Well, China knows that they can stand on their own. Just like what they did with various applications not adopting it but instead, they would create their own so that they would be independent and they have proven it that they can make it. It is the same with blockchain wherein they would study the importance of it and then create something out of it that is their own and not being dependent on others. Their country do not have facebook or google because they have their own and I am sure that they would have their own cryptocurrency too.
