欧盟的国际制裁虽然以实践为目的,但作为制裁基础的欧盟基本法却一直存在范围不清、界限不明的问题。《里斯本条约》通过后,欧盟法对国际制裁法律基础的规定更加明晰,即通过明确欧盟机构在各领域采取行动的权限和程序,使得欧盟国际制裁的法律基础更加规范。但欧盟的改革也存在一些问题,如欧盟依据联合国安理会决议实施的制裁在实践中受到质疑,特别是在对成员国实施制裁的问题上,欧盟采取行动的法律基础依然欠缺。解决这些问题的关键是欧盟法应向更加一体化和类型化的方向发展。 Although the EU’s international sanctions aim at practice, the EU’s basic law, which is the basis for sanctions, has always had problems with unclear boundaries and unclear boundaries. After the “Treaty of Lisbon” was passed, the EU law further clarified the legal basis for international sanctions. That is, the legal basis for international sanctions in the EU was made more standard by clarifying the authority and procedures for EU agencies to take actions in various fields. However, there are some problems with the EU’s reform. For instance, sanctions imposed by the EU on the basis of UN Security Council resolutions have been questioned in practice. In particular, the legal basis for EU action is still lacking, especially in the enforcement of sanctions against member countries. The key to solving these problems is that the EU law should move toward a more integrated and typed approach.
