Josipovic told the press after the talks that he was satisfied with the fact that Croatia's contribution to NATO operations was highly appreciated. "I am very satisfied that our allies highly appreciate our participation in operations, notably in Afghanistan," Josipovic said.

Rasmussen said he highly appreciated that Croatia had a leading role in the training of Afghan soldiers and police officers. Speaking about the situation in the region, Rasmussen said NATO insisted on its "open-door" policy.

Croatia is an example of a successful integration with NATO. Euro-Atlantic associations represent the best means for securing permanent peace and stability in the region. The recent arrest of Ratko Mladic sends a clear signal to the entire world that war crimes will be punished in the end. This is an important step towards the realisation of our ambition that all countries of the region are integrated with the EU and NATO, including Serbia, Rasmussen said.

The NATO secretary general said the situation in Bosnia and Herzegovina was worrying.

We expect political leaders to play a more constructive and responsible role so as to reach an agreement which will enable the functioning of state institutions. We entirely support Bosnia's aspirations to join NATO. We will continue to provide technical assistance for reforms necessary for joining the Membership Action Plan (MAP), but leaders must show political will to carry them out, Rasmussen said.

The talks also focused on the NATO-led operation in Libya. Rasmussen said NATO was determined to protect the civilians from the Libyan regime, adding that Muammar Gaddafi had to go.

Later today, Josipovic will deliver a keynote speech at the World Copyright Summit. On Wednesday he is expected to hold talks with European Council President Herman Van Rompuy.
