European Union foreign policy chief Kaja Kallas said on Monday that the EU will work on a 19th package of sanctions against Russia and warned against concessions to Moscow.

"As far as Russia has not agreed to a full and unconditional ceasefire, we should not even discuss any concessions," Kaja Kallas said.

But considerable distance remains between the positions of Ukraine, Russia and America, as well as doubts about Mr Putin’s real intentions. For now his bombardments continue. The shape of the peace deal the three countries are working on is hard to pin down.

President Donald Trump described his summit Friday with Russian President Vladimir Putin to discuss the war in Ukraine as a “feel-out meeting.”

Russian forces have made a sudden thrust into eastern Ukraine near the coal mining town of Dobropillia, a move that may be an attempt to increase the pressure on Kyiv to give up land as the U.S. and Russian presidents prepare to meet.
