"Not today, but I believe, within a week, no later," Yanovsky said.
The Energy Ministry has ordered companies to prepare contracts to 2037, to expand gas supplies to Poland and "improve the tariff", he added.
Russia and Poland agreed the text of the document on October 17. Gas will be supplied until 2022 while transit will be maintained until 2019, as in the previous contract.
The agreement also envisages a gradual increase in Russian gas supplies to Poland, from 9.7 bcm in 2010 to 11 bcm in 2012. EuRoPolGaz, a Russian-Polish joint venture operating the Polish stretch of the Yamal-Europe pipeline will set the transit tariff.
The Polish government has approved the agreement and is now waiting for EuRoPolGaz and Gaz-System gas operators to sign it.
