German Chancellor Angela Merkel said the dark clouds lean over Belgrade-Pristina dialogue after Kosovo introduced tariffs on the Serbian goods, Tanjug news agency reports. Talking to news correspondents in Berlin, Merkel emphasized that Germany has a major interest for European integration “of Serbia and Kosovo” there is a progress on that way, but as she underlined, it is necessary to restore the dialogue between Belgrade and Pristina. Tariffs lead to regression, and not to the progress, Merkel said, recalling that she spoke about that with Belgrade and Pristina leaders at the meeting in Berlin. “We must see now how to restore the dialogue. I have spoken with Aleksandar Vucic, Hashim Thaci, Ramush Haradinaj. There is yet no progress on this issue. We offered a meeting in Paris and it is necessary to work on that,” German Chancellor said, according to B92.
