So quite logically, the community of bitcoinners there is quite large... Just because there are more people in the country than in many others. So, the community is large and each time the government makes an annoucement, of course, many people are directly affected by what has been decided.
Thus, you have this effect of "bad news" whenever there's a statement from the Chinese government.
Though, actually, what China does and says and so on, does not directly have impact on bitcoin. The impact exists only because some people (Chinese I guess but not only) start panic selling and buying when there is any statement from China.
So China is not a threat, just an indicator!
