This was announced by Russian Foreign Ministry spokesman Alexander Lukashevich at a briefing on Friday, Censor.NET reports citing UNIAN.
"Russia's attitude to this is very negative. We will be monitoring the situation at the summit in Riga, but it is already obvious that our reaction will be quite tough and principled. We see which direction this 'partnership' is moving to and which shades it has been acquiring if one looks at the positions of scheduled participants, primarily those from the European Union," he said.
According to him, the word 'partnership' has "definitely an explicit anti-Russian connotation."
