International conventions are important legal sources in civil aviation field, yet the conflicts between different versions of texts that are of the same effect have resulted in many troubles in understanding and applying of those conventions as well as in the communications between ICAO member states. Due to this situation, the project aims to edit and translate international conventions without the Chinese versions that lack official recognition and then submit them to be reviewed by relevant departments, and collect existing Chinese versions to correct inaccurate wordings and unify all expressions. Its final results will be applied to practical work as a series of books.
