Nakon dugih odlaganja, u okviru projekta je poduzet veliki korak u julu prošle godine, kad je pet država-učesnica -- Austrija, Bugarska, Mađarska, Rumunija i Turska -- potpisalo međuvladin sporazum u Ankari.
After long delays, the project took a major step forward in July of last year, when the five participating states -- Austria, Bulgaria, Hungary, Romania and Turkey -- signed an intergovernmental agreement in Ankara.
