Gas supplies from Russia to its western enclave Kaliningrad abruptly ended on Monday of this week and within 24 hours resumed.
Alexander Rolbinov, Deputy Chairman of the Government of the Kaliningrad Region, said that gas transit had been restored. He also emphasized that the region had switched to pipeline gas.
Supplies stopped at around noon GMT on Monday, without warning from Gazprom, said Amber Grid, which operates Lithuania's gas transmission system.
Gazprom has a transit agreement with the Lithuanian operator to pipe gas from the Belarus-Lithuania border to Kaliningrad, which is separated from the Russian mainland.
Home to the Russian Baltic Fleet and a deployment location for Russian nuclear-capable Iskander missiles, Kaliningrad is sandwiched between NATO members Lithuania and Poland.
Russian President Vladimir Putin launched an LNG FPSO (floating, production, storage, offloading) vessel in Kaliningrad in January 2019, hailing it as energy security against gas pipeline disruptions.
The ship, the Marshal Vasilevskiy, has been leased out as a tanker and is currently en route to China with an LNG cargo loaded in Cameroon, Refinitiv Eikon data show.
