He was speaking to the press at the 35th World Travel Market, taking place on November 3-6, after talking with Croatian Tourism Minister Darko Lorencin.
Lundgren said Dubrovnik was a strategic destination for TUI to which it would pay more and more attention because it was an important Croatian, regional and European destination. He said Split also had big potential for holiday, cruise and other passengers.
TUI sees potential also in the Istria and Kvarner coastal regions as well as in continental Croatia, he added.
The increase in TUI's turnover is being linked to its inclusion in the Karisma Hoteli Adriatic company, which has sent a letter of intent for Croatia's Kupari tourism project and is in the process of becoming a strategic investor in the Zivogosce Hoteli company in Makarska Riviera.
Minister Lorencin said the government would again discuss the Kupari project because parliament should provide its consent for a concession.
He said TUI told him Croatia was in the focus of its interest at the moment, that it planned to invest in marketing and other things, and that Croatia, through joint advertising, would support TUI and other British tour operators with good programmes, notably for the shoulder seasons.
