Frka-Petesic, who currently serves as the Prime Minister's Chief of Staff, was presented with the decoration by Moroccan Ambassador Nour el Houda Marrakchi on Tuesday.
The decoration was awarded by King Mohammed VI.
The ceremony was attended by the mufti of Zagreb, the Croatian parliament speaker's chief of staff, the assistant foreign minister for political affairs, former Croatian diplomats who had been posted in Morocco, and other prominent political and cultural figures.
Addressing the ceremony, Frka-Petesic said that the decoration was a mark of friendship and long-standing relations between the two countries going back to the 18th century.
He expressed hope that a high-level visit would be made soon in order to conclude an agreement on long-term and comprehensive partnership, which is expected to provide fresh impetus to relations between Morocco and Croatia.
