Russia is selling to China and India at a huge discount.
Thats petroleum. One can buy and store oil, and change suppliers at a whim. There doesn’t need to be an ongoing relationship. If India and China can get discount oil, great.
But this is about gas though. Fundamentally different. This is a utility service, not fungible commodity trades. Once the seller and buyer commit, and lay pipe and build gas fired power plants, etc., there is no easy way out of it.
