President Obama spoke with Russian President Putin today about the situation in Ukraine. President Obama welcomed President Poroshenko’s peace plan and urged that Russia and separatist leaders work closely with the Ukrainian government to take concrete steps to implement it. The President called upon President Putin to press the separatists to recognize and abide by the ceasefire and to halt the flow of weapons and materiel across its border into Ukraine. The President emphasized that words must be accompanied by actions and that the United States remains prepared to impose additional sanctions should circumstances warrant, in coordination with our allies and partners. The President and President Putin also discussed the removal of chemical weapons in Syria and ongoing efforts to reach a comprehensive solution to ensure that Iran’s nuclear program will be exclusively peaceful.
