The G7 group of countries and its allies have officially approved a cap on the price of Russian oil.
In a joint statement, the G7 and Australia say the price cap will come into force on 5 December or “very soon thereafter”.
It comes after the European Union agreed on the price cap after persuading Poland to back it.
The plan, which stops countries paying more than $60 a barrel, needed the agreement of all EU states.
Poland announced its support on Friday after being reassured the cap will be kept at 5% lower than the market rate.
