I don't know why I feel repulsed whenever I see a mention of China in relation to cryptocurrency, anywhere. I guess it has to do with how China let this industry down by banning crypto activities in that country in 2017. That action was one that hit me hard at the time as a newbie in this industry. Then China was in a lead position in the space with lots of mining hash from there. That was then. In today's reality I don't think anyone should as little as accord China a second thought once this industry is concerned.
Going by the population of China and their technological advancements, China has the potential power to take control of the Bitcoin technology if they chose to. I am saying this on the basis of the two factors I mentioned earlier, which are the population and the advancements in the technology of the country and amongst its people. Although, we do not know the founder of Bitcoin by identity due to his anonymity, however, from his name, Satoshi Nakomoto, he is an Asian by thoughts and could have come from those axis. Interestingly, China is great enough to take charge of the financial technologies but may not be able to do so, because the government in itself have banned the adoption of such.
