This is the first book to focus on the theoretical and practical issues of export control. It combines the points of view of Japanese and French academics and practitioners, including personnel at several governmental institutions and private companies. Presenting the results of a collaboration between Japanese and French academics, it contributes to the development of a new debate on export control. Although export control has been discussed within the framework of international law in terms of peace and security, its scope has now been expanded to international economic law (i.e., WTO law and international investment law). This means that in order to discuss export control appropriately, the two areas of law have to be combined. At the same time, this topic is not only academic and theoretical but touches upon very real and practical aspects of trade, export, and foreign investment. When we tighten embargos and economic sanctions for anti-terrorism or anti-nuclearization purposes, we encounter more and more cases of conflict between security and the liberalization of economic relations in the world. For this reason, a wide range of collaborative work is needed in this area. This timely book addresses various aspects of the current export control debate.
