The Joint Ministerial Monitoring Committee, which includes Saudi Arabia and non-OPEC Russia, observes oil-market developments and can make a recommendation to the countries signed up to the deal, a group known as OPEC+.

A day before the JMMC, a technical panel called the JTC will hold its meeting, the sources said.
