This would happen regardless of any political issues. Russia has an unlimited supply of gas, China last year became the world’s largest energy importer, and they share a long border.

The Russian Jewish oligarchs have been working with the Israeli Jewish oligarchs since Israel discovered the Leviathan gas fields in the Mediterranean Sea back in 2011. Of course these businessmen will set up pipelines to a paying customer in China. It’s business.
