BEIJING: China's state planner said it will probe coal and energy price index providers for publishing false and manipulated prices, spreading rumours and fabricating indexes, in another measure to cool prices of the fuel amid a power crunch.

The National Development and Reform Commission (NDRC) said in a statement on Monday that prices from some consultancies were completely deviating from supply/demand market fundamentals and seriously damaging public interest.
