I was surprised to learn that China seems to be complying with at least some sanctions against Russia:
China has refused to supply Russian airlines with aircraft parts, an official at Russia's aviation authority was quoted by Russian news agencies as saying on Thursday, after Boeing and Airbus halted supply of components.
Agencies including Interfax quoted Valery Kudinov, a Rosaviatsia official responsible for maintaining airplane airworthiness, as saying that Russia would look for opportunities to source parts from countries including Turkey and India after a failed attempt to obtain them from China.
But... why would they do this, given their official stance supporting Russia? Wouldn't openly refusing to respect the sanctions be a great power move to defy Western influence? I do understand that they might still help Russia go around the sanctions in secret but why not do it openly for the whole world to see?
