The price of oil rose on Monday after the G7 group of nations agreed to cap the price of Russian oil.
In morning trade in Asia, it was more than 1% higher than before.
The move raises Western pressure on Russia over the invasion of Ukrainian.
The oil producers' group Opec+ agreed to stick to its policy to reduce production.
The Opec+ decision to keep the quota is an implicit support to the oil market.

The G7 and Australia said in a joint statement last week that the cap on Russian oil would come into force on Monday.
They said the measure was intended to prevent Russia from making money from the war.
The price cap was put in place by the G7 in order to prevent Moscow from making money from oil exports.
Only Russian oil purchased for less than $60 a barrel will be allowed to be shipped.
Many major shipping and insurance companies are located within the G7, making it hard for Moscow to sell its oil at a higher price.
The G7 is an organisation of the world's seven largest so-called "advanced" economies. Canada, France, Germany, Italy, Japan, the UK and the US are included.
The price of oil and gas have gone up on fears of a supply shortage.

Ukrainian President Volodymyr Zelensky said the cap wasn't serious enough to hurt the Russian economy.
Russia threatened to stop exporting oil to countries that adopted the price cap.
The EU ban on Russian crude oil imports will take effect on Monday.
Russia's move to sell its oil to other markets such as India and China, which are currently the largest buyers of Russian crude oil, will make up for the impact of the measures.
