Poland's government has approved a gas agreement with Russia, local media reported on Thursday, citing a government spokesman.

The agreement clears an intergovernmental accord on Russian gas supplies to Poland, which was drawn up in December, according to the Polish news agency PAP.

On Jan. 27, Poland's PGNiG Oil and Gas Company and Russia's Gazprom Export signed an agreement on increasing Russian gas supplies to Poland to 10.2 billion cubic meters per year and extending the current agreement until Dec. 31, 2037.

The agreement extends the contract for gas transit through Poland via the Yamal pipeline from 2019 until 2045 on current terms.

The agreement was accepted by the PGNiG managing and supervisory board, the company said in a statement.

Russian gas has been flowing to Poland since the beginning of the year as if the agreement with Gazprom had been signed, otherwise Poland's storage facilities would have been empty, PGNiG Deputy CEO Miroslaw Dobrut said.

At present PGNiG's storage facilities are filled in over 30 percent, including mandatory reserves, Dobrut added.
