Ukraine and Russia have agreed to implement a “full and comprehensive” ceasefire in eastern Ukraine by the end of 2019, after top-level talks.
Russian President Vladimir Putin and Ukraine’s Volodymyr Zelensky met face to face at a Paris summit on Monday.
Mr Zelensky was downbeat, saying little had been achieved at the meeting and he had wanted to see more resolved.
Five-and-a-half years of fighting between Ukrainian forces and Russian-backed rebels have cost 13,000 lives.
The negotiations were brokered by the leaders of France and Germany.
They follow a big prisoner swap and the withdrawal of Ukraine’s military from three key areas on the front line.
