Both events are supported and organised by the Tourism Ministry and the Croatian National Tourist Board (HTZ) in cooperation with local partners in Rovinj and Istria, hotel companies and tourism boards. They all expect a large number of visitors in Rovinj as well as many other benefits for the national tourism industry in general, primarily in terms of promotion.
Officials of the Tourism Ministry said the 100th session of the UNWTO Executive Council would bring together more than 200 participants, headed by UNWTO Secretary-General Taleb Rifai.
Attending the conference will be Iran's vice-president, eight tourism ministers, and a large number of deputy tourism ministers, state secretaries and other tourism officials.
Croatia has been a member of the UNWTO since 1993. It was elected a member of the UNWTO Executive Council in 2013 and currently co-chairs the Council with Mozambique.
