Study on the Application of the "National Security Exception" Clause in the WTO Trade Rules

Abstract

For a long time, there have been differences and disputes on the restrictive application standards of the "national security exception" (NSE) clause in the WTO trade rules, and the clarification of the application of the "NSE" clause has become an urgent problem to be solved by the WTO dispute settlement body and the international economic law community. This article will start from China v. U.S. Steel and Aluminum Tariff Measures, combining the legislative concepts, doctrinal interpretations and judicial practice to clarify the limitations of the application of the "NSE" provisions.
