If they created sanctions to prevent the fuel from being resold then it would be worth even less. That would be a footgun. I don't think China or any other country is going to give Russia the ability to audit their oil sales, which would be required to ensure compliance with a reselling deal. There's no incentive for the reselling country and again it would make the Russian oil worth less.
