Russian Prime Minister Mikhail Kasyanov will start a two-day working visit to Ukraine and Moldavia tomorrow. A source in the governmental staff reported to journalists that the main topic of negotiations between the Russian top official and authorities of Ukraine and Moldavia will be gas problems. In particular, they will discuss the work of a gas pipeline that passes from Russia through the territories of Moldavia to Europe, issues on electrical industry and agricultural cooperation. In addition, they will discuss possibilities of an increase in traditional exports from Moldavia - wine, fruit and cognac. Kasyanov may also raise a question on the fate of Russian military warehouses that remained in Moldavia after the withdrawal of Russian troops.
