Which modern international framework echoes the “Concert of Europe” principle from the Congress of Vienna?

💡 Explanation:

The Concert of Europe was an informal system established after the Congress of Vienna (1815) where the Great Powers (Austria, Prussia, Russia, Great Britain, and later France) collectively managed European stability and vetoed action they opposed. This fundamental principle of a select group of major powers having unique authority and a veto over collective security and global governance is institutionally reflected in the permanent member structure (P5) and veto power of the UN Security Council.
