Answering the UNIAN correspondent’s question on Monday on what policy the Bulgarian presidency will continue with regard to Russia sanctions, given that the country’s president earlier spoke about lifting economic sanctions against Russia, Tzantchev said.

"We’ll stick to the five principles of relations with Russia approved by the Council in March 2016. Full implementation of the Minsk agreements by all sides in the conflict in eastern Ukraine is an important condition for the change in EU relations with Russia. At present, this condition has not been fulfilled," he said.

The ambassador stressed that the EU "insists that Russia fully respect international law."
