The Iran-Pakistan gas pipeline aims to export a daily amount of 21.5 million cubic meters (or 8.7 billion cubic meters per year) of the Iranian natural gas to Pakistan.

Maximum daily gas transfer capacity of the 56-inch pipeline which runs over 900 km of Iran's soil from Asalouyeh in Bushehr Province to the city of Iranshahr in Sistan and Balochistan Province has been given at 110 million cubic meters. Iran has already constructed more than 900 kilometers of the pipeline on its soil.

Pakistan's President Asif Ali Zardari yesterday said that his country's ties with Iran will not be "undermined" by any international pressure and Islamabad is determined to forge ahead with projects with Tehran, including the gas pipeline.
