European Union institutions are assessing the legal, logistical and political implications of a proposed meeting in Budapest between US President Donald Trump and Russia’s Vladimir Putin, following reports that the encounter is being prepared in the Hungarian capital.
Several EU sources privately characterise the prospect as a “political nightmare”, chiefly because the two leaders would discuss the war in Ukraine on EU territory without the Union’s participation.
Publicly, Brussels has struck a cautious note. A European Commission spokesperson said any meeting that tangibly advanced a just and durable peace in Ukraine “would be welcome”, while noting that Putin is subject to EU asset freezes and that decisions on airspace or facilitation rest with member states.
There are reports that Hungary has indicated it will ensure Putin can enter and depart for such a meeting, despite the International Criminal Court warrant and the ban on Russian aircraft in EU airspace imposed after the 2022 invasion.
The venue raises practical questions. Putin is under an ICC arrest warrant, and most EU airspace is closed to Russian-flagged aircraft. Any journey to Hungary would likely require exemptions by one or more member states or a longer routing via non-EU airspace. While entry to the EU is not per se banned, overflight by Russian aircraft remains restricted and national authorities would have to decide on any derogations.
Budapest’s selection also carries political sensitivities. Hungary maintains warmer ties with Moscow than most EU capitals and has positioned itself as willing host. Prime Minister Viktor Orbán welcomed the choice, presenting Hungary as a suitable location and signalling it would not act on the ICC warrant. The choice of Budapest could accentuate intra-EU divisions over Russia and potentially offer domestic advantages to Orbán ahead of elections.
The White House dimension is in flux. Trump said after a 16 October call with Putin that the two intended to meet in Hungary, and US media and agencies have since described preparations under way. The Budapest plan was announced as President Volodymyr Zelenskyy prepared to press his case in Washington for additional capabilities, including Tomahawk cruise missiles. At their 17 October meeting, Trump signalled reluctance to provide Tomahawks, citing US stockpile needs and an emphasis on diplomacy.
For Brussels, three immediate files are clear:
Air and legal clearances. Any overflight or arrival by a Russian state aircraft would test the interaction between EU sanctions law, national discretion over airspace, and treaty obligations under the Rome Statute. The Commission has said member states hold the pen on airspace decisions, while the ICC warrant remains operative unless and until a national authority determines otherwise.
Institutional involvement. An encounter that excludes Kyiv and the EU risks perceptions of marginalising stakeholders whose security is directly affected. EU officials had sought a role at the table; absent that, officials must decide how to shape parameters around any talks, including reaffirming the Union’s conditions for a just peace.
Political signalling. Hosting a US–Russia bilateral in an EU capital while fighting continues could be framed by Moscow as tacit validation of its position. The choice of venue is potentially awkward for both the EU and NATO, given Hungary’s distinct stance on Russia.
The timeline remains uncertain. Reporting indicates that adviser-level discussions are envisaged ahead of any leaders’ session, but no date has been announced. The choreography—participants, agenda and format—will shape how European capitals respond: whether by facilitating travel, by setting political guardrails, or by declining exemptions that would be required for a Russian state flight.
In parallel, Washington’s signals will be closely read in Europe. Any meeting that prioritises a ceasefire along current lines without addressing Ukrainian sovereignty and security guarantees would sit uneasily with the EU’s stated position since 2022. Commission statements have emphasised the goal of a “just and lasting peace”, while member states continue to support Ukraine militarily and financially.
If the Budapest meeting proceeds, it would be Putin’s first appearance in an EU capital since the full-scale invasion began. It would take place under the constraints of sanctions, the ICC warrant and active hostilities, with aviation and legal arrangements under scrutiny. Whether it becomes a substantive diplomatic engagement or a largely symbolic encounter will depend on decisions taken in the coming days by Washington, Moscow and EU capitals.
