Abstract: Missile and Technology Control Regime is currently not a legally binding international regime. The regime's effectiveness is substantially ensured by unilateral conducts of those great powers such as the United States, particularly the latter's export control system. For purpose of sustaining the regime's effectiveness, it is necessary to correct the regime's drawbacks with respect to fairness and lawfulness, then to consolidate the regime's legitimacy. The future of the regime should be a transnational legal process of cooperation and interaction, which is based upon a wide acceptance by the international community of the objective and measures of the regime.
