"The claim by the IEA that Iran has fulfilled only 5% of its OPEC undertaking for output cut is not true," Khatibi told FNA.
Noting that Iran presents true information and data on its produced oil to OPEC on a monthly basis, he reiterated that the information released in different media is contradictory, and that news outlets have a rough, and not a precise, estimate of Iran's production level.
The Paris-based IEA estimated in a report recently that OPEC completed 62% of its promised oil production cut in September, down from 66% in August.
Angola hasn't cut any and Iran made only 5% of its allotted reduction, the Organization alleged.
Also, Saudi Arabia, the UAE and Kuwait had the highest compliance rates in September, completing 99, 98 and 96% of their reductions, respectively.
