This was reported by Ukrainian temporary charge d`affaires in Russia Leonid Osavaluk after negotiations over Azov and Black Seas demarcation. Ukrainian side has expected suggestions on state frontier in Azov Sea from Russian representatives. "Unfortunately we got no suggestions but came to agreement that Russian side would introduce them in nearest future", - said Osavluk. The position of sides on Kerchensky channel has remained unchangeable - Ukraine insists on recognition of present frontier line, which existed during Soviet period, Russian side declares the absence of such frontier. The issues of Black Sea demarcation will be solved during next stage of negotiations. On session of expert groups for demarcation of land frontier sides have agreed to hold session of combined demarcation commission. "There is a serious progress in demarcation issues and we will realize our plans in nearest future", - said Ukrainian diplomat.
