Compared with other domestic legal branches，the most important character of aviation law is its internationality，and foreign-related aviation legislation is an important part of domestic aviation legislation. At the international level，China has ratified and acceded to most of the international aviation conventions，and the ratification of the newly created aviation conventions has been in progress. At the domestic level，China has positively fulfilled its international obligations under international aviation conventions. In China，the main concepts，basic principles，rules and systems under aviation conventions have been transformed into domestic law through different approaches. In terms of international civil air transport，China has concluded bilateral air transport agreements with most countries and regions in the world，and also established a relatively perfect legal system for the management of foreign airlines. To promote overall law-based governance，we should promote both domestic and foreign-related rule of law at the same time. We should also keep to improve legislations and administrations which related to foreign airlines.
