TOKYO -- On Feb. 19, a Russian icebreaker that transports liquefied natural gas arrived at Sabetta, an LNG loading port in the far north of Siberia. The ship had sailed through the ice-covered Arctic Ocean on its way to and back from China's Jiangsu Province.
The journey is noteworthy because the Arctic Sea route that the ship took is usually only navigable from July to November, when the sea ice is thin.
