Russia rejected a cease-fire proposal linked to a U.S. peace initiative following a phone call between President Donald Trump and President Vladimir Putin.

The disagreement stalls a high-level diplomatic effort to end the conflict in Ukraine and has led to the postponement of a scheduled summit.

President Trump and President Putin spoke on Monday for more than two hours [1]. Following the call, conflicting reports emerged regarding the Kremlin's position on a cessation of hostilities. Some reports indicated that Russia remained open to a cease-fire and expressed a desire to resume trade with the U.S. [1].

However, other reports state that Russia rejected an immediate cease-fire in Ukraine [2]. This rejection has sparked a dispute between the two nations, culminating in a clash at the United Nations on Tuesday.

Because of the friction over the peace terms, the planned summit between the two leaders was put on hold on Tuesday [2]. The dispute centers on the conditions of the peace initiative, and whether a cease-fire can be achieved without specific concessions.

The U.S. administration had signaled that the Monday call was a productive step toward a resolution. Despite the length of the conversation, the subsequent rejection of the cease-fire proposal suggests a significant gap remains between the two governments on the terms of a peace deal [1], [2].

Russia rejected a cease-fire proposal linked to a US peace initiative.

The contradiction between the perceived success of the diplomatic call and the subsequent rejection of the cease-fire highlights the volatility of current US-Russia negotiations. The postponement of the summit indicates that the disagreement over the immediate terms of the conflict's end is substantial enough to halt direct face-to-face diplomacy.
