Your geopolitical views are so naive it's hard to take seriously.

EU is now an unwilling dumping ground for China, hostility and paranoia are growing by the day now that China is no longer a lucrative market itself and is pursuing its interests outside commerce, the cordial days are numbered.

Russia would never be subservient to China, once the war ends Russia would be back being a geopolitical player because of its vast natural resources, and they are already import substituting even Chinese products.

Russia can turn to the west to be a real western country whenever they see fit, the eternal fear for China.

This is why China is going as far as it can to accommodate Putin, even souring it's relations with the EU which isolated itself.

In this sense, it is China being "subservient" to Russia.
