Russia will halt its supply of natural gas to Finland on Saturday, the Finnish state-owned energy firm Gasum says.
Finland has been refusing to pay for its supplies in roubles. But it also follows an announcement that Finland will apply for NATO membership.
Finland imports most of its gas from Russia but gas accounts for less than a tenth of the country’s energy consumption.
Despite its invasion of Ukraine on 24 February, Russia continues to supply gas to many European countries.
After Western powers sanctioned Russia over the war, Russia said “unfriendly” countries must pay for gas using the Russian currency, a move the EU considers blackmail.
“It is highly regrettable that natural gas supplies under our supply contract will now be halted,” Gasum CEO Mika Wiljanen said in a statement.
“However, we have been carefully preparing for this situation and provided that there will be no disruptions in the gas transmission network, we will be able to supply all our customers with gas in the coming months,” he added.
Last Sunday, Russia also cut electricity supplies to Finland. It had threatened retaliation should Finland apply to join NATO.
