In the aftermath of the explosive-drone incident at Leipzig airport, German Foreign Minister Wadephul on 1 September announced a package of measures against Russia, including the closure of Germany’s last remaining Russian consulate-general in Bonn and the termination of the bilateral agreement governing the activity of Russian and German cultural centres – chief among them the “Russian House” in Berlin.

Investigative reporting on the House had built momentum for this outcome: Correctiv, publishing on the same day, laid out allegations that the House served as a hub for propaganda, sanctions-evasion, and, per a July 2026 French expulsion order against former RT France chief, cover for Russian intelligence activity. Against that backdrop, the announcement was widely read – by Ukraine-solidarity campaigners, by the German media and by politicians in the run-up to Berlin’s 20 September Abgeordnetenhaus election – as the long-awaited closure of Putin’s espionage exclave in the German capital. Jubilations ensued as the framing that took hold was reinforced by headlines flatly stating the House “will be closed”, treating the announcement as a legal outcome.

Moving forward on the path of definite closure will, however, involve cutting a number of legal Gordian knots: the entanglement of two treaties running on separate legal tracks and a dispute-settlement architecture that, on closer inspection, has no judge willing to cut the knot. While Germany says it will close the House, Russia may play legal cat and mouse.

Two Treaties

Two legal analyses published within days of the 1 September 2026 ministerial announcement (here and here) explained that the Russian House’s legal architecture rests on two separate treaties. The first is the 2011 agreement (in force since 2012, UNTS No. 50173) on the activity of cultural and information centres, which governs the House’s operations (and those of the Goethe-Institut in Moscow). This is the instrument Wadephul’s announcement undoes using its ordinary termination provision: it runs in five-year periods and can be terminated by diplomatic notice at least six months before the end of each period. Russia’s symmetrical response on 3 September – if followed up by formal notice – would cause the 2011 agreement to expire on 6 June 2027.

The second, entirely separate 2013 agreement (UNTS No. 51454) governs the underlying property relations of the Russian House (and, reciprocally, the Goethe-Institut in Moscow). In Berlin, Germany owns the land; the Russian Federation owns the building complex and holds a gratuitous right to use the land. The arrangement reflects the separate ownership of land and building from the GDR-USSR regimes, yet it is a sui generis intergovernmental settlement rather than an Erbbaurecht (hereditary building right) under German private law. It replaced the 1982 construction and land use agreement as well as the 1984 protocol transferring the building to Soviet ownership. Like a classic German ground lease, the 2013 property agreement (Art. 5) runs for 99 years followed by automatic extension unless notice is given at least twelve months before expiry (mid-2112).

Terminating the 2011 agreement therefore does not, by itself, extinguish the second under which the seven-story brutalist building remains the property of the Russian Federation – a point emphasised by Patrick Heinemann in his analysis. When the German MFA spokesperson announced that “We’re looking into other options for termination. But that would make things a bit more complicated”, he engaged in euphemism.

A Bargain Never Kept

How could Germany terminate the 2013 agreement then? It could in principle be dissolved or suspended ahead of schedule under Art. 60(1) of the 1969 Vienna Convention on the Law of Treaties (VCLT) for material breach, keeping in mind that the operative property provisions were structured as a reciprocal bargain: Germany granted the Russian side gratuitous use of the Berlin site (0.65 ha), while Russia undertook to make the Moscow venue (0.68 ha) available to Germany on essentially the same terms. The near-mirror sizing and reciprocal drafting suggest the treaty’s object and purpose was this parallel exchange – not cultural cooperation in the abstract (the 2011 agreement’s domain), but the specific property quid pro quo. That synallagma, however, did not materialise as the Goethe-Institut never relocated to its promised Moscow address. Sources point to documented delays in the conclusion of the lease agreement, but Germany never went as far as to claim material breach. A breach argument, however, runs into the problem of timing. Germany’s 13 years of continued performance, despite Russia’s failure to deliver its side of the bargain, could amount to acquiescence under Art. 45(b) VCLT, barring Germany from now invoking that failure as a ground for termination.

Art. 62 VCLT (termination due to a fundamental change of circumstances) offers Germany a second possible ground but sets a narrow four-step test: the change must be fundamental, unforeseen, have been an essential basis of the parties’ consent, and radically transform the obligations still to be performed. The ICJ has applied these conditions strictly. In Gabčíkovo-Nagymaros, Hungary invoked the collapse of the Soviet bloc and the political transformation of Central Europe as a fundamental change of circumstances. The Court rejected the argument: even those profound geopolitical changes did not satisfy Art. 62.

Germany’s argument here would have to run through the preamble’s language on the parties’ “mutual desire to continue to expand the wide-ranging cooperation in the fields of culture and science” – asserting that Russia’s turn to hybrid warfare against Germany has fundamentally and unforeseeably transformed the basis on which that cooperation was ever agreed. The position rests on characterising a broad shift in the bilateral relationship, not on pointing to a specific, provable failure to perform. Where Art. 60 may give Germany a concrete grievance – the failure to provide the Moscow site –, Art. 62 offers a more abstract one that builds on inference from preambular language and the general deterioration of relations.

Missing Forum

Suppose Germany’s Art. 60 or 62 case is sound. It still would have to survive the Vienna Convention’s dispute-resolution machinery. Under Art. 65 VCLT, the state invoking a ground for termination must formally notify the other party, which then has at least three months to object. If Russia objects, as is realistic here, both states must seek a solution through negotiation, mediation, conciliation, arbitration, or judicial settlement – none of which either side can be compelled to accept. If this produces nothing within twelve months, Art. 66(b) would normally let either party unilaterally convene a conciliation commission – the one mechanism the Convention supplies for a dispute of this kind. But this almost certainly does not apply between Germany and Russia: the Soviet Union entered a reservation rejecting Art. 66 outright, and Russia continues to be treated as its successor for treaty purposes. The result is that no compulsory mechanism exists to resolve a contested termination – the dispute remains political and diplomatic by default, however sound Germany’s underlying legal argument might be. Strip away the procedure and the result is: no judge, no forum, no closure.

All this leaves us with a sense of desperation, as we have been oversold on the narrative of the Russian House “closing”. While the 2011 agreement will lapse due to non-renewal, the Russian Federation will, realistically, continue to exercise property rights over the Friedrichstraße-compound.

To Be or Not to Be Immune?

With the lapse of the 2011 agreement on 6 June 2027, Russia loses the treaty basis for operating the House as the bilateral cultural centre. Yet the obligation to stop operating belongs to a different legal domain than the question of whether Russia’s property will continue to benefit from immunity against enforcement. The former is concerned with whether Russia is entitled to keep operating the House; the latter inquires whether a German court, faced with a request of a creditor to seize or execute against it, must treat it as untouchable. The two do not automatically walk in sync. Consider a realistic scenario: Russia ignores the obligation and keeps the House running in open breach of what international law now requires of it. What happens if someone tries to enforce against the property?

The immunity question is governed by a separate test and it has already been litigated over this very building. In 2009, a creditor holding a Stockholm arbitral award against Russia sought to seize rental income the House earned by subletting part of its premises to a shop tenant. In that case, the BGH set a low evidentiary bar for clearing the immunity test: a foreign state need not conclusively prove that an asset serves a sovereign purpose, only render it plausible (Glaubhaftmachung, §39) – in practice, little more than its sworn assertion. Applying that standard to the scenario above, a court would likely still classify an unchanged House as a functioning cultural institution and grant immunity – regardless of the treaty’s demise and regardless of Russia’s ongoing breach. Withdrawn German consent, according to precedent, does not itself feed into that classification.

One could imagine a novel argument along these lines that unauthorised continuation over the host state’s explicit objection should now count against the activity’s sovereign character. But this isn’t an avenue open to the German state: immunity from execution is litigated in civil proceedings brought by private parties. It would take a private creditor or claimant – someone holding an enforceable judgment or arbitral award against Russia, as in the 2009 case – to bring an enforcement action and put this question to a court; no such proceeding has yet done so. Absent a claimant bringing such a case and a court accepting the argument that the House’s continued use is no longer sovereign, there is no route to execution against it. Ending the treaty is a far weaker remedy than the closure framing suggests.

What Closure Would Require

Announcing political sanctions alone is, as we have discussed, insufficient to overcome international legal obstacles associated with the closure and seizure of foreign diplomatic and cultural institutions. If the German government were prepared to pursue closure through available legal avenues rather than relying on the symbolic weight of the announcement, two measures stand out. First, Germany should formally invoke the Art. 65 VCLT procedure against the 2013 property agreement itself, on Art. 60 or Art. 62 grounds. This establishes a record and starts the treaty’s own dispute-resolution timeline; on its own, it does not, however, resolve anything, given the forum gap described above.

Most immediately available, Germany could rigorously enforce the sanctions already in place against the House. Rossotrudnichestvo – a Foreign Ministry agency which runs a network of around 80 Russian cultural houses worldwide – has been EU-sanctions-listed since 2022 and the Munich Administrative Court held in 2025 (still under appeal) that the asset-provision ban under Art. 2(2) of Regulation (EU) No. 269/2014 already prohibits supplying the House with utilities beyond what its bare survival requires. The exception does not extend to operating the House as a cultural centre. Because this targets German suppliers rather than Russian state property itself, it sidesteps the treaty-termination problem: no international forum is needed, since Germany would simply be regulating its own companies. What has been missing is not a legal instrument, but its systematic enforcement against the House and the German companies and service providers that kept it operating.

Lessons from Glinkastraße

The closure of the City Hostel, less than half a kilometre away from the Russian House, offers a useful lesson. Commercially operating on the grounds of North Korea’s embassy, it generated revenue for Pyongyang contrary to UN Security Council Resolution 2321 (2016), which prohibits the use of real property in Member States’ territories for purposes other than diplomatic or consular activities. Yet domestic enforcement still took some three years after the Federal Foreign Office determined that the hostel had to close. Berlin did not need to resolve the underlying question of title. It achieved closure by enforcing applicable sanctions through domestic law. The Russian House is legally more complicated, particularly because of the 2013 property agreement and the immunity it affords for sovereign use. Nor does closing the cultural centre necessarily eliminate the security threat. “Cultural activities” may cease, but the building remains Russian-owned and its numerous offices and residential units would not thereby disappear. If the GRU uses the building for clandestine operations, terminating the cultural-centre agreement does not prevent its continued use for those purposes. The broader lesson is relevant: where treaty termination does not produce closure, domestic enforcement may.

The government’s 1 September announcement sparked premature jubilation amongst circles showing solidarity with Ukraine who have campaigned for closing down the House since 2022. But it achieves less than the headlines suggest: it terminates one operational treaty mechanism, not the property regime. The Russian House may lose its treaty basis for operating as a cultural institution, but the Russian Federation’s property title does not disappear merely because the 2011 agreement ends. Germany should therefore pursue the difficult international legal route against the 2013 property agreement, use domestic sanctions and regulatory powers to constrain any continued operation. The political announcement is not itself the legal act of closure.
