Ties with Russia to be top focus at NATO summit in Warsaw
The diplomat said relations between Russia and NATO will be among the focal points at NATO’s summit in Warsaw in July 2016.
"Relations with Russia and the way NATO will be positioning itself towards out country will be among the focal points," he said, noting that NATO was not interested in finding itself "in a spiral that will lead to a new Cold War."
"The Alliance is far from homogenous. It is absolutely obvious, and this can be seen in many speeches and media reports, in analytical materials - there is a number of countries that proceed from the fact that it is impossible to build a full-value security system that would be more adequate without having Russia as a partner," Grushko said.
