Dalian Commodity Exchange, China's largest derivatives market, may introduce energy, coking coal and live-hog futures contracts to spur trading volume. The bourse also aims to "be more than just agricultural or energy-oriented", President Liu Xingqiang said. "We're working on products that can be traded more easily as investments; that are more financial in nature. It will be a global exchange." The biggest contracts now include soybeans, soybean oil, palm oil and soybean meal. Futures trading in China, the third-largest economy, jumped 47 percent in the first half from a year ago, according to data compiled by the Futures Industry Association, as soybean and copper imports climbed to records. China's "growth in demand for raw materials still outstrips that of any other major country", said Nick Ronalds, executive director for FIA Asia. The "exchanges are likely to continue to grow faster than those of the rest of the world. In a few years, if it liberalizes its markets in time, they could be taking on the Western giants head-to-head".
