Maya Kosyanchich said that the EU would keep closely watching the developments in the conflict zone.
Russian Foreign Minister Sergei Lavrov also expressed hope on Tuesday that the ceasefire regime between Kiev and militia forces would be consolidated in the near future.
"We will be monitoring the situation attentively. We do not want anyone or anything to hamper the implementation of the Minsk agreements," Lavrov said.
On September 5, Kiev officials and representatives of the self-proclaimed Donetsk and Luhansk people's republics reached a ceasefire agreement at a meeting in Minsk. The meeting was held two days after Russian President Vladimir Putin proposed a peace plan for eastern Ukraine, urging the conflicting sides to end offensive operations. He also called for the pullback of armed forces out of shelling range of civilian areas, an end to airstrikes, an exchange of all detainees, opening of humanitarian corridors, repairing damaged infrastructure and deploying international observers to monitor the ceasefire.
