Do you know how that supply is making it to china? Almost all of the pipes go from Russian oil fields west to Europe. Even the pipelines that travel east have to contend with a reality that Nobody lives in the Gobi desert. Instead what is happening is oil is being shipped by boat to non-aligned parties like India and China. Supposedly using ship-to-ship transfers[1] to obscure origin, or because Russian ports can't support supertankers.
And all of the PLA's ambition is in the South China sea, which means even if you rely on Russia to supply you wartime energy, it has to ship through a battlefield. And anyone opposed to it has a pretty free hand to say "mine now" as the path meanders by Turkey, Egypt, Saudi Arabia, Yemen, India, Singapore, Indonesia, the Philippines, Sri Lanka etc.
