Both probably play a role in the equation of how China and the PRC has acted thus far in the wake of the disease. I certainly don't think China is acting with some far greater knowledge of the virus than other affected states/countries. The virus genome has been mapped and the world is working on developing a vaccine (I believe I read a recent story that Hong Kong claims they developed one). Unfortunately (or perhaps fortunately), any kind of vaccine will need to go through phases of testing and validation to ensure its efficacy and this process will inevitably take time. That time will regrettably see more people fall victim to Covid-19.
Of course, China was also probably worried about the economic and political repercussions of appearing to the world as not being strong or proactive enough in its response. So much of the global supply chain relies on China that even having the resemblance of not being in control of the situation would have produced a far greater economic bloodbath than we've seen thus far.
