KIEV, March 29 – Gas contracts are so favorable for Russia that Moscow demands from Kiev the creation of a union or Kiev's joining the Customs Union in exchange for a review of these contracts, said former President Viktor Yushchenko.

"They [gas contracts] are so favorable for the Russian side that for their review … the creation of a consortium to manage the Ukrainian gas transportations system or access of Gazprom to the domestic market is not enough. Currently the Russian side in fact demands the creation of a union [in exchange] for the cut in prices for gas, or at least, Ukraine's joining the Customs Union with Russia," the press service of the Our Ukraine party cited Yushchenko as saying.
