Here's one: Each High Contracting Party undertakes to prevent the exportation, from a territory occupied by it during an armed conflict, of cultural property as defined in Article 1 of the Convention for the Protection of Cultural Property in the Event of Armed Conflict, signed at The Hague on 14 May 1954.
(Protocol para. 1)

See, also:

Resolution I

The Conference expresses the hope that the competent organs of the United Nations should decide, in the event of military action being taken in implementation of the Charter, to ensure application of the provisions of the Convention by the armed forces taking part in such action.

See, also Resolution II, hoping that each signatory will have qualified specialists on this issue in place for advisement.
