China's comprehensive import price index for liquefied natural gas (LNG) dropped last week, according to Shanghai Petroleum and Natural Gas Exchange (SHPGX).

The LNG index, not including tax, came in at 2,655 yuan (about 378.6 U.S. dollars) per tonne in the week ending Feb. 23, down 11 percent from the previous week.

The index, jointly developed by a monitoring center under the General Administration of Customs and the SHPGX, was launched on Oct. 16, 2019 and is due on a weekly basis to offer a new pricing reference for importers.
