At present, Chinese mainland has Shanghai Futures Exchange (mainly engaged in futures of industrial products such as metals, energy and rubber), Dalian Commodity Exchange (engaged in futures of agricultural products such as soybeans and corn) and Zhengzhou Commodity Exchange (engaged in futures of agricultural products such as wheat, cotton and sugar).
This last one hasn't been decided yet, so there are only three above.
China Financial Futures Exchange (hereinafter referred to as CICC) will list financial futures products, and Shanghai and Shenzhen 300 stock index futures will take the lead in listing. There are more than 200 futures companies.
