If they manage it properly that is, as in: not print mountains of it, and not using it to enforce their political aims.
They're currently actively busy making the Renminbi reserve and default trading currency in much of Asia.
And, as a last resort, there's always Bitcoin and gold, although, as Ghana will discover (unless they make the mistake of using a 3rd-party custodian) gold is very tricky to move about.
Ah yes, the CCP, famously known for not enforcing political aims.
You also have Xi next month meeting Arab leaders in Saudi Arabia, a lot of people are expecting a PetroYuan announcement or at the very least the foundation of such an agreement. I think after those two events are handled and closed, China should be in an excellent position to become Asia's major energy hub. They can get Russian, Qatari, Central Asian stans and Saudi energy products without having to use Western financial institutions or services. I think the Russian and Arab leaders want a bigger share of the Chinese bonds and financial markets so they can grow their RMB reserves like they are already doing with their dollars.
Ghana going with gold for energy imports seems smart for now but yeah moving gold isn't easy, also verifying the gold is also not easy. That's why i think BRICS+, SCO and BRI nations will create a block chain with a digital currency(Central Banks digital Currency) backed by a basket of currencies and commodities to facilitate import and export and government to government financial transactions.
