KIEV, Dec. 16 - Naftogaz Ukrayiny does not intend in the current winter to buy natural gas from Gazprom without signing an additional agreement to the contract for its sale and purchase, said Andriy Kobolev, head of the state holding.

"If the Russian colleagues do not accept the standard terms of the contract [do not sign the additional agreement that is traditional in recent years] by the end of winter, we are unlikely to buy gas from them," he said at a press conference in Kiev.
