Prime Minister Boyko Borissov said on Sunday that steps were needed to continue the EU-Turkey agreement to stem the migrant flow.
He returned from a visit to Germany late on Saturday.
The Bulgarian Prime Minister had a brief one-to-one meeting with German Chancellor Angela Merkel. The talks took place within a meeting which also included the prime ministers of Croatia and Slovenia, Tihomir Oreskovic and Miro Cerar, and Austria's chancellor Christian Kern, which in turn is part of a series of working consultations Merkel is holding about the European Union's future prior to the EU summit meeting in Bratislava on September 16. The talks, whose main topic was the migration crisis, were closed to the media.
In a Facebook post prior to his meeting with Merkel, Borissov said that he will defend the Bulgarian stand according to which a common European solution is needed, along with genuine solidarity among the countries in Europe. Borissov was also set to familiarize his counterparts with the issues he discussed during meetings in Istanbul on Friday with the Prime Minister and the President of Turkey.
