In a meeting with Pakistani Foreign Minister Makhdoom Shah Mahmood Qureshi in Islamabad on Friday, Zarif said Tehran sets no limitation to the expansion of ties with Islamabad.
Pakistan is cooperating with Beijing's "Belt and Road" initiative, but the country's financial situation remains hard.
Experts believed that the Pakistani prime minister's quest for dialogue with India has led to a debate in India and many Indians also want their government to resume comprehensive dialogue with Pakistan.
US President Donald Trump announced in May his country's withdrawal from the nuclear deal that triggered criticism by the United Nations and several countries.
Under the deal, Iran undertook to put limits on its nuclear program in exchange for the removal of nuclear-related sanctions.
It was agreed that the next round of Bilateral Political Consultations and the Joint Economic Commission will be held at early date. However, a source from the Pakistani side told Xinhua that it can not be called a deadlock as a two-member Pakistani delegation is expected to visit India in September for the next phase of the talks.
"As regards JCPOA, while supporting Iran's principled stance, Qureshi expressed the hope that remaining parties to the Agreement would uphold their commitments in letter and spirit", it said.
The Prime Minister stressed upon the need for improving governance, service delivery, transparency and promoting merit at all levels in order to capitalize the enormous potential of the country.
Speaking to television anchorpersons here, the prime minister said Pakistan can not fight with the USA and wanted good ties with the superpower.
Imran Khan said Pakistan is one of the seven most affected countries by global warming and prime objective of this drive is to make the country green and counter the negative impact of global warming.
They also called for enhanced efforts to establish peace and stability in all regional countries and fight against terrorism and extremism. Both Pakistan and Iran are members of ACD and Iran now holds the chair of the organisation.
According to figures released by the PM, Pakistan's current account deficit is $18 billion while foreign exchange reserves are just over $10 billion; barely enough for two months of imports.
