Efforts to arrange direct negotiations between Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy have reportedly stalled, with officials suggesting that the complexity of security guarantees for Ukraine remains a key sticking point.
According to Reuters, the talks had been expected to follow a series of summits convened by US President Donald Trump earlier this summer. However, progress has been limited and attention has shifted toward wider diplomatic engagement led by US Secretary of State Marco Rubio.
Rubio’s European outreach
The US State Department confirmed that Rubio held discussions on Monday with senior European counterparts, including UK Foreign Secretary David Lammy, Finnish Foreign Minister Elina Valtonen and EU foreign policy chief Kaja Kallas, the State Department said in a statement.
The talks, which also included Ukrainian Foreign Minister Andrii Sybiha, were aimed at exploring the contours of a potential negotiated settlement. A readout from the State Department indicated that the officials had agreed to maintain close coordination on strategies to end the war.
Ukraine seeks binding guarantees
Minister Sybiha reiterated that Kyiv’s priority remained the establishment of firm and legally binding security guarantees. Writing on X, he noted that Ukraine considered such guarantees to be multidimensional, spanning military, diplomatic and legal commitments.
He emphasised that the Ukrainian military would continue to serve as the cornerstone of national security, making its strengthening a top priority. Sybiha also expressed appreciation for Rubio’s leadership in the discussions and praised President Trump for what he described as “peacemaking leadership”, Reuters reported.
US role in broader settlement
The White House has positioned Rubio as a central figure in shaping a framework for Ukrainian security assurances. According to administration officials, Trump had tasked the Secretary of State with leading the dialogue after his separate meetings with Putin, Zelenskyy and European leaders earlier this year.
Despite these efforts, the delay in arranging direct Putin–Zelenskyy talks highlighted the obstacles that remain. The divergent expectations between Moscow and Kyiv, particularly around the nature of security commitments, continued to complicate prospects for progress. For Europe, unity would be critical in sustaining diplomatic pressure and ensuring any eventual settlement was durable. For now, although discussions would continue, the timeline for high-level negotiations remained uncertain, the State Department said.
