TEHRAN June 13(Shana)--The price petrochemical plants should pay for feedstock and a long-term feedstock price formula will be finalized within the next ten days, deputy minister of petroleum Abbas Shari-Moqqadam said.

Speaking to Shana, he referred to a call announced for investment in Siraf refining project, adding a similar investment call will be announced for building Islamd Abad Gharb petrochemical complex, and if it is successfully carried out, the same method will be used for inviting investment in other petrochemical complexes in the further.

After a year of ups and downs, no formula has yet been finalized for setting the price of feedstock for petrochemical complexes.

Investment in petrochemical projects to a great extent depends on setting a long-term formula for the price of feedstock.

Fixing the price of feedstock under a long-term formula and in a completive way, creating necessary infrastructures by the government and putting in place stable regulations are thought to be the main factors for boosting investment in petrochemical sector.
