European diplomacy refers to the methods and practices used by countries in Europe to manage their relationships with one another and with the rest of the world. It involves negotiations, treaties, and discussions aimed at resolving conflicts, promoting trade, and fostering cooperation on issues like security and climate change. Key institutions, such as the European Union (EU) and the European Council, play significant roles in shaping diplomatic efforts. These organizations facilitate dialogue among member states and help coordinate policies on various matters, ensuring that European nations work together to address common challenges and enhance stability in the region.
