Doesn't PipeChina also cover oil pipelines?China has unbundled its pipeline network from the gas majors. They did this some 2 years ago.
They could just do the same to the oil pipeline network if they did not do this already.
Russia has a fully native gas pipeline industry. This includes the pipes themselves, the steel used to make them, the gas turbines to pump the gas, etc.
Also Chinese companies might not have all the leading edge oil processing equipment but they clearly have enough of it or the Iran trade deal would never have been possible in the first place. Iran has been sanctioned to hell and back for like 50 years.
Is there a max capacity set for Power of Siberia II, or are they just gonna up it now since it hasn't been built yet?
