Iran's deputy oil minister said on that Pakistan must finance own gas pipeline that would enable it to buy gas from the Islamic republic.
Majedi's remarks come after Pakistan's Oil Minister Shahid Khaqan Abbasi asked Iran to stump up $2 billion (1.45 billion euros) to finish the construction of the pipeline.
The $7.5-billion project launched in 2010 has drawn threats of US sanctions and run into repeated problems, including major financing issues.
"We did not make such a commitment to help Pakistan with $2 billion for the construction of the pipeline," Majedi said, quoted by Fars news agency.
He argued that based on initial agreements each side "must bring its own share" in financing the project, adding the "Pakistanis need Iran's gas and they should accelerate their work."
