US officials say Russia asked China for military support and help in evading sanctions. China is not going to provide military support. The US has said China will face "consequences" if it helps Russia evade sanctions. While China has obviously agreed not to help Russia to fight in Ukraine, the question China is asking is 'why should China join the economic war the West declared against Russia'? (“Who will assist China if (or when) it's China's turn to be sanctioned ?”)
