Article 52 Relationship to other conventions and agreements

This Convention does not affect the rights and undertakings of Parties derived from international multilateral instruments concerning special matters.

The Parties to this Convention may conclude bilateral or multilateral agreements with one another on the matters dealt with in this Convention, for the purposes of supplementing or strengthening its provisions or facilitating the application of the principles embodied in it.

If two or more Parties have already concluded an agreement or treaty in respect of a subject which is dealt with in this Convention or otherwise have established their relations in respect of that subject, they shall be entitled to apply that agreement or treaty or to regulate these relations accordingly, in lieu of the Convention, if it facilitates international co-operation.

Parties which are members of the European Union shall, in their mutual relations, apply Community and European Union rules in so far as there are Community or European Union rules governing the particular subject concerned and applicable to the specific case, without prejudice to the object and purpose of the present Convention and without prejudice to its full application with other Parties.
