The chinese is going to end up dominating the Bitcoin ecosystem unless the idiotic governments on the rest of the countries don't wake up and start being 100% pro Bitcoin and dropping billions on VC (as well as buying actual BTC as a form of collateral when their fiat fails).
Other than mining and questionable exchanges, it really doesn't look like there is any type of ecosystem in China remotely comparable to the US. There's nothing you can do with in China other than mine or trade it. There's no commerce, hardly any full nodes and I can't think of many or any Bitcoin innovations that they've come up with. If the government did give a cautious blessing then look out.
You are probably right. Speculation is still primary concern and we are short of development talents especially with BAT absorbing most of the developers in China.
As far as I know, they deployed full nodes at servers outside China.
In terms of innovation, we are happy to see that the flourishing of startups in China with blockchain.
8btc had a meetup last weekend with reps from major VCs in China. Below is the live coverage(in Chinese) but you can always understand the pictures.
