The Alpine Convention is an international agreement between all countries of the Alps (Germany, France, Italy, Liechtenstein, Monaco, Austria, Switzerland, and Slovenia) and the European Union for sustainable development and protection of the Alps. The Alpine Conference is the decision-making body of the Alpine Convention, comprising the ministers of the Alpine countries. The Alpine Conference meetings are usually held every two years in the member state that holds the presidency of the Convention (the presidency rotates every two years).
