Friendship without boundaries?

Russia and China seem closer than ever notwithstanding the war in Ukraine. The Chinese leadership has refused to criticize Russia despite mounting pressure to condemn the Russian war of aggression against Ukraine. Just as Russia becomes economically and politically more reliant on its eastern neighbour, China is unwilling to give up years of trust building and forming a united ideological front against NATO and the US. At the same time, China is worried about being affected by the Western sanctions levied against Russia.
