A more fundamental reading from my pov :
1. Ukraine conflict is due to US-led NATO expansionism. Russia hit back to defend themselves.
2. US and EU allies sanction Russia, thereby imposing cost on Russia's retaliation.
3. Sanctions have cost, in form of repercussion on US and EU economies. A loophole exist in form of China, who 1. not only in position to keep Russian economy alive, but 2. take advantage by filling in the gap left by western mncs.
West I China
Want : Uphold Hegemony I Want : More trade and opportunities(this is what russia need too)
Cost : Economy damage I Cost : Nil
Not only is US demanding China to give up on her basic right to trade with Russia, US is expecting China to share the cost of what essentially an act of sustaining US hegemony.
If China yield to the demand of US, this is equal to submitting to US hegemony.
