"Multi-Speed Europe" refers to the concept within the European Union (EU) where member states can progress at different rates in terms of integration and cooperation. This idea acknowledges that not all countries are at the same level of economic development or political alignment, allowing some nations to advance in specific areas while others may choose to opt out or move more slowly. This approach enables flexibility in addressing various challenges, such as the Eurozone crisis or migration issues, without requiring unanimous agreement from all member states. It allows for deeper integration among willing countries while respecting the diverse interests and capacities of others within the EU framework.
