Abstract: The impact of GMOs on the environment and public health has been a heated issue which many scientists and international institutions take seriously. Because the existing technologies cannot lead to a precise understanding of the overall impact of GMOs on the environment， the international legislation of GMOs has been plodding along. Based on the early international legislation of GMOs and an analysis of the new developments of international legislation of GMOs， it is suggested that the legislation of GMOs should be closely related to the theories of decision making selected by the government and the learning-action principle should be followed in consideration of Chinas current situations.

Key words: GMO, environmental protection, international legislation
