This study considers that both development and implementation of EU external trade policy were strongly determined by the fact that this policy was part of the very process of economic integration. If a common trade policy is the first step of a common economic policy, it can only be a means to achieve long-term agreements. Due to this aspect, this paper considers that the Communitarian Commercial Policy (CCP) should not be understood or addressed as an end in itself but as one means and even one of the most important ways to ensure the accelerated development and concerted economic and monetary unification process in the EU. Moreover, this concept promoter, namely “European construction”, achieving CCP has symbolic value because it is thought that once done, it triggers “chain reactions” of integration’ developments and “irreversibility points”.
