... ? Banal - significant Chinese banks began to actively block all payments from/to Russia, because of unwillingness to get sanctions and lose the Western market, on which the Chinese economy depends completely.
That is correct. Sometimes people forget how dependant China can be in terms of their economical growth of the western market and their western partners, specially when I see some topic/thread here in the forum badmouthing the United States Dollar anf insisting on the future of the BRICS new currency...
I still believe China is trying to keep some sort of equilibrium between their political alliance with Russia and the same time continue their economical relation with the west.
Part of the game is to continue to supply both North Korea and Russia with technology and military products (not money) while the Chinese Communist Party gets paid with energy (oil from Russian fields). Since there are not third party banks involved in those exchanges of goods, then there are not direct reprisals from the west, yet.
On the other hand, the United States and the west are also kind of dependant on the cheap labor China continues to offer to the world, USA has tried to replace or be least dependant of Chinese chips, but it is a very difficult task to compete with their prices, added to the fact their have the biggest deposits of rare minerals on the planet. Even if USA and the west tried to replace china's products, the price of them would spike and scare competition away.
China is not dependent on the West or vice versa, everything is based on mutually beneficial cooperation and no one wants to lose major business partners. That is why China has never intended to give up its relationship with Russia or its relationship with the West, they always seek to balance to bring the greatest benefit to themselves.
No one is talking bad about USD because it is still the world's dominant currency and some countries, especially BRICS, want to reduce their dependence on USD, or the ongoing de-dollarization process is also true. People just want and support a multipolar world instead of the unipolar world as it is today, but many stubborn people don't want to believe that and they don't want that to happen.
I believe that even in the event of war, these countries will still maintain a certain level of relationship for national interests, no one can be completely autonomous in everything because each country has its own strengths. The United States holds the semiconductor chip technology, but China is the country that holds more than 90% of the world's rare earths. They need each other, not one is afraid of the other.
