Ukrainian and Western leaders say that Russia has not kept up its part of the deal
The White House is pushing for implementation of a deal to end the conflict in eastern Ukraine before President Barack Obama leaves office, national-security adviser Susan Rice has said.
While recent peace talks involving Russia and Ukraine have been unproductive, the former United Nations ambassador who now coordinates foreign policy at the White House said that she sees the potential for a resolution by the end of the year.
Obama is due to leave office on January 20.
