Moscow has said any peace deal must take into account its security interests US President Donald Trump is growing impatient with Russia over resolving the Ukraine conflict, Secretary of State Marco Rubio has said. Moscow maintains it is open to diplomacy, but has said any settlement must take into account its security concerns.Speaking to Fox News on Saturday, Rubio claimed that while Trump is focused on peace and has done his best to bring hostilities to a close, his overtures to Russia appear to be yielding little result so far. “He’s done everything possible to bring it to an end. I think he is growing increasingly frustrated,” he said. According to Rubio, despite “good interactions with [Russian President] Vladimir Putin and phone calls, it never leads to anything.”“He is losing patience, losing his willingness to continue to wait for the Russian side to do something to bring an end to this war that wasn’t his, but he wants to see it come to an end,” Rubio added, accusing Moscow of using “delaying tactics.” Read more Trump’s ultimatum isn’t an ultimatum – and Moscow knows it His comments come after Trump imposed a 50-day ceasefire deadline on Moscow, warning of “very severe” new sanctions, including 100% “secondary tariffs” on countries buying Russian oil. Kremlin spokesman Dmitry Peskov warned that the sanctions threat would be interpreted by Kiev as a “signal to continue the war” rather than to seek peace. He has also described Trump’s style as “rather harsh,” while confirming that “Moscow intends to continue dialogue with Washington” and follow “a line of repairing the significantly broken bilateral relations.” Earlier this week, Russia and Ukraine held a third round of direct talks in Istanbul, with Moscow proposing short ceasefires for retrieving wounded and fallen soldiers. Additionally, the Kremlin offered to continue prisoner exchanges and return the remains of fallen soldiers.However, the two sides remain far apart on a potential peace settlement, with Moscow insisting that Ukraine should recognize the loss of five of its former regions that joined Russia in public referendums, withdraw its forces from them, commit to neutrality, and limit its own military capabilities. Kiev has dismissed the terms as an “ultimatum.”
