China's growth in any technology regarding minerals is only ONE aspect of China's growth plan for global sovereign and global prosperity.
China Brazil Russia and other countries who are becoming creditors, join the BRICS centralized form of global economic growth, to obtain the opposite of "hegemony".
China has decentralized its banks. Their banks are small businesses, and this is why China is thriving. More about their banking system in the comments line.
What China wants is open trade, greater global prosperity in sovereign countries, and rich customers, because China is the greatest producer of any goods in the world, and needs lots of trade, and lots of rich countries to participate. USA could be one of them, but it is controlled by a few who don't want this.
The ones who control the FED, And Euro Bank, IMF , Bank of England, World Bank... want a "single world order" which is precisely what BRICS stands against.
In this article you can see a small example, of how they don't use a currency as their basis for trade, but rather a mutually prosperous outcome which does not create debt slavery which is what the Federal Reserve, IMF, etc use to enslave humanity by instigating war and creating "boogie men" propaganda.
The last thing these enslavers want is for the true information to be disseminated.
