I don't know who this guy is, but his response to a direct question is interesting. Although he was asked a very direct question: whether China signed a deal for the Su-35, he didn't answer the question. He basically said that the Su-35 has been a collaborative project between Russia and China. And after efforts from both sides, there has been some success. And both nations will continue to collaborate in a mutually beneficial way.
Why not just answer the question? It's already in the news everywhere...
that sounds pretty much like a yes to me.
LOL, you have to get use to the ways the spokesmen and spokeswomen from China foreign ministry/ defence dept. etc.. answering questions from news reporters. That is they standard response, no direct yes or no, but you can interpret that is affirmative.
And the S-400 sounds like an affirmative too! so China is getting both of these toys S-400 & Su-35. It really looks like Russia-China defense cooperation has definitely been upgraded to a new level.
