Trilateral negotiations aimed at ending Russia’s full-scale invasion of Ukraine resumed in Abu Dhabi on Monday, with American officials signalling that both Moscow and Kyiv have shown a degree of behind-the-scenes pliability on the fate of Ukraine’s eastern regions. The talks, led by US peace envoy Steve Witkoff and senior adviser Jared Kushner, mark the first direct engagement since February’s Geneva round collapsed without progress. While public positions remain hardened — Russia demands Ukraine cede the portions of Donetsk it still controls; Kyiv insists on freezing the current contact line — a US official briefing reporters on the eve of the discussions said the two sides had demonstrated “a little bit of flexibility, privately.” The official cautioned, however, that any territorial settlement remains hostage to a broader agreement on postwar security architecture.
The Donetsk Deadlock and the Security Architecture Puzzle
The impasse over Donetsk has long been the most tangible obstacle to a ceasefire. Russian forces occupy the vast majority of the region, but Ukrainian troops retain control over a string of fortified positions — what military analysts call a “fortress belt” — that Kyiv views as essential to its defensible borders. Moscow’s public demand is unambiguous: relinquish those remaining footholds. Ukraine’s counter-proposal, a freeze along the current line of contact, would effectively legitimise Russian gains while preserving a defensive buffer.
The American official acknowledged the two issues are inseparable. “They will not solve the Donetsk issue and the territorial issue until they know what the security architecture is going to be after the war,” the official said. “And keep in mind, we’re not going to be able to finalise one without the other.”
For Kyiv, that architecture means binding guarantees — Article 5-style commitments or bilateral security pacts — that allies will respond militarily to any future aggression. For the Kremlin, the phrase has long signified a rollback of NATO’s eastern flank, a demand that would fundamentally reshape the European security order established since the Cold War. The framework under discussion in Abu Dhabi reportedly includes crisis communication hotlines, reciprocal de-escalation measures and the potential reactivation of the NATO-Russia Council, dormant since 2022.
Europe Demands a Seat at the Table
European capitals have watched the bilateral US-Russia engagement with mounting alarm. French Foreign Minister Jean-Noël Barrot was adamant ahead of the talks that France, the United Kingdom and Germany “will indeed be in the meeting room.” European Commission President Ursula von der Leyen echoed the sentiment on Monday, urging that NATO allies and EU members be included in any “meaningful discussions about Europe’s security architecture.”
Their anxiety is not abstract. Since Donald Trump returned to the White House, his administration has pursued a diplomatic track that often sidelined European partners, even as the continent bears the brunt of refugee flows, energy disruption and the direct military threat. The US official confirmed Washington would propose shifting to a multilateral format that brings Europeans into the process. “Hopefully we’ll get the Russians on board,” the official said, adding with notable candour that “the Russians have a bad taste in their mouth with the Europeans.”
Delegations Signal Seriousness, but Battlefield Reality Bites
The composition of the delegations suggests both Moscow and Kyiv are treating the talks as more than theatre. Russia’s team includes Kremlin aide Vladimir Medinsky, deputy foreign ministers Sergei Ryabkov and Mikhail Galuzin, GRU chief Igor Kostyukov and General Yury Zhigarlovsky — a blend of diplomatic, intelligence and military heft. Ukraine has dispatched Foreign Intelligence Service head Rustem Umerov, presidential chief of staff Kyrylo Budanov and MP Davyd Arakhamiya, veterans of previous negotiating rounds.
Yet the violence has not paused. Russian bombardments continue to pound Ukrainian cities and energy infrastructure, a campaign Kyiv interprets as leverage-building ahead of any settlement. On Monday, Kushner struck a cautious tone on X, writing that the Abu Dhabi talks could at most “build momentum toward the next phase of negotiations.” He described the conflict as “extraordinarily difficult and complicated,” adding that the US was “approaching these discussions with determination and realism.”
That realism is tested by Trump’s own recent moves. His meeting last week with Kremlin envoy Kirill Dmitriev in Washington produced talk of a “big, beautiful agreement” that “might involve all of Europe.” But the president’s concurrent deal to purchase Russian diesel — and his longstanding scepticism of NATO — have deepened suspicions in Kyiv and Brussels that Washington may prioritise a quick deal over a just one.
Ukrainian MP Oleksandr Merezhko, who chairs the parliamentary foreign affairs committee, did not mince words. “Trump wants a quick deal at the expense of Ukraine,” he told the BBC. “While Putin has a war machine up and running, he has no incentives to negotiate.” Merezhko argued that only intensified sanctions and deep strikes inside Russia could compel genuine engagement from the Kremlin.
Why it Matters
The Abu Dhabi talks represent more than another diplomatic off-ramp in a grinding war; they are a stress test for the transatlantic alliance and a preview of how great-power competition will be managed in an era of shifting alignments. If the US and Russia forge a European security framework without Europeans, the precedent will resonate far beyond the Donbas — from the Baltic states to the Taiwan Strait, where allies are already questioning whether Washington’s security guarantees are conditional on domestic political winds. A deal that freezes territory without securing sovereignty risks legitimising conquest by force, eroding the post-1945 order that has underpinned stability in both Europe and the Indo-Pacific. The flexibility reported in private rooms may yet prove illusory, but the structural questions it surfaces — who guarantees whom, and at what cost — will outlast this conflict.
