Well, for that to happen... other countries currently supporting the US Dollar would have to agree to that and pledge their support for the Chinese Yuan or the digital equivalent of it.

China being a communist country with an oppressive government will not count in their favour to get other countries to agree with that.
On top of that, many countries are also blaming China for the coronavirus. I cant see them doing a 180 degrees turn to accept China as their new financial master.
