Turchynov and Yovanovitch discussed the current security situation in Ukraine and intensification of cooperation between the two countries in the military and technical sector.
According to Turchynov, the Russian Federation is doing everything for the Donbas to remain the instrument destabilizing Ukraine and Europe.
"The Russian terrorist groups are making every effort to disavow and disrupt the Minsk deal," he added.
The sides also tackled the issue of military and technical cooperation in the context of military challenges Europe and the Middle East were facing, which also posed threat to the security of the whole world, as well as joint measures to combat international terrorism.

"We are interested in the continuation and deepening of cooperation," she stressed.
