The ministers of culture of Serbia, Bosnia and Herzegovina, Montenegro and Croatia signed Monday in Sarajevo a letter of intent on fostering cooperation among cultural institutions in the region, the Serbian Culture Ministry said.

The four countries will work together on drafting a document aimed at placing of stechaks - medieval standing tomb stones - on UNESCO's world heritage list, at UNESCO's recommendation.

The ministers met to discuss a plan of activities with defined commitments, deadlines and funding. They also made a commitment to exchange information relevant to the project.
