This article reviews the evolution of Chinese law on food safety and the concerned system defined by the Food Safety Law (2009) and other related laws. Although being improved by this law, in comparison with the Food Hygiene Law (1995), food safety still remains severe today. In analysing the food safety problems in China, it is found that the issues, such as tension between security and safety, problems in agricultural products, difficulties in administration and supervision etc., cannot be solved by this law in the near future.
