I understand that Russians LNG can’t be sold profitably to anyone other than Europe. It would have to be liquidfied to ship to China or India and Russia doesn’t have that capability.
The pipeline to Europe is their only means of shipping that gas.
85% of Russia’s gas exports last year went to the EU (including Turkey) - overwhelmingly via fixed pipelines.
Turkey is likely going to keep running their Turkstream pipeline from Russia, but most of the rest (well over half of last year’s gas export volume) will have no physical way to get to market, as Europeans replace it.
