BRUSSELS, Dec 5 (Reuters) - The Group of Seven price cap on Russian seaborne oil came into force on Monday as the West tries to limit Moscow's ability to finance its war in Ukraine, but Russia has said it will not abide by the measure even if it has to cut production.
The price cap, to be enforced by the G7 nations, the European Union and Australia, comes on top of the EU's embargo on imports of Russian crude by sea and similar pledges by the United States, Canada, Japan and Britain.
It allows Russian oil to be shipped to third-party countries using G7 and EU tankers, insurance companies and credit institutions, only if the cargo is bought at or below the price cap.
As the world's key shipping and insurance firms are based in G7 countries, the cap could make it difficult for Moscow to sell its oil for a higher price.
Russia, which is the world's second-largest oil exporter, said on Sunday it would not accept the cap and would not sell oil that is subject to it, even if it has to cut production.
Selling oil and gas to Europe has been one of the main sources of Russian foreign currency earnings since Soviet geologists found oil and gas in the swamps of Siberia in the decades after World War Two.
A source who asked not to be identified due to the sensitivity of the situation told Reuters that a decree was being prepared to prohibit Russian companies and traders from interacting with countries and companies guided by the cap.
In essence, such a decree would ban the export of oil and petroleum products to countries and companies that apply it.
Still, with the price cap set at $60 per barrel, not much below the $67 level where it closed on Friday , the EU and G7 countries expect Russia will still have an incentive to continue selling oil at that price, while accepting smaller profits.
China's foreign ministry said on Monday that Beijing would continue its energy cooperation with Russia on the basis of respect and mutual benefit, following the EU's agreement of the price cap, Russia’s RIA news agency reported.
The level of the cap is to be reviewed by the EU and the G7 every two months, with the first such review in mid-January.
"This review should take into account... the effectiveness of the measure, its implementation, international adherence and alignment, the potential impact on coalition members and partners, and market developments," the European Commission said in a statement.
The cap on crude will be followed by a similar measure affecting Russian petroleum products that will come into force on Feb. 5, though the level of that cap has not yet been determined.
