(Yicai Global) Oct. 14 -- China's mainland stock markets opened lower this morning, dragged down by shares related to nonferrous metals after international gold prices plunged yesterday due to the International Monetary Fund's revised economic forecast.

The Shanghai Composite Index started 0.18 percent lower at 3,353.62. The Shenzhen Component Index was at 13,781.56, down 0.12 percent. The ChiNext Price Index, which tracks growth enterprises in Shenzhen, fell 0.25 percent to 2,777.89.

London's spot gold price slid over 1.6 percent to USD1,890.92 per ounce after the IMF lifted its global economic outlook, predicting gross domestic product to narrow by 4.4 percent instead of 5.2 percent.
