Do tell?
Russia will find markets at double the price, quadruple the profits, for all the gas they care to export. Do you really believe the West can just take a huge percentage of North American gas off the market and no one will make the effort to to access Russian gas? At a discount to boot. You’re flat wrong. From sanctions on, I’ve been right. It’s a boondoggle for Putin and Xi, a financial catastrophe for the consumers of energy.

China is not buying significantly more gas - instead the agreement is that the hard up Russians will now accept Chinese monopoly money, instead of hard currencies for what they had been selling anyway.
The gas that had been going to Europe cannot be physically transported to other customers. There are no new pipelines heading that way. The existing one (Power of Siberia) can operate at peak, but that is all. That pipeline is from different gas fields than the Yamal fields that service Europe. There is no slack LNG terminal capacity to export that (formerly) European product. That is why the European bound product is now just being burnt off in flares that are visible from space with the naked eye.
This new agreement is a benefit to China, because they can and do print that Chinese funny money like drunken sailors. Now they don’t have to pay some of their gas bill with real money any more.
At this rate, they will probably own Gazprom in a couple of years, for a penny on the dollar.
