We clearly want those countries to become members of both associations, which is important for the political stability and economic development of the region, Klaus said opening the first plenary session of a summit in Brno which gathered the presidents of 15 Central European states.
The participants in the 14th summit were discussing the situation in the region, bilateral relations and European unification.
Speaking about Kosovo, Klaus said he supported the international community's plan for Kosovo, but also the finding of a solution acceptable to all sides so that the future of the southern Serbian province could be stable.
Croatian President Stjepan Mesic said the long term solution to Kosovo's status was one of the key ones for the permanent stability of the region and that it was in the interest of all that it should be just and acceptable to both sides.
Different opinions could be heard at the plenary session about Kosovo, from Serbia, which maintains that it cannot give up its territory, to those maintaining that there should be an agreed solution in which no one must be defeated, Mesic told the Croatian press covering the summit.
He said the session discussed topics important for EU countries, accession candidates and those wishing to become candidates, including what the EU and NATO meant, and crisis spots in Europe, notably Kosovo.
On the fringes of the summit, Mesic is due to meet his Italian and Polish counterparts, Giorgio Napolitano and Lech Kaczynski.
