Russian sanctions could be eased soon if Ukraine progress made - U.S. adviser

LONDON (Reuters) - Talks on easing sanctions against Russia imposed over the conflict in Ukraine could begin in the next few weeks, but more measures are possible if there is no progress over a ceasefire deal, the U.S. Deputy National Security Adviser said on Friday.

The European Union and the United States have imposed economic sanctions on Russia, with the West accusing Moscow of providing pro-Russian separatists in eastern Ukraine with troops and weapons. Russia denies the accusation.
