BEIJING, Aug. 4 (Xinhua) -- China will soon launch a new commodity futures contract as the country pushes for development of its commodity derivatives market.

Starting from Aug. 18, cotton yarn futures will be trading on the Zhengzhou Commodity Exchange, with preparation work for the launch already completed, said the China Securities Regulatory Commission in a statement Friday.

Trading tests will take place on Aug. 5 and 12.

Futures contracts obligate investors to buy or sell underlying assets at a predetermined price at a specified time, helping investors mitigate risks of price volatilities.

In an earlier note the CSRC said cotton yarn futures together with cotton futures, which are already traded, would help companies in the industry to hedge against and improve the management of risk.

Large and frequent fluctuations in cotton yarn prices have had a negative impact on related industries in the past few years, and the launch of the cotton yarn futures will be an answer to market demand, the CSRC said.

China has been developing its commodity derivatives market and plans to gradually open it up to foreign investors. Earlier in April, the country launched white sugar options, the second commodity options after soybean meal.
