Iran on Friday asserted its right to construct nuclear power plants saying these would be used only to meet domestic energy requirements.
"There is no reason for us to yield to illogical demands made and double standards applied by certain powers," Foreign Minister Manocheher Mottaki said in an apparent reference to the US.
Speaking at a seminar at the Indian Council for World Affairs in New Delhi, he said Iran had been closely co-operating with the IAEA and its inspection teams.
On the Middle East policy pursued by the US, Mottaki said "it is perhaps better for Americans not to interfere in decision-making process of other countries."
He called for regional economic integration among Asian nations and pointed to the need for more infrastructure projects, monetary and financial cooperation, and increasing trade and investment among countries.
Mottaki said the countries needed to cooperate in the field of energy for regional integration and welcomed investment from Indian firms in Iranian oil and gas sectors.
He hoped the LNG pipeline between India and Iran would transform political and economic relations between the two countries and improve ties between New Delhi and Islamabad as well.
He fondly remembered his days as a student in Bangalore and said he had great respect and admiration for Indian culture.
