Montevideo Convention - Signatories

Signatories

The states that have signed this convention are limited to the Americas:

However, as a restatement of customary international law, the Montevideo Convention merely codified existing legal norms and its principles and therefore does not apply merely to the signatories, but to all subjects of international law as a whole.

The European Union, in the principal statement of its Badinter Committee, follows the Montevideo Convention in its definition of a state: by having a territory, a population, and a political authority. The committee also found that the existence of states was a question of fact, while the recognition by other states was purely declaratory and not a determinative factor of statehood.

Switzerland, although not a member of the European Union, adheres to the same principle, stating that "neither a political unit needs to be recognized to become a state, nor does a state have the obligation to recognize another one. At the same time, neither recognition is enough to create a state, nor does its absence abolish it."
