"Pakistan has consistently maintained that the Iran nuclear issue should be peacefully resolved through dialogue," the Foreign Office said.
"As a neighbouring country, we have also reiterated that reciprocal confidence-building measures relating to Iran's nuclear programme auger well for peace and security in our region," it said.
The Foreign Office said Pakistan looks forward to the expeditious and smooth implementation of the provisions of the comprehensive nuclear agreement by all signatories.
The negotiations, which began in 2006, aimed at scaling back of Iran's sensitive nuclear activities to ensure it can't build a nuclear weapon, had continued beyond the June 30 deadline.
The agreement is expected to draw curtain over wrangling between Iran and the US and pave way for new cooperation, having deep impact on the Middle Eastern region.
