Russia earns $11 billion more from oil this year
According to CCTV News, on December 6, local time, Russian President Vladimir Putin arrived in Abu Dhabi, the capital of the United Arab Emirates, and began a working visit to the United Arab Emirates. During his visit, Putin will focus on negotiating with the UAE on international and regional affairs such as energy cooperation, bilateral relations, and the Palestinian-Israeli conflict.
When meeting with visiting Russian President Vladimir Putin, UAE President Mohammed said that the UAE is Russia's largest trading partner in the Gulf region, and the two countries have jointly participated in a number of multilateral international cooperation framework mechanisms.
Putin said that relations between Russia and the United Arab Emirates have reached a high level, and cooperation between the two countries in the economic and industrial fields has made significant progress. Putin also said that he would discuss regional hotspot issues and the progress of the Ukraine crisis with the UAE.
According to Red Star News, since the outbreak of the Russia-Ukraine conflict, the "OPEC" mechanism in which Russia participates has been operating well, and the production reduction agreement has ensured the firmness of oil prices.
Prior to this, Western countries not only wanted to prevent Russia from obtaining excessive profits from oil exports, but also met the demand for oil from developed countries, so they set a ceiling price for Russian oil of US$60 per barrel. However, analysis by international organizations pointed out that Russia's actual average export price is about US$72 per barrel. Based on this, Russia's oil export revenue this year is estimated to be US$11 billion higher than the upper limit "allowed" by the West.
