Abstract: The Tokyo Convention establishes the principle of state of registration jurisdiction and the parallel jurisdiction system concerning international aviation crimes, and this system directly affirms the extraterritoriality of the international aviation crime jurisdiction, and avoids the difficulty due to the lack of bilateral extradition treaty, but there are some defects in it, especially the negative conflict of jurisdiction. In response to this problem, major countries concerned have raised their respective claims, and there are certain divergences between them. Combined with the practice of international community and the claims of different countries, the International Civil Aviation Organization suggests revision of the jurisdiction of related crimes in the Tokyo Convention, which has made corresponding reform to the jurisdiction on the basis of the original system, and contributes a lot to deal with the related crimes in the field of aviation. In this regard, China should transform the binding articles of the revised convention and fulfill its international obligations, so as to effectively maintain the security and order of international aviation.
