“Prevention”, “cooperation”, and “awareness raising” are the terms that one hears when it comes to preventing illicit trafficking in cultural property. The challenges are many: thefts in museums, public and private spaces, and archaeological sites are ongoing; conflicts ravaging the Middle East are leading to a surge in looting and trafficking; and circulation and sale of trafficked objects and frauds, also increasingly on the Internet, are sophisticated, linked to international organized crime, and hard to track.
