Iranian Oil Minister Bijan Zanganeh said on Sunday that the country was not ready to freeze its oil output until output of 4.0 million barrels a day was reached.

"They should leave us alone as long as Iran's crude oil has not reached 4 million. We will accompany them afterwards," he said.

Zanganeh noted that $70 a barrel would be a suitable oil price.

He pointed out that Iran's oil exports will increase to 2 million barrels a day this month from 1.75 million barrels a day a month earlier.

Iranian oil minister will meet with Russian Energy Minister Alexander Novak on Monday.
