BRUSSELS (ANA/M. Aroni) ? High Representative/Vice-President Federica Mogherini and Commissioner Johannes Hahn congratulated Prime Ministers Alexis Tsipras and Zoran Zaev for reaching agreement, and said it "contributes to the transformation of the entire region of South-East Europe."

The agreement, they said, provides a "window of opportunity that has been pushed wide open to accompany and consolidate the winds of peace and cooperation in the entire region."

Mogherini and Hahn added that they "now look forward to the Council endorsing our recommendation of 17 April to open accession negotiations with the former Yugoslav Republic of Macedonia in June." They said "this is not only merited, in recognition of the considerable reform results of the country, but it will contribute crucially to the full implementation of the agreement in the interest of both countries, of the region and of our Union as a whole."

The two officials added that the EU "encouraged and supported the negotiations from their very beginning" and pledged support for the next steps.
