TAIYUAN - China Taiyuan coal transaction price index stood at 140.03 points Monday, down 0.28 percent week on week.

The index, released by China Taiyuan Coal Transaction Center (CTCTC) based in Shanxi, a coal-rich province, reflects the coal price levels and changes in the main production areas of China. It is published every Monday.

Analysts said that the purchase demand of China's main power plants had decreased over the past week and the transaction of power coal in northern ports fell short of expectation, which caused coal enterprises in Shanxi to have higher stocks and coal prices to fall slightly.

With more than 10,000 registered coal traders, the CTCTC is the largest coal trading center in China.
