Russian President Vladimir Putin left Beijing with no sign of a breakthrough on a natural gas pipeline project with the potential to reshape global energy flows and geopolitics.

Russia has been trying for years to reach a deal on the Power of Siberia 2 link that would more than double its current gas exports to China. Putin¡¯s state visit to the capital was expected to feature discussions as the Strait of Hormuz¡¯s de-facto closure cast doubt on the long-term reliability of seaborne liquefied natural gas.

¡°There is an understanding regarding all the key parameters for Power of Siberia 2,¡± Kremlin spokesman Dmitry Peskov told Russian media in Beijing. ¡°There are just some details left to be finalized,¡± he said, adding that the timeframe for the link has not been determined.
