Germany’s foreign minister urged Kosovo’s political parties Thursday to approve the border demarcation agreement with Montenegro to end their status as the only Western Balkan country without free travel rights in Schengen zone countries.

Minister Sigmar Gabriel was in Pristina on Thursday as part of his regional tour.

Opposition parties say Kosovo loses territory in the border agreement signed two years ago, and have blocked the governing coalition from ratifying the deal by continuously disrupting parliament.

Gabriel, who was in Serbia a day earlier, advised Kosovo and Serbia to continue their talks and “first of all to avoid provocations; second, to accept the reality; third, to care about how to make life easier for the people. This has to be the focus of the negotiations.”

Kosovo declared independence from Serbia in 2008.
