Saudi authorities have stated it was a consensus among OPEC+ member states.

President Joe Biden pledged on Tuesday "there will be consequences" for US relations with Saudi Arabia after OPEC+ announced last week that it would cut oil production over US objections.

The OPEC+ organisation's decision this week to cut oil production despite stiff US opposition has further strained already tense relations between President Joe Biden's White House and Saudi Arabia's royal family, once one of Washington's staunchest Middle East allies, according to interviews with about a dozen government officials and experts in Washington and the Gulf.

OPEC+ looks set for deep cuts to its oil output targets when it meets on Wednesday, curbing supply in an already tight market despite pressure from the United States and others to pump more.
