"We call on Russia to contribute to the de-escalation and draw back the additional troops from the border (with Ukraine)," Wirtz said.
The representative of the German government pointed to the need to continue a "political dialogue" in order to find solutions to the conflict in the east of Ukraine, in particular within the framework of the international contact group.
Commenting on the Russia's proposal to send a UN humanitarian mission to the east of Ukraine, Wirtz noted that "at the moment there are no legal grounds (for that)."
Also, the German government called on the Russian government to refrain from taking steps that could lead to further escalation of the conflict in Ukraine, deputy spokesman of the German Foreign Ministry Sawsan Chebli stated.
"We demand maximum transparency and call on Russia to refrain from any steps that could lead to further escalation," the diplomat said.
According to her, such steps of escalation, in the view of official Berlin, include the current Russian military exercises and the increased concentration of Russian troops at the border with Ukraine.
