In this case, China is coming into its own as a regional hegemon, assuming their relatively new status as an outright dictatorship doesn't fuck that up.
China has been an outright dictatorship for a while now, it's just the lifetime leader that was recent.
You're right, words do have meaning. Just because there is a transition from one dictator to another without bloodshed or death doesn't mean it isn't a dictatorship. Just because the dictator of the week is chosen by a committee doesn't mean it isn't a dictatorship. One-party systems are commonly accepted to be dictatorships because of the lack of ability by the people to choose their leader, rather it is chosen by the party (usually the party elites).
