In the exercise of its competences, each environment, and thus also Osijek-Baranja County, establishes a series of contacts and periodical or more durable cooperative relations with congenial or other in- and outland organizations or institutions.

Via these Web pages, our intention is to observe the more durable cooperative relations pertinent to the County's accession to certain domestic and international associations, i.e., to the establishment of bilateral or multilateral cooperation based upon the concluded agreements or similar documents.

On these Web pages, you will be able to find the data on County's membership in certain associations and established cooperation, i.e., the documents whereupon these relationships are based (agreements, statutes, decisions and other acts), the news pertinent to the activities conducted in this framework, as well as other data of importance to a certain cooperation aspect. These pages do not replace these associations' official Web sites but only provide the data on County's participation in the activities of their own. Provided that the organizations' Web pages whereto the cooperation or membership are related exist, their addresses will be also adduced.

Currently, Osijek-Baranja County has established cooperative relations, i.e., is a member of,

* Danube - Drava - Sava Euroregional Cooperation
* Republic of Croatia and Republic of Hungary's County-based CBC
* European Sustainable Cities and Towns Campaign
* Croatian Institute for Local Government
* Osijek-Baranja County Tourist Association
* Croatian Counties’ Association
