Isn't oil price increasing good for Russia though? Their oil isn't as cheap to extract so price increasing multiplies their profit very significantly if they can find a buyer.

The sanctions being levied against them will impair their ability to sell to a large portion of the world, including current (well, now former I suppose) trade partners in Europe. While they could try to undercut the global price in order to make their oil more appealing to remaining trade partners, it's going to be a challenge depending on how the current and future sanctions develop to even get to market.

A quick search gives this as the answer to who their largest oil buyers are: China, the European Union, South Korea, India and Japan.

China will do what China wants here. But South Korea, Japan, and the European Union will end up being harder to sell to, if possible at all, in the near future. India is a toss-up, depends on how they decide to participate in all this.

Yes. From Putin's POV: two mehs and one thumbs way up

Hefty increases in oil prices have a way of changing people’s minds. Particularly people who don’t normally care about politics.

That would mean a softening on Russia taking the Ukraine. It's not Russia driving the increase in prices

Can you expand on that? Russia's main export is oil.
