Of course the Chinese government doesn't want the Yuan to become the single international reserve currency. Being a reserve currency is bad for your manufacturing sector (that's one of the reasons why the US barely has any working factories any more), so China will want to limit how many reserves other countries hold on to. But the world doesn't need a single reserve currency, the only beneficiary of having a single reserve currency is the USA, who alone in the world can just print more dollars and have other countries pay for them, in effect passing their inflation onto other countries as debt.

But the Chinese government would certainly like to trade in yuan, and that's what is already happening. As of 2022, only 40% of international trade is still in US dollars. Most of the rest is in yuan, euros, yen and rubles. Expect the amount of trade in local currencies to increase rapidly as more countries realise that trade in US dollars benefits nobody but the US, and leaves them vulnerable to theft and blackmail ("sanctions") by US and European banks.

In terms of global currency reserves, the world is rapidly dropping the dollar and forging new trade deals outside of the post WW2 US-dominated Bretton Woods system. Why should they continue propping up a rogue state's military? Global currency reserves of the US dollar have dropped from 71% of the total reserves in 2000 to 59% in 2022, and then plummeted another 12 percentage points to just 47% so far this year. Countries all over the world are getting rid of their dollar reserves. Of course, they don't want to do it too quickly, for very real fear that the US will give them a short sharp dose of freedom ("you're free to work for the benefit of the US, or you're free to die, its your choice"), like they did Libya and Iraq.
