The online meeting will just be among OPEC members, believed to be scheduled for 1000 GMT on Thursday, ahead of the OPEC+ talks later in that day itself. It is said that the meeting will be for "internal matters" rather than about discussing output policy.
Thereafter, the JMMC meeting will take place at 1300 GMT before OPEC+ ministers will be meeting up at 1400 GMT for the full meeting. It looks like they are going to try to settle whatever rift that is going on, and that is helping oil prices push up today with WTI crude up 1% to $75.60 currently.
