soviet space showed a NATO member building a wall and a non-aligned sovereign signing up for a reactor. Both are rational responses to the same underlying reality. That they are responses in opposite directions is not a paradox. It is the honest geography of a neighbourhood that has not finished deciding what it is.
