Unfortunately for Russia, the small pipelines in the East to China, are not connected to the fields that supply Europe, and they are too far away to connect (several time zones).
Those Western fields (about 85% of Russia’s former gas exports) are going to mostly shut down, and they will have to start over to build new fields in the East and pipelines to China, as best as they can.
Raising exports to China by 63.4% may sound good, but is only about 1/10th of the commensurate reduction in Russia’s former exports to Europe.
Overall, Russian natural gas exports have plummeted in half.
At far higher prices, giving Russia more money than they made before. That's what counts.
Right you are. The one existing gas pipeline to China, comes from a Rus gas field too far East from Europe. This gas was always going to go to China. And it terminates in Northern China where this natural gas cannot help the Chinese manufacturing regions of Guandong, Shenzhen, etc.
I doubt the Chinese have much of an internal natural gas distribution network via pipelines.
