The LNG spot market will continue yielding high rates due to a sustained demand in China for clean power and limited supply, said Cosco Shipping Energy Transportation.

The LNG transportation business entered "a period of rapid growth" in the first half of the year, Cosco said in a statement to the Shanghai Stock Exchange.

The Chinese state owner is betting on local demand to keep rising due to the "firm implementation of the coal to gas policy," resulting in high spot charter rates till 2020 due to short supply.
