International Day of Multilateralism and Diplomacy for Peace

In the event of a threat to the peace, multilateralism ensures the collective response of States. The principle of collective security is based on the multilateral approach. If one State is attacked, the others commit themselves to react. Multilateralism is also crucial for conflict prevention and resolution.

The genesis of modern multilateralism dates back to the 19th century. The Concert of Europe that emerged from the Vienna Congress in 1815 is considered a major step in its development.

Multilateralism is when at least three governments participate in a particular issue or to try to solve a problem. Multilateralism is an example of cooperation among world governments and used in contrast with unilateralism. Unilateralism is when a state acts without regard to the support or interests of other states.

In today's world marked by major geopolitical and economic power shifts, multilateralism is still the most effective means to govern global relations in a way that benefits all.
