The OSCE Minsk group co-chairs will visit the region of the Nagorno Karabakh conflict in the middle of May. Armenian foreign minister Vardan Oskanian told journalists. He doubted they would make any new proposals on the conflict settlement. "In all probability, the mediators will exchange views with the leaderships of the countries," - the minister said. In his words, it is possible for concrete suggestions on the conflict settlement to be presented after that.
