If China really is a socialist country or one pushing towards communism, why do you think they are waiting to push more directly in that direction? What is to be strategically gained from capitalizing your economy, essentially going backwards for 50 years instead of continuing to push for communism?
I believe that Xi Jinping has stated that about 2050 is when China would start to move towards socialism. Now, even if you believe that he is being genuine, he would be about 100 years old by that point. In all likelihood, he would no longer be President or the head of government, if he would even still be alive.
The question becomes: will his successor try to implement socialism? Certainly, that is possible, like anything. Of course, there could be a significant amount of people in positions of power who have the view of "We got this powerful this way, why change it?".
