The obsession with China is something that will not disappear so soon, because a lot of people still think that China is in some way necessary for Bitcoin to succeed - of course because it is the most populous country in the world and because they are already (or will become) the first world economy. What they all completely ignore is their political system, and only those who have not experienced the evil of communism still have some hope that China will accept Bitcoin in one way or another.
The best thing that happened was that Bitcoin was banned in that country, because China has actually been one massive weight around Bitcoin all this time - we can finally move forward without listening to what comes next from that country.
I like to underline your sentence, I totally agree with the title of China politics in running the world financial and economic system. We saw how China easily toyed with the economic cycle by launching news, then had time to destroy the price of Bitcoin. After a while, then another statement appeared about withdrawing the Bitcoin mining block on the pretext that it would support it again.
We are indirectly following China political game. Even the world is also carried away by its political playing. That way China is confident, already feels that the world economy depends on its statements.
