Kiev: US Vice-President Joe Biden on a visit to Kiev warned on Friday that Russia risked further isolation over its "unacceptable" aggression in Ukraine.
"It`s simply unacceptable in the 21st century for countries to attempt to redraw borders by force... because they don`t like a decision their neighbour has made," he said after meeting Ukrainian President Petro Poroshenko.
He warned that Russia had failed to fulfil its commitments under September`s Minsk agreements, adding: "So long as that continues Russia will face rising costs, greater isolation."
