Chinese Central Bank already made statements that it will push the yuan internalization, that means that it won't artificially devalue the yuan in the future anymore.
I think that last yuan manipulation from the CB was in 2015, and from then, it stopped. Clearly because even then China realized that it will have to internationalize the yuan to fight the US hegemony and for that it needed to stop the devaluation first and be more open and clear in general. Maybe because the first Western financial sanctions against Russia were in 2014.
Yuan was also included in IMF SDR basket in 2016. That is also showing a clear sign of internalization pursuit.
Nowadays there are more and more green lights from CB for offshore yuan clearing and settlement services for more bilateral trade happening in yuan. There are also bilateral trade agreements that go together and drive that process of course. There are also currency swaps with other central banks around the world in the end.
China's commercial banks already started giving BRI loans in yuan, there are already yuan issued bonds abroad and opening of Chinese domestic yuan bond market too.
I'm not an expert, but I think the policy of China is clear enough, the only thing lacking now is time and more demand for yuan abroad, and then more yuan financial infrastructure will follow over the years ahead while demands also goes up.
Nowadays, I'm only not sure if it will be yuanization without appreciation or without it. If China wants to push the yuan abroad without it appreciating, then maybe they could simply print more currency with the demand going up to keep in the equilibrium. And since China, as a state, control its largest banks, it could be possible with some clever managment, its Central Bank and gigant commercials banks working together.
Generally, it is impossible to significantly internationalize one currency, without it strengthening as a product of that too, however, since China as a state controls its largest banks, maybe its possible with some new tactics. Or maybe with more creative usages of those already existing monetary tactics.
