Pakistan’s Foreign Minister Ishaq Dar said Tuesday his country will not back off from building a much-delayed gas pipeline with Iran.

“We will not let anyone use their veto,” Dar said at a press briefing Tuesday, without naming the United States.

Pakistan and Iran signed a Gas Sales and Purchase Agreement in June of 2009 for a pipeline that would supply 750 million to 1,000 million cubic feet per day of gas to energy-starved Pakistan from Iran’s South Pars Field.

While Iran claimed in 2011 that it had completed its side of the pipeline, construction delays continue on the Pakistani side, primarily for fear of invoking U.S. sanctions.
