China has been doing very well in terms of economic development and growth, and I believe that this is how a countries currency gets valuable, but for China to stand up now and want their yuan currency to replace united states dollars, I won't say it's impossible but its definitely not going to be an easy one, and even if this is ever going to happen, it will take several tens of years, the entire would have already recognized united states dollars as the global currency, it will take a lot of time to change this.
