India has rebuffed a call by the United States for it to ask Iran to suspend its uranium enrichment programme.
The foreign ministry said neither India nor Iran needed external guidance on how to conduct bilateral relations.
It said relations between the two spanned centuries, and they were capable of handling them with due care.
Earlier, a senior US official said Washington would welcome India telling Iranian President Mahmoud Ahmadinejad to curtail Tehran’s nuclear programme.
President Ahmadinejad is due to visit Delhi next week.
