Abstract: The Beijing Convention defines acts of unlawful interference with civil aviation, such as using aircraft as weapons and transporting dangerous substances, as crimes. And it has added three kinds of jurisdiction and absorbed the useful provisions from other United Nations anti-terrorism conventions, thus updating the international aviation security convention system. At the same time, it has promoted the development of international aviation security convention system by establishing new criminal acts, integrating and standardizing the provisions of common law system and civil law system, and properly handling the relationship between the conventions. The Standing Committee of the National People’s Congress has reviewed and ratified the Convention, which will soon come into force in China. The ratification of this convention is of great significance to further guarantee the security of air transport and safeguard the safety of the lives and property of passengers.
