China will constantly try to supplant the dollar or any other foreign currency. It is a normal and natural process. The struggle for the dominance of their own currency occurs in all states. But the outcome of this struggle directly depends on the state of their economies, territory, population, availability of natural resources and other factors. In this regard, China has many advantages over the majority of states. Economic, trade and financial wars between China and the US have been going on for a long time. Who will win here and who will oust whom, we cannot know. These wars will continue for a long time to come, with varying success.
