The likelihood of a summit between Ukrainian President Volodymyr Zelensky and Russian President Vladimir Putin is increasingly uncertain as diplomatic overtures stall, just days after Donald Trump expressed optimism about the meeting. Various locations including Geneva, Vienna, Budapest, and Istanbul have been suggested as venues for the talks, but significant political and procedural hurdles remain.

As of now, Zelensky and Putin have not met in person since 2019, prior to the onset of Russia's full-scale invasion of Ukraine. Trump's statement that he had commenced arrangements for the summit came shortly after his phone conversation with Putin, during which they discussed "the possibility of raising the level of representatives," according to Kremlin aide Yuri Ushakov. However, the vague and cautious nature of the Kremlin's remarks suggests that real progress is far from assured.

German Chancellor Friedrich Merz speculated that a summit could materialize within the next fortnight but expressed doubts about whether Putin would attend. Trump hinted at serious consequences for Russia should there be an avoidance of cooperation in peace talks but provided little clarity on what those consequences might entail.

The Kremlin appears to be conditioning any potential meeting on very strict pre-agreed terms, which could clash with Ukraine's positions. Russian Foreign Minister Sergei Lavrov’s remarks indicated that Putin is ready to meet with Zelensky but under the condition that all prior "issues" are resolved, a term long employed to sidestep dialogue with Ukraine.

Zelensky, in contrast, has articulated that any meeting must follow the establishment of security guarantees agreed upon with Kyiv's allies, which Moscow is unlikely to accept. The two nations remain entrenched in their long-standing stances, accusing each other of obstructing peace efforts.

While Budapest is emerging as a favored venue for a potential meeting, critics point out that Hungary's government has not strongly supported Ukraine. Prime Minister Viktor Orban’s ties with Putin and his previous blockades against Ukrainian EU membership raise concerns about Hungary’s neutrality in facilitating a productive dialogue.

Other potential host countries, such as Switzerland and Turkey, are being considered as well. Switzerland offers a history of neutrality and peace talks. Turkey has also had prior engagement with delegation talks between Ukraine and Russia.

Amid these diplomatic discussions, the ongoing conflict in Ukraine gives little indication of resolution. Recent strikes by Ukrainian forces against Russian territories and a significant uptick in Russian attacks in Ukraine demonstrate that hostilities continue to heighten, reflecting a grim backdrop for any proposed summit. Zelensky reiterated on social media that pressure on Moscow is vital for meaningful negotiations, as the situation remains precarious.
