MOSCOW, Jan. 18 - The Finance Ministries of Russia and Ukraine in the next two months will prepare an agreement to fulfill the agreement signed by Russia and Ukraine in April 2010 on the extension of the presence of the Black Sea Fleet in Ukraine, Russian Finance Minister Alexei Kudrin said after meeting with his Ukrainian counterpart Fedir Yaroshenko.

"In the new agreement, we have to determine the procedures for calculating the discount for the price on gas as a source of payments for the lease of the [Black Sea Fleet] base after 2017," Kudrin said.
