"We have requested that NDFI resources could be tapped for completing petrochemical development projects with direct supervision by National Petrochemical Company," said Mohammad Hassan Peyvandi.
He said petrochemical projects of the country have taken the full brunt of the lack of financing in the sector.
He also complained about the lack of cooperation between domestic banks and NPC.
The official said Iran needs to dip into the NDFI so it will see its petrochemical sector flourish as planned.
He also added that the new political atmosphere following Iran's July nuclear deal with world powers has ushered in a promising era of foreign investments in the sector.
Iran has more than 60 major half-finished petrochemical projects which, once completed, will dramatically raise Iran's annual petrochemical output.
By completion of the projects, Iran is expected to become a regional heavyweight in production of petrochemicals.
