The European Commission said more time was needed for landlocked states that rely heavily on Russian oil delivered via pipelines to find alternate supplies.
Germany, Europe's biggest economy, is particularly reliant on Russia's gas, but has managed to cut Russia's share of its imports from 55% to 35% since the invasion, Economy Minister Robert Habeck said last month.
The urgency to ditch Russian energy ratcheted up in April when the country cut off supplies to Poland and Bulgaria, making good on President Vladimir Putin's earlier threat to suspend deliveries to "unfriendly" countries which refused to pay in rubles.Finnish state-owned gas firm Gasum — which has also refused to pay in rubles, unlike some of Europe's other energy companies — said on Wednesday that its Russian gas supplies could be cut off this weekend.
