Exactly.. Chyna has a paramount interest in cutting ties between Europe and Russia and they are using US as their bulldog.. The benefits would be two-fold:

• If EU stops buying gas and oil from Russia, they would start getting more expensive supplies from Middle East (Saudi Arabia, Qatar). That renders them even less competitive against Chyna.
• Russians haven been stripped of their main customer would have to turn to.. who else, Chyna.. Chyna would easily pay connections from Russia towards south and negotiate 8-10% better prices than EU currently have, resulting in 12-14% savings on energy compared to what they have today. That would render them practically unbeatable in terms of competitiveness vs. EU and US.

Putin and Trump have to work on this together.. But I fail to see how the NS2 would be a negative thing here as it only ties EU and Russia more together and pretty much eliminates the Chynese option.
