Abstract: In order to prevent and punish the illegal acts threatening the safety of international civil aviation, the international community has always been committed to the legislation development of aviation security, which culminates in the widespread adoption of International Aviation Security Conventions by various nations. The Chinese domestic laws do not have clear rules regarding the application and transposition of International Aviation Security Conventions, which cause many problems in both theory and practice. By highlighting the interface and interconnection between the domestic law and international law, we should clarify the legal force of applying International Aviation Security Conventions in China, and perfect the domestic legislation so as to better fulfill our international obligation, crack down on international civil aviation crimes and safeguard the order of international community.
