2. there might've been something, but nothing serious - if this doesnt work

You guys remember the incident with major trojan network? China and Russia were accused. Communist China of course responded in rather strict manner as is common and basically said that its a delusion of someone with cold war mentality. Basically pretty destructive response, even if it did not really change the way the world looked at it.
How did Russia respond? "Dunno."
