“It seems to me that most Russ to China gas exports are done via LNG ships.”
Not according to the most recent statistics I could find.
Russia exported 12.145 million mt of natural gas, comprising 4.61 million mt of LNG and 7.54 million mt of pipeline gas in 2021, according to China’s General Administration of Customs. The total volume rose 51% year on year, with LNG imports falling 9.8%, while pipeline gas imports rose 154%
Thanks for those statistics.
