Leaders and envoys met in Berlin on Monday, 15 December 2025, to pursue a negotiated end to Russia’s full-scale invasion of Ukraine, but no breakthrough was announced by evening. Ukrainian President Volodymyr Zelenskyy held multiple bilateral sessions — including with US special envoy Steve Witkoff — while European officials discussed security guarantees, possible territorial compromises and ways to mobilize frozen Russian assets. Fighting and infrastructure strikes continued on the ground during the talks, leaving hundreds of thousands without power and Russian forces advancing in parts of the east. The negotiating round in Berlin therefore combines high-level diplomacy with acute battlefield and economic pressures that shape what concessions, if any, Kyiv might accept.
Key takeaways
- More than a dozen European leaders assembled in Berlin on 15 December 2025 to press Ukraine-Russia ceasefire and settlement talks; closed-door sessions followed public meetings.
- A Kyiv International Institute of Sociology (KIIS) poll shows only 9% of Ukrainians expect the war to end by early 2026; 63% say they are prepared to endure the war as long as necessary.
- EU states have agreed to indefinitely freeze about €210 billion in Russian state assets in the bloc; a reparations loan proposal to channel those funds to Ukraine faces legal and political hurdles.
- Russian strikes left over 430,000 people without power in Odesa Oblast after weekend attacks, underlining the humanitarian stakes during negotiations.
- Kremlin spokesman Dmitry Peskov said President Putin is “open to peace” but rejects short-term ceasefires and insists Ukrainian neutrality (no NATO membership) is a core demand.
- German Foreign Minister Johann Wadephul and EU foreign chief Kaja Kallas framed the talks as unusually serious, while stressing that Ukraine must retain sufficient defense capacity.
Background
Diplomatic momentum toward negotiated terms has grown in late 2025 as battlefield gains and losses create urgency on all sides. Russia continues to press territorial demands, including Ukrainian withdrawal from parts of Donbas and formal neutrality that would bar NATO membership; Kyiv has repeatedly rejected concessions that would cede sovereign territory without ironclad security guarantees. Western capitals are divided over how far to push for territorial compromise versus firm guarantees and continued military support; that division became a central theme in Berlin as leaders weighed short-term relief against long-term security.
Economic leverage — chiefly the freezing of Russian state assets in Europe — has emerged as a parallel pathway to sustain Ukraine through reconstruction and defense costs. EU members approved an indefinite freeze on roughly €210 billion in Russian state assets, but converting those assets into a reparations-style loan requires new legal frameworks and broad political agreement. Meanwhile, domestic public opinion in Ukraine is a constraining factor: large majorities say elections should wait until a final peace arrangement and oppose territorial withdrawals without specific safeguards. Those attitudes shape Kyiv’s negotiating flexibility and its appetite for compromise.
Main event
On Monday, President Zelenskyy attended a packed schedule in Berlin: meetings with Germany’s head of state and lawmakers, an economic forum with Chancellor Friedrich Merz, then a group session with leaders including British Prime Minister Keir Starmer, French President Emmanuel Macron and EU institutional heads. Earlier talks in the German Chancellery had involved US envoy Steve Witkoff and, according to press accounts, Jared Kushner. German officials described Sunday evening’s discussions as “substantial,” though they emphasized substantive outcomes might not be clear until the end of the week.
The central negotiating topics included whether Ukraine would formally abandon a NATO accession bid in exchange for Western security guarantees tied to current frontlines; the scope of Ukraine’s future armed forces; and how frozen Russian funds could be transformed into long-term financial support. Ukrainian officials publicly rejected proposals that would require territorial withdrawals; their stated red line is preserving Kyiv’s defense capability and avoiding precedent-setting concessions that could invite renewed aggression.
Russia’s public posture, as outlined by Kremlin spokesman Dmitry Peskov, is to seek a definitive settlement rather than temporary pauses in fighting. Peskov reiterated that Moscow expects Ukraine to renounce NATO aspirations and cited territorial adjustments as central bargaining points. German and EU officials, while engaged in active diplomacy with both Kyiv and Washington, also signaled determination to maintain Ukraine’s defense capabilities in the event talks fail.
On the ground, fighting continued to influence political calculations: Russian forces captured the town of Pishchane in Dnipropetrovsk region, and weekend strikes on energy infrastructure left some 430,000 people without power in Odesa Oblast. These operational developments both boost the urgency of talks and limit the immediate room for concession, as Kyiv faces domestic pressure to avoid perceived capitulation while coping with civilian hardships.
Analysis & implications
The Berlin talks reflect a transition from tactical, short-term diplomacy to negotiations over permanent settlement architecture. If Ukraine were to formally forgo NATO membership in exchange for multilateral security guarantees anchored to current frontlines, the legal and operational design of those guarantees will determine whether Kyiv’s sovereignty and deterrence posture are preserved. Guarantees that are weak, temporary or unenforceable would likely be unacceptable to Ukrainian leaders and citizens, risking political blowback and future instability.
Using frozen Russian assets — approximately €210 billion — as the basis for a reparations loan is politically potent but legally complex. Several EU states, and notably Belgium where many assets are held, worry about litigation risks and banking exposures. Turning frozen accounts into long-term funding will require new EU-level instruments, majority votes in some forums, and careful legal insulation against counterclaims from Moscow. The long-run credibility of such a mechanism also depends on clear rules for oversight and repayment tied to verified reconstruction needs.
The KIIS poll — showing falling trust in the United States (from 41% to 21% year-on-year) and reduced confidence in NATO — signals a shift in Ukrainian public sentiment that could constrain Kyiv’s negotiating latitude. A population prepared to endure a prolonged war in pursuit of better peace terms strengthens the government’s hand against rushed deals, but also raises the political cost of prolonged fighting and infrastructure losses. Western capitals will weigh the domestic costs of continued aid against the strategic imperative to prevent further territorial erosion.
Finally, the talks risk producing a brittle compromise that satisfies neither battlefield realities nor public expectations. A settlement that pauses major combat without delivering durable deterrence or firm restitution could leave Europe vulnerable to future escalation. Conversely, insisting on maximalist conditions that ignore on-the-ground constraints could prolong the war indefinitely. Policymakers therefore balance deterrence, legal innovation on frozen assets, and the social resilience of the Ukrainian population in charting the next steps.
Comparison & data
| Metric | Result / share |
|---|---|
| KIIS: Approve peace plan freezing frontlines (with guarantees) | 72% |
| KIIS: Reject plan with Donbas withdrawal and limits on army | 75% |
| KIIS: Expect war to end by early 2026 | 9% |
| Trust in US (Dec 2024 → Dec 2025) | 41% → 21% |
| People without power in Odesa Oblast after weekend strikes | 430,000+ |
| Frozen Russian state assets in EU (agreed indefinite freeze) | ~€210 billion |
The table summarizes key public-opinion metrics and operational figures that frame the Berlin negotiations. The KIIS percentages reflect strong public resistance to territorial concessions without explicit security guarantees and a substantial willingness to sustain the war for a better peace. The drop in trust toward the United States suggests shifting perceptions of allied reliability and may influence Kyiv’s preference for multilateral, treaty-like guarantees rather than bilateral promises.
Reactions & quotes
German and EU officials framed the talks as unusually substantive while underlining the need to keep Ukraine’s defenses intact if diplomacy stalls. Officials also emphasized that any settlement must include practical security measures and not simply symbolic assurances.
“We will continue to do everything we can to ensure that Ukraine is in an optimal negotiating position,”
German Foreign Minister Johann Wadephul
Wadephul made this remark after meetings in Berlin, stressing that allies should both seek a settlement and preserve defensive capacity so Kyiv can respond if talks fail. He framed Western support as contingent on credible Ukrainian deterrence and operational readiness.
“If it gets Donbas, then the fortress is down,”
EU foreign policy chief Kaja Kallas
Kallas warned reporters that accepting Donbas as an endpoint for Russia would presage further advances and destabilization in Europe, urging tangible guarantees such as deployed capabilities rather than only diplomatic commitments.
“[Putin] is open to peace, to serious peace … He is absolutely not open to creating artificial respites,”
Kremlin spokesman Dmitry Peskov (citing TASS)
Peskov spoke to state media outlining Russian expectations, emphasizing that Moscow rejects temporary ceasefires and links any settlement to Ukrainian neutrality and territorial concessions in the east.
Unconfirmed
- Allegations that US envoys coordinated positions with Moscow ahead of Berlin meetings have been reported but lack direct public evidence from either Washington or the Kremlin and remain unverified.
- Reports that Russia has already decided to accept Ukraine dropping NATO aspirations in exchange for specific territorial gains are speculative and not confirmed by Moscow’s formal negotiating team.
- Some media accounts suggest private understandings on troop-level limits for Ukraine; these reports are not yet corroborated by official, published agreements.
Bottom line
Berlin’s talks mark a consequential diplomatic moment: leaders are discussing trade-offs that could reshape Ukraine’s security architecture, Europe’s legal handling of frozen Russian assets, and the balance between immediate relief and long-term deterrence. Public opinion in Ukraine — broadly hostile to territorial concessions without guarantees — constrains Kyiv’s negotiating flexibility and raises the political cost of rapid settlements.
Absent a clear enforcement mechanism for any security guarantees and a legally robust path to repurpose frozen assets, negotiations risk producing fragile accords that neither end hostilities nor prevent future aggression. The coming week of closed-door diplomacy will be decisive: if Western partners coalesce around enforceable guarantees and a practical reparations instrument, a durable settlement becomes more plausible; if divisions persist, the war is likely to continue with periodic diplomatic spurts and substantial human costs.
