China's soaring demand for LNG is sparking industry hopes that a supply overhang causing a slump in prices will end sooner than initially anticipated.

China's imports of LNG in January rose 39.7% from a year earlier to 3.44 million tonnes, data from the General Administration of Customs showed on Feb. 23.

It was the second-highest monthly import level, behind a record 3.73 million tonnes set in December.

The steep growth rate in 2016 imports have propelled China past South Korea to become the world's second-biggest LNG importer, after Japan.

The LNG industry is banking on China's growing demand to end a global supply overhang triggered by a wave of new production, especially in Australia and the U.S. The glut has driven Asian spot LNG prices down by almost 70% since their 2014 peak to $6.40 per million British thermal units.

China's growing demand, much of it coming from import facilities called floating storage regasification units (FSRUs), means that supply and demand in the LNG market could come into balance by around 2021-2022, about a year earlier than previously expected, said Peter Coleman, the CEO of Australian oil and gas major Woodside Petroleum.

"It's growing very quickly," Coleman told analysts at a results briefing on Feb. 22.

Beyond China, producers hope that rising demand in South and Southeast Asia will also help soak up the wave of new production.

Royal Dutch Shell Plc (NYSE: RDS.A), the world's biggest LNG supplier, said this week that it estimates Southeast Asian LNG demand will rise above 50 million tonnes per annum (mtpa) by 2035, up from 10 mtpa currently.

"Most of the new import projects are being launched by floating (regasification) units," Steve Hill, Shell's executive vice president of gas and energy marketing and trading, told reporters at a briefing in Singapore.

He said the bulk of Southeast Asian import growth would come from Indonesia, which he said was suited for small-scale import projects as the country, spread across some 17,500 islands, is too large to be linked via natural gas pipelines.

In South Asia, Pakistan has soaring demand. The country started importing LNG in May 2015 via a FSRU at Port Qasim, and saw 2016 imports rise to 3.9 million tonnes, or about 28% higher than in 2015.
