"On January 1, 2025, at 8:00 Moscow time, the validity period of documents signed on December 30, 2019, ended: the agreement between Gazprom and Naftogaz of Ukraine on the transportation of Russian gas through the Ukrainian territory, and the cooperation agreement between the operators of Russia's and Ukraine's gas transmission systems – Gazprom and Operator of the Ukrainian Gas Transmission System," Gazprom said on Telegram.
The company also said it had been deprived of an ability to supply gas to Ukraine due to the "repeated and explicit refusal of the Ukrainian party to extend these agreements."
"From 8:00 Moscow time the Russian gas supply for its transportation through the territory of Ukraine is not carried out," the company said.
