China News Client Beijing March 9th (Zhang Xu) Brent crude oil futures gapped sharply and opened 25% lower on Monday, once falling more than 31% to 32.14 US dollars / barrel. According to Bloomberg, Saudi Arabia sharply reduced crude oil prices sold to foreign markets in Europe, the Far East and the United States on Saturday, with the largest discount in more than 20 years to attract foreign refiners to buy Saudi crude. The market generally believes that this is after Saudi Arabia's refusal to reduce production at the OPEC + policy meeting on March 6th. Saudi Arabia, the main OPEC country, took the initiative to start a crude oil price war.
