"We were ready to discuss, then they discarded it, wanting to gain an advantage on the battlefield and achieve a strategic position. Well, now here are our conditions. Have they gone crazy? Why would we? Undoubtedly, we will base our actions on the realities on the ground," he said.
"We must understand with whom and how we can engage and whom and to what degree we can trust. We are of course analyzing everything that is going on," Putin told reporters.
"They do not invite us. Moreover, they say that they do not see us there," Putin said at a press conference.
"It is clear what this event is all about: bringing together as many countries as possible to claim that they have everything agreed on and then giving Russia an ultimatum," Putin said, adding he would not have it.
