Russia stopped the natural gas delivery to Finland's energy firm Gasum due to a lack of payments, Gazprom said on Saturday.
According to a written statement by the firm, Finland had to make payments in rubles as of April for the natural gas delivery, Gazprom said and added that deliveries to Gasum and Finland have been completely stopped on Saturday as the payments have not been made.
Some 70% of the natural gas consumption of Finland was met by Gazprom last year.
The Finnish firm said on Friday that the gas flow will stop on Saturday but it is ready for this situation.
Another Russian energy firm, RAO, also stopped exporting electricity to Finland due to the same reason last week.
