Peace negotiations between Russia and Ukraine remain at a standstill, with no significant progress expected in the near future, according to Kremlin spokesperson Dmitry Peskov. Recent talks in Istanbul saw Ukraine call for a full and unconditional ceasefire, a demand Moscow rejected. Both sides did, however, agree on prisoner exchanges and exchanged peace proposals. Peskov emphasized the complexity of the situation and dismissed hopes for a quick resolution. He also said a summit involving the presidents of Russia, Ukraine, and the U.S. is unlikely unless negotiators reach a substantial agreement. Moscow is demanding a troop withdrawal from four Ukrainian regions as a precondition for ceasefire, while Ukrainian President Volodymyr Zelensky insists on a full and unconditional truce.
