Talks on the estimated $7bn Iran-Pakistan-India pipeline are at an advanced stage, according to a statement from Pakistan’s foreign ministry.

The Pakistani cabinet ratified a sale and purchase agreement for gas from the scheme, also known as the Peace Pipeline, on 8 January.

India’s participation in the project is still in doubt, however. Talks on the country’s involvement have stalled due to a dispute with Pakistan over pipeline transit fees.

The 2,600 kilometre long pipeline project has also been challenged by Washington, which is trying to pressure Tehran into abandoning its nuclear development programme.
