President Mesic described the relations between Croatia and Hungary as "continually good and friendly," adding that they could "serve as a model for good-neighbourly relations".
"We in particular discussed the two most important fields of cooperation, that is the energy sector and the construction of road and railway infrastructure," Mesic told reporters after the meeting.
Mesic added that Croatia was interested in intensifying the cooperation in tourism and environmental protection and that he accepted Solyom's invitation to join "an initiative of Green presidents" whose task is to warn about burning environmental issues such as greenhouse emissions and GMO.
Mesic accepted an invitation to attend a world scientific forum to be held in Budapest this autumn, which is to focus on the above issues.
The Hungarian president also stressed the importance of road infrastructure and added that Hungary was interested in being connected with the northern Croatian seaport of Rijeka as well as in the construction of the traffic corridor Vc from Hungary through eastern Croatia and Bosnia-Herzegovina to the south of Croatia.
As regards environmental protection issues, Solyom backed Croatia's decision to abandon plans for building dams on the Drava River.
Concerning Euro-Atlantic integration processes, Mesic thanked Solyom for Hungary's steady support to Croatia's efforts in this regard.
"Hungary supports without reservations Croatia's entry into the European Union and NATO. We have done our best to ensure that next year Croatia gets an invitation to join the North Atlantic alliance, and we did the same to help separate Croatia's EU accession negotiations from Turkey's," the Hungarian official said.
The two presidents agreed that the Croatian minority in Hungary and the Hungarian minority in Croatia enjoyed "a high level of protection".
In this context, Solyom expressed hope that the Hungarian community in Croatia's eastern region of Baranja would receive increasing assistance given that during the 1991-1995 war this region suffered much and the post-war reconstruction was at slower pace than in some other regions.
Solyom is scheduled to meet Prime Minister Ivo Sanader later in the day.
On Friday, he will hold talks with Parliament Speaker Vladimir Seks and visit Orahovica, Osijek and the Kopacki Rit nature park in eastern Croatia.
