MOSCOW, April 30. /TASS/. The plan to restore oil production in June by 432,000 barrels daily remains the key option for the OPEC+ ministerial conference in May, a source in one of delegations told TASS.

"Probability is the highest that we will keep the current plan for June also," the source said. "Pressure from the US" is the only factor that can push OPEC+ member-states towards the revision of their plan, the source noted. Saudi Arabia and the UAE are the only countries actually having free production capacities, sources told TASS earlier.
