Why does this matter? China gets more than 50% discount on LNG imports from Russia is a massive sign of Russian desperation and China putting the screws to them.
Russia isn’t doing this because they really like China. This shows they have no leverage or options at this point. The big picture of money coming in for Russia greatly affects their warfighting capability. This type of agreement is worth paying attention to.
They just follow the money. What’s interesting is during that VJ day parade, all the media showed Xi meeting Putin. Little of it showed Xi meeting with the Serbian (EU) President who was also there, or the Slovakian (EU and NATO) Prime Minister who was there as well. Representatives from the UK and USA were also there.
