Cassava production is a new industry of which advantageous characteristic are good adaptability and high biological yield etc. Chinese cassava industry is confronted with tremendous opportunity and challenge after China joined WTO and Association of South-East Asian Nations (ASEAN). According to the investigation and research, the harvest area, yield, production, imports and exports trade of cassava were rapidly increased in the world since 5 years ago, and China imported the most cassava chip and tapioca in the world because of the domestic cassava manufacture demand exceeds supply. More over, new replaceable energy will be imperative under the situation that petrochemical energy resources are short in china. At present, cassava tapioca and auto-alcohol are better quality and economic efficiency than maize and sugarcane raw material. So, cassava commercialization has accelerated social and economical development in some South-China area now. At the same time，the problems of weak scientific research and extension, few adopted new cassava variety and technology, lack of industrial raw material, and behind technology of intensive processing and pollution-control etc. are slowing down the development of the commercialization of cassava. Naturally, the developing countermeasure of Chinese cassava commercialization will be getting more support from government, policy and finance, strengthening cassava research in breeding, high-yield physiology and biochemistry, intensive processing and pollution-control, enlarging cultivating area and spreading improved variety and technology etc.
