Problem setting. In spite of the presence of numerous conventions, treaties and organizations in the world today, the issue of security is still a very acute issue for the world community. There are many reasons for this: the presence of nuclear powers, serious disputes between countries that are justly considered world leaders, the existence of numerous local conflicts and wars of a more global nature across the globe. These and other factors are pushing states around the world to allocate budget funds to ensure effective security policies. Given today’s realities, one can trace the tendency of several countries to pool their own efforts and resources to pursue a common security policy. The European Union is one of the clearest examples of this behavior. This intergovernmental organization is committed to maintaining peace, diplomacy, trade and development around the world. The EU also promotes cooperation with neighboring countries through the European Neighborhood Policy.

Article’s main body. The article examines the emergence and development of the European Union’s security policy from the date of the Brussels Covenant to the present. Particular attention is paid to the role of the European Union’s institutional mechanism in the exercise of its powers to ensure the defense and foreign policy cooperation of the Member States. A study of the officially adopted five-year global foreign and security policy of the EU is being done to improve stability in Europe and beyond, analyzing EU conflict resolution and crisis management activities.
Conclusions and prospect of development. In view of the above, it can be concluded that the EU’s foreign and security policy institutional framework is an extensive system in which all the constituencies are endowed with a certain range of general and specific powers and are called upon to cooperate with one another to achieve a common goal. It cannot be said that such close cooperation puts pressure on Member States. Yes, a Member State has the right to refrain from voting for any decision that requires unanimity and such abstention will not prevent the above decision being taken. In this case, the mechanism of so-called “constructive retention” is triggered: the abstaining country is not obliged to comply with the decision, however, accepts the fact that it is binding on other Member States and takes this into account when concluding treaties, which should not contradict the said decision.
