No, logistics kills. It's 5000km from the Caspian coast to where oil is needed in china. And in general, Russian logistics sAck. I remember watching Thamoas Sowell, famous American economist, pointing to this. It's just so expensive and time consuming to transport goods from one part of Russia to another.
I have noticed the west really struggle to understand the value of something beyond first order costs.
The cost of oil shortage isn't the higher price you pay for extraction or transport, it's the value of economic activity lost from not having oil.
The "expense" of transporting goods from one part of Russia to another is trivial compared to expense you pay from not having oil. When you're the only one who can access Russian oil, it doesn't matter how much you pay for transport because you can always make a profit reselling it to someone who will pay whatever you demand.
Famous American economist also like to claim the cost of infrastructure isn't worth it because it doesn't directly generate 1st order profit, they're the same people who would argue agriculture is unimportant because it makes up a tiny fraction of GDP, but we all know the value people actually attribute to having food is far higher than it's nominal value on the market.
