BEIJING, Jan. 25 (Xinhua) -- China's benchmark power coal price went down slightly during the past week as stable supply eased panic buying.

The Bohai-Rim Steam-Coal Price Index, a gauge of coal prices in northern China's major ports published weekly, slipped 0.17 percent from a week ago to 577 yuan (around 90 U.S. dollars) per tonne, according to Qinhuangdao Ocean Shipping Coal Trading Market Co. Ltd.

The index was 2 percent lower than the same period last year.

The coal price had been rising since the end of November due to seasonal demand until government policies to ensure supply reined in the gaining streak. Coal stock at Qinhuangdao port has remained above 7 million tonnes for 12 straight days.

The approaching Spring Festival holiday has also curbed coal deals by factories that are scheduled to suspend production, analysts said.

China is in the middle of capacity cuts in coal and steel sectors. Last year's annual targets to slash steel capacity by around 50 million tonnes and coal by at least 150 million tonnes were fulfilled in August and October, respectively.
