Trilateral loses venue, keeps deadlock

3 min read

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.

    Immediate · Assessed
  • 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.

    Short term · Assessed
  • Precedent

    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.

Different Perspectives
Oil markets and Lloyd's of London
Oil markets and Lloyd's of London
Brent fell to $89.25 on ceasefire probability, not new barrels, with traders voting for Trump's deed over Tehran's denial. Lloyd's has not repriced Hormuz war-risk cover because its trigger requires a UN Security Council resolution or government certification, so tanker insurance costs remain elevated regardless of the spot move.
Pakistan and Qatar mediators
Pakistan and Qatar mediators
Pakistan's Mohsin Naqvi was in Tehran for his second visit in under a week, using the Pakistan-Qatar channel that delivered April's ceasefire after an identical public-denial cycle. The channel carries both civilian and military buy-in from Islamabad, the only configuration Iran's split command cannot dismiss as a partial signal.
India
India
India summoned the US Deputy Chief of Mission after three Indian sailors were killed aboard MT Settebello, the first formal grievance from a major non-belligerent directed at US enforcement. Indian seafarers supply roughly 12 per cent of the global maritime workforce; their presence on third-flag Gulf tankers is structurally inevitable regardless of bilateral diplomacy.
Islamic Revolutionary Guard Corps (IRGC)
Islamic Revolutionary Guard Corps (IRGC)
The IRGC declared Hormuz closed on 11 June while civilian negotiators were on the same mediation channel, then issued no public comment on the MoU framework. Its silence on the framework, rather than any foreign ministry statement, is the operative approval signal; the corps' unilateral Hormuz closure shows it did not treat the diplomatic track as binding on its operations.
Iran foreign ministry (Baghaei)
Iran foreign ministry (Baghaei)
Esmail Baghaei told IRNA that reports of a finalised deal were 'merely speculation' and that Iran had 'not yet made a final decision'. The denial is structurally identical to Iranian foreign ministry statements during the April ceasefire talks, which produced a binding text within 48 hours of the same language.
Trump administration / CENTCOM
Trump administration / CENTCOM
Trump cancelled the third strike day and called the MoU 'very strong' and almost ready to sign, while CENTCOM kept tanker enforcement running in the same 24-hour window. The administration is simultaneously withdrawing the military pressure it claims drove the deal and sustaining the enforcement campaign it is trying to trade away.
