Trilateral loses venue, keeps deadlock

The third US-Russia-Ukraine trilateral cannot meet in Abu Dhabi and may relocate to Istanbul, but the harder problem — Russia's demand that Ukraine cede four oblasts before talks continue — has not moved.

ConflictDeveloping

Key takeaway

Istanbul hosted a near-deal in 2022 that collapsed; its symbolic freight complicates its neutrality as a venue.

The third round of US-Russia-Ukraine trilateral negotiations, scheduled for 5–6 March, cannot proceed in Abu Dhabi because of the wider Middle East conflict. President Zelenskyy confirmed on 2 March that the talks are not cancelled — only the venue is unresolved ¹. Bloomberg sources identified Istanbul as the front-runner replacement ², and Turkey's Anadolu Agency separately reported that Russia confirmed the city ³. No final announcement had been made as of 5 March.

The venue disruption matters less than what awaits any table they sit around. Russia's precondition — that Ukraine formally cede Donetsk, Luhansk, Zaporizhzhia, and Kherson before talks continue — remains on the table. Moscow has issued structurally similar ultimatums before every round since 2022 and attended regardless, a pattern that suggests the demand functions as a negotiating anchor rather than a genuine walk-away trigger. The second Abu Dhabi round in February achieved technical progress on ceasefire monitoring mechanics but deadlocked on territory, security guarantees, and the composition of any monitoring force . None of those positions have shifted.

Three constraints define the negotiating space regardless of city. Trump told Zelenskyy on 25 February he wanted the war ended "in a month" ; Russia's stated position remains "no deadlines." The trilateral format excludes all 27 EU member states despite Europe having funded more of Ukraine's war effort than the United States — a gap Germany's chancellor addressed directly in Washington on 3 March. And the substantive deadlock is circular: Ukraine will not concede territory in advance, Russia will not negotiate without that concession, and Washington has not indicated which side's position it considers more negotiable.

Deep Analysis

In plain English

Peace talks between the US, Russia, and Ukraine were due in Abu Dhabi but had to move because of unrelated Middle East tensions. Istanbul is the replacement. Turkey has maintained relationships with both sides throughout the war — selling weapons to Ukraine while buying gas from Russia — which makes it acceptable to both parties as a host. The venue matters less than the substance. Russia still insists Ukraine formally hand over four regions before talks can proceed. Crucially, Ukraine's constitution prohibits surrendering territory without a national referendum — a legal barrier that no Ukrainian president can waive by executive decision, regardless of US pressure. Russia has made similar demands before every previous round and attended anyway, which suggests the precondition serves a domestic audience rather than being a genuine deal-breaker.

Deep Analysis

Synthesis

Ukraine's constitution (Article 157) bars altering state territory without a national referendum — a legal constraint Zelensky cannot waive by executive decision regardless of pressure from Washington. Russia's four-oblast precondition is therefore structurally incompatible with Ukrainian constitutional law, not merely with Ukrainian political will. This suggests the precondition functions as a procedural legitimisation device for Russian domestic audiences rather than a genuine negotiating position — which would explain why Russia consistently attends talks regardless of unmet demands.

What could happen next?

Risk
Venue uncertainty delaying the 5–6 March meeting risks dissipating technical momentum from the second round's progress on ceasefire monitoring.

Consequence
A framework agreed before European observer status is secured gives Merz's implementation veto immediate practical teeth, creating post-agreement deadlock between the US-brokered text and European non-endorsement.

A deal concluded in trilateral format without European participation sets a structural template for US-Russia bilateralism that excludes EU institutional role in European security architecture.

Ukraine×4

LeftRight

Primary parallel: The March–April 2022 Istanbul talks produced a documented draft framework — Ukraine offered neutrality and force-size limits; Russia offered withdrawal from Kyiv Oblast. The draft collapsed; both sides subsequently blamed the other, with Russian officials and some Ukrainian negotiators later suggesting Western pressure also contributed. Istanbul therefore carries both a near-breakthrough precedent and a failed-deal legacy.

Counter-parallel: The 1994 Budapest Memorandum was negotiated without European institutional participation and produced legally ambiguous security assurances that proved unenforceable when tested in 2014. US-brokered bilateral security frameworks that exclude multilateral architecture have a documented failure mode directly relevant to the current format.

Why it’s relevant now

The 2022 draft's collapse under contested circumstances means Ukrainian hardliners and Russian nationalists will both treat any Istanbul-branded framework as politically contaminated before substantive talks begin. Venue symbolism is not neutral.

Consensus view: Carnegie Endowment analysts tracking the negotiating record note that Russia's pre-talk demands function primarily as domestic signalling — attendance despite unmet preconditions is the operationally meaningful indicator of actual negotiating intent.

Counter-view: The International Crisis Group's Istanbul office has argued that Turkey's dual-track relationships with Moscow and Kyiv give Ankara genuine mediation leverage, but that sequentially hosting multiple rounds risks eroding Turkish neutrality in both capitals' perceptions — reducing Ankara's future utility as a mediator.

Key tension: Whether Erdogan's political interest in a high-profile diplomatic outcome creates pressure to declare progress prematurely, locking in a framework before verification mechanisms are agreed.

This Event

Trilateral loses venue, keeps deadlock

The venue disruption is trivial; the structural deadlock is not. Russia's four-oblast precondition, Europe's exclusion from a process it must fund and enforce, and the gap between Trump's one-month timeline and Moscow's refusal of deadlines together define a format that may lack the participants and the flexibility to produce a durable agreement.

Different Perspectives

IAEA

Director General Rafael Grossi appeared in person at the UNSC on 19 May and warned that a direct hit on an operating reactor 'could result in very high release of radioactivity'. The session produced a condemnation record but no resolution, and the Barakah perimeter was already struck on 17 May.

Hengaw (Kurdish rights monitor)

Hengaw documented three judicial executions and the detention of Kurdish writer Majid Karimi in Tehran on 19 May, establishing Khorasan Razavi province as the newest geography in Iran's wartime judicial record. The organisation's Norway-based operation continues to surface a domestic repression track running in parallel with every diplomatic and military development.

India

Six India-flagged vessels conducted a coordinated cluster transit under PGSA bilateral assurances during the 17 May window, paying no yuan tolls. New Delhi's inclusion in Iran's state-to-state passage track insulates Indian energy supply without requiring endorsement of the PGSA's yuan-toll architecture or alignment with the US coalition.

Pakistan

Pakistan is the only functioning diplomatic bridge between Tehran and Washington. Its role is relay, not mediation in the settlement sense: it conveyed Iran's 10-point counter-MOU in early May, relayed the US rejection, and is now passing 'corrective points' in the third documented exchange of this sub-cycle without either side working from a shared text.

UK and France (Northwood coalition)

Twenty-six coalition members have published no rules of engagement eight days after the Bahrain joint statement; Lloyd's underwriters have conditioned war-risk reopening on written ROE from either Iran or the coalition. Italian and French mine-countermeasures deployments are operating on the in-water clearance task CENTCOM Admiral Brad Cooper's 90% mine-stockpile claim does not address.

Saudi Arabia

Riyadh has not publicly commented on the Barakah strike or the 50-47 discharge vote. Saudi output feeds the IEA's $106 base case; the $5 Brent premium above that model reflects institutional uncertainty no Gulf producer can compress through supply adjustment alone.
