As OP said China hadn't grown out of making some cheap politics between the powers, it have got the strong manufacturing setup which is the reason it have emerged as one among the strong economy in the last 20 years. USA also a reason, to suppress the supreme power of Russia media started to compare between China and USA which too helped them in the growth.
China has always looked for its own benefit. Its tactics has led it to where it is right now. Currently, China is the world's second-largest economy. And it could become the largest economy in the world if it continues to do what it's doing. By adopting crypto/Blockchain tech, China could get the tools/knowledge it needs to help strengthen its CBDC (digital Yuan). It can also collect huge taxes along the way. China is not stupid, unlike the US that recently went aggressive against the industry.
If America continues to reject crypto, then it will be left behind in the dust, paving the way for China to take over the world. Crypto is the future whenever governments like it or not. Let's see how everything will play out in the long run. As long as crypto stays decentralized, nothing else matters. Just my thoughts
