Abstract: With more and more activities in the outer space, the space environment is deteriorating, and there are deficiencies in both international and internal space law. Based on the process of space debris removing, this paper puts forward legal restraints China should abide by as the main responsibility in the removing and legal protection other countries should seek as behavioral agent causing damage to China's satellites. The paper also suggests constructing legal mechanism on the research and test process about removing debris satellites, such as risk evaluation, admission register, scout warning, response mechanism, and compensation system of punishment. Finally the paper suggests speeding up the development of the national law, making use of international treaties and strengthening national space debris mitigation criterion and legal mechanism.
