Are there Differences between Chinese and American Rules Governing Air Defense Identification Zones (ADIZ)?

Abstract: American rules regarding air defense identification zones (ADIZs) have major implications for other countries, and to a certain extent represent the foundation for international norms in this area. There is no substantial different between U.S. and Chinese ADIZ rules, implying that China’s rules conform to international norms. In practice, American rules purposely blur the distinction between civilian and military aircraft, America not applying the rules to military aircraft. Its purpose in doing so is to support its traditional point of view that military aircraft enjoy the right to “freedom of navigation of the high seas,” enabling them to act freely in the ADIZs and exclusive economic zones of other countries. At present, no international law or convention restricts the rules of states regarding ADIZs, particularly when it comes to military aircraft. Just the same, international laws provide no clear security guarantee for coastal states. The U.S. and China should take full advantage of available platforms for the negotiation of international maritime security issues to enhance cooperation around and strengthen governance over ADIZs.
