"You can not place sanctions on two OPEC founder members and still blame OPEC for oil price volatility", he said in a statement to Reuters, referring to itself and Venezuela. The Brent benchmark dipped by $0.69 and was trading at $75.77-a 0.90% decrease on the day.
The Organization of the Petroleum Exporting Countries and some non-OPEC producers, led by Russian Federation, agreed to cut output in 2017 to reduce a supply overhang, which has led to a 60 percent spike in oil prices over the past year.
Oil slipped after Russian Federation was said to propose that OPEC and other producers in a global alliance reverse the supply cuts they've been making since early past year.

But the Paris-based IEA, echoing statements from oil producers as well as analyst comment in recent weeks, said there may be a change to the so-called Vienna agreement.
"Saudi Arabia and Russian Federation have already started to lift production", he said.
"While some members appear to be against the idea, we believe that we will see a gradual lifting of cuts", said Warren Patterson, a commodities strategist at ING Bank NV in Amsterdam.

Last week, the American Petroleum Institute (API) reported a build of 2.028 million barrels of crude oil. That move took US crude from about $50 a barrel in late 2016 to more than $70 in 2018. Russia's production was 11.1 million barrels a day in June, exceeding its quota, according to sources familiar with the matter.
"With rising production from USA shale adding to oil's woes and reviving oversupply concerns, further downside could be a possibility in the short to medium term", Otunuga said.
