The anticipated meeting between U.S. President Donald Trump and Russian President Vladimir Putin in Budapest, intended to discuss a potential ceasefire in Ukraine, has become uncertain. The Kremlin announced on Tuesday that no specific timeline has been determined for the talks, indicating that further preparations are required. Kremlin spokesperson Dmitry Peskov said that “significant groundwork” is necessary before any meeting can take place. U.S. media reports suggest that Washington and Moscow still differ on the terms of a ceasefire. Russian Deputy Foreign Minister Sergey Ryabkov stated that it is “too early” to discuss detailed arrangements for the summit. Meanwhile, Russian Foreign Minister Sergey Lavrov recently held a phone conversation with U.S. Senator Marco Rubio, during which some disagreements reportedly surfaced. Moscow maintains that the understandings reached during the earlier Alaska summit remain valid and emphasizes the importance of implementing those agreements to ensure lasting peace in Ukraine.
