believe that most of the node operators are placing their nodes behind VPN, which ultimatively shows the node to be in different country.
There is no other logical explanation that i can think of in regards to such a low number of nodes there.

I agree. This ist most probably the problem. I'm not sure though that china is blocking bitcoin traffic really but it's not out of question.
I wonder if there is a way to get the real numbers then.
