The report released by the China Commodity Research Core showed that without exception, in 2011, China's top ten commodities with the highest external dependence all exceeded 40%, including soybeans, natural rubber and many other varieties whose external dependence exceeded 60%, indicating the high risk of the current dependence of China's economic growth on commodities. The data showed that in 2011, palm oil had the highest domestic commodity external dependence, reaching 100%, with the annual import volume reaching nearly 6 million tons. The well-known industry publication Oil World estimated that from October 2011 to September 2012, the demand for palm oil in the Chinese market would likely continue to increase by 750,000 tons, reaching 6.7 million tons. Meanwhile, in the ranking, the external dependence of soybeans, natural rubber, and sulfur resources all exceeded 70%, where the second-ranked soybean's external dependence reached 79%, and the external dependence of natural rubber, which has the attributes of agricultural products, industrial raw materials, and strategic materials, also reached 77%. In addition, the external dependence of crude oil and iron ore also reached 56.5% and 50.8% respectively, both exceeding the 50% dividing line. The total import data showed that energy products such as iron ore and crude oil, as well as steel, became the main force of imports. Among the total external dependence of the 20 products with higher external dependence, iron ore accounted for more than 50% of the total, and together with energy products such as crude oil, they almost contributed nearly 90% of the total external dependence of the 20 products, showing the huge "weight" of iron ore and energy products in China's economic development.
