2. Regarding the real reserves of China and Russia - no one doubts that there is a huge gap between their statements and the real state of affairs
might want to check the BIS website.. not social media
its not a YUANIZATION
its not a scenario of all countries using the YUAN
its instead multiple CBDC collectively swapping via an m-bridge with no single "reserve" master currency
each country has its own CBDC
I agree, English is not my native language, and maybe I did not convey the main idea very well. I will try to explain it more simply. I wanted to say that over the last 2 years, China has been trying to promote its yuan to the BRICS countries, while actively promoting another topic - de-dollarization. You can simply find information in the interval 2022-2023, where China, at every opportunity, says "let's transfer settlements between us - in yuan", "our strongest economy is behind the yuan - it is more stable than the US dollar", "the dollar is not stable, the yuan is more flexible, we will help you all" - these are their open proposals. But what I completely agree with you - China has been suggesting other countries to abandon the dollar, while not abandoning the dolar itself !
A good example is when China sold the "very stable yuan" to russia for, you guessed it.... DOLLARS, after which, in 3 months the yuan suffered a very bad inflation. Losses of Russia - tens of billions of dollars, respectively - the same level of income of China, on the very process of "dedollarization".
