He said Russia has received a proposal from Belarus to increase the tariff by 20%, but the size of the increase will still be discussed.
The Energy Ministry confirmed this information. However, a ministry spokesman said that the countries now have a special method for the calculation of oil transshipment tariffs.
"According to it, any change in the tariff for transshipment of Russian oil through Belarus must be economically rationalized. The issue will be decided in accordance with the existing method," he said.
