Greek PM Alexis Tsipras intervened from Thessaly following the bleak projections by the IMF on Greece’s primary surplus.

"Our common future in the Balkans cannot be built on nationalism, as has unfortunately happened in the past, or on third party plans for our region; it can be built on the great potential of our peoples, respect for international law and a common European vision for our region," Prime Minister Alexis Tsipras said in his joint statements with Bulgaria's Prime Minister Boyko Borissov, Romania's Prime Minister Mihai Tudose and Serbian President Aleksandar Vucic, after the conclusion of the first Quadrilateral Summit Greece-Bulgaria-Romania-Serbia, held in Varna.

Prime Minister Alexis Tsipras accepted the invitation of President Donald Trump and will visit the White House in the second half of October.
