OIMAP has concluded cooperation agreements with four international organizations: the World Customs Organization (WCO), Interpol, UNESCO and the International Council of Museums (ICOM).

Each agreement specifies what the parties exchange, how they train together and who acts as point of contact. See also the overview of partners.

Indicative weight of each agreement in cooperation activity.

The World Customs Organization

The agreement with the WCO concerns the control of movements of cultural property at borders. OIMAP provides customs services with lists of flagged works, identification notices and Academy training. In return, customs transmit the seizures that feed the BIOP database.

This cooperation is at the heart of coordinated operations: twenty-three were carried out in 2024 with the national services concerned.

Interpol

The agreement with Interpol organizes the exchange of police information on thefts and trafficking networks. OIMAP alerts and international police notices complement each other: one specializes in cultural property, the other covers crime as a whole.

Joint exercises make it possible to test the alert chain, from the reporting of a theft to dissemination to the services concerned, within 24 hours for priority reports.

UNESCO

With UNESCO, cooperation rests on the 1970 Convention on illicit transfers of cultural property. The two organizations carry out awareness-raising actions, share their legal analyses and support States preparing a restitution request.

OIMAP contributes its operational expertise: certification, provenance documentation, mediation. UNESCO contributes its normative authority and its network of States Parties.

The International Council of Museums

The agreement with ICOM concerns collection ethics and the training of museum professionals. The two organizations jointly develop teaching materials and red lists of at-risk objects, published in the official languages.

It also facilitates contact with the network of partner museums, described on the Museums page.
