The statement was signed at Brijuni Isles in the northern Adriatic on Friday at the third meeting of commissions in charge of the implementation of the charter.
The statement says the four countries will develop cooperation and continue to underline initiatives and projects which strengthen Membership Action plans, and to create conditions to step up participation in NATO operations.
Miomir Zuzul of Croatia, Ilinka Mitreva of Macedonia, and Kastriot Islami of Albania voiced readiness to cooperate in order to integrate with NATO faster.
Zuzul told the press the U.S.-Adriatic Charter had brought the three countries closer to NATO membership, and that admission was expected to occur soon.
He said cooperation and partnership with the United States was of outstanding importance for Croatia, Macedonia and Albania, and that initiatives such as the charter contributed to the stabilisation of Southeast Europe.
Zuzul said the Charter represented a model for other countries undergoing integration processes, and announced that the foreign ministers of Serbia and Montenegro and Bosnia-Herzegovina, Vuk Draskovic and Mladen Ivanic, as well as officials of seven NATO member countries, would arrive on Brijuni tomorrow, which he added would give Croatia, Macedonia and Albania support for NATO membership from the wider neighbourhood.
Macedonian Minister Mitreva said this kind of cooperation contributed to the security, stability and prosperity of Southeast Europe on the countries' road to the EU and NATO.
Her Albanian counterpart Islami said the Brijuni meeting was historic in the efforts of Croatia, Macedonia and Albania to integrate with NATO.
Assistant State Secretary Jones said her country would continue to support the three countries, which she added were ready for NATO membership.
