U.S. President Trump said Wednesday he held talks with Russian President Vladimir Putin and Saudi Crown Prince Mohammed bin Salman, adding that he believes the two countries would make an agreement to end their price war in "a few days."
"I have confidence in both that they'll be able to work it out," Trump said at a White House briefing.
During the OPEC+ conference in Vienna, Austria on March 6, Saudi Arabia and Russia failed to make deeper cuts into the group's oil production levels in order to mitigate the adverse impact of coronavirus on weakening global oil demand.
