Russian President Vladimir Putin and Ukraine’s President Volodymyr Zelensky met face to face in Paris on Monday.
Both sides have also agreed to release and exchange of all “conflict-related detainees” by the end of the year.
They pledged to disengage military forces in three additional regions of Ukraine by the end of March 2020.
Additional talks will be held in four months to take stock of the ceasefire’s progress.But Russia and Ukraine continue to disagree on issues such as the withdrawal of Russia-back troops, and elections in areas of Ukraine held by separatist rebels.
Five-and-a-half years of fighting between Ukrainian government forces and Russian-backed rebels have cost 13,000 lives.
