The article Persian Pipeline also mentioned the method for its protection along the hostile territory by establishing mini battalion-size cantonments along its proposed route through Balochistan/Sindh.

[4][5] The project was conceptualized in 1989 by Rajendra K. Pachauri in partnership with Ali Shams Ardekani and Sarwar Shar, former Deputy Foreign Minister of Iran.

[7] In 2004 the project was revived after the UNDP's report Peace and Prosperity Gas Pipelines by Pakistani petroleum engineer, Gulfaraz Ahmed, was published in December 2003.

[8] In February 2007, India and Pakistan agreed to pay Iran US$4.93 per million British thermal units (US$4.67/GJ) but some details relating to price adjustment remained open to further negotiation.

[11] In 2009, India withdrew from the project over pricing and security issues, and after signing a civilian nuclear deal with the United States in 2008.

[19][20][21] According with Javad Owji, managing director of the National Iranian Gas Company, the pipeline in Pakistan is expected to be constructed in 22 months with the participation of Iran.

[22] On 27 May 2013, Iranian deputy minister for petroleum, A. Khaledi, in a letter to the Pakistan government expressed concern over the delay in the start of the Pakistani portion of the pipeline.

Pakistan still hasn't officially nominated Tadbir Energy and local sub-contractors to begin work on the Pakistani half of the pipeline.

[29] During the year 2017, India is planning to disassociate from this pipeline project and working on cheaper independent under sea pipe line directly from Iran.

[31][32] On 23 February 2024, Pakistan approves construction of Iran–Pakistan gas pipeline amid fear of a potential 18 billion US dollar penalty for failing to complete the project on time.

[33] In August 2024, Iran threatened to move the case to International Court of Arbitration due to Pakistan's failure to construct the pipeline by the end of 2024.

If canceling the project, Pakistan would receive assistance from the United States for construction of a liquefied natural gas terminal and importing electricity from Tajikistan through Afghanistan's Wakhan Corridor.

[40] On 13 March 2012 Pakistan's ministry of finance announced that private investors were showing diminished interest and that the government might have to impose a tax on consumers, or seek government-to-government arrangements with Iran, China and Russia to build the pipeline.

[40] On 15 April 2012, it was reported through unnamed diplomatic sources in Islamabad that Saudi Arabia was offering to deliver an "alternative package" to Pakistan if the country abandoned its cooperation with Iran.

[43] In late October 2013, Sustainable Policy Development Institute published a report in which the proposed pipeline was termed as "death sentence" for Pakistan.

[48] As there are concerns over the pipeline being attacked by Baluchi insurgents, an alternative offshore route from Iran to the maritime boundary between India and Pakistan off Kutch was proposed.

[53] Authorities blamed Lack of safety measures and old infrastructure for the Thursday 14 March 2019 explosion in a gas pipeline near the city of Mahshahr in southern Iran.

[16] However, on 13-December-2013, Pakistan's Minister for Petroleum and Natural Resources Shahid Khaqan Abbasi said that Iran refused to fund the project citing 'acute financial constraint' as the reason.

Both sides have decided to constitute a working group which would re-establish in two months the new parameters for the projects, including a new time-frame and other important issues involving financing of pipeline to be laid down in the territory of Pakistan.
