It is always the Chinese :)
I think it is China way of saying we need to firewall them in rather than have the expense borne by the Chinese government for the Great Firewall of China.
Which is oddly a bit like the irony of the Original Great Wall of China, which was really designed to keep the Chinese in, by the third build.
China is going to be a force to reckon with, is already, and they have limited the birth rate, which is on the face of it a good move. The jostling is about who is the world superpower, can the US better the Chinese in the cyber plane, well so far no.
