ISLAMABAD, Aug. 5 (Xinhua) -- Head of Pakistan's premier intelligence agency, Lt Gen Zaheer ul Islam, has concluded his three-day crucial talks in the United States and has returned to the country, local media reported on Sunday.
The Inter Services Intelligence (ISI) Chief will submit a detailed report of his U.S. trip to Chief of Army Staff General Ashfaq Pervez Kayani, Dawn TV reported.
Islam held meeting on Thursday with Central Intelligence Agency director David Petraeus and held "substantive, professional and productive" talks, the media reported.
It was the first meeting of the ISI and CIA chiefs in a year as cooperation between the two sides had been stopped during the period over certain issues including the unilateral U.S. military action to kill Osama bin Laden in May 2011 and the last November NATO airstrike on two Pakistani army border checkposts that killed 24 Pakistani soldiers.
The ISI Chief had an important policy meeting at the State Department on Thursday with President Barack Obama's special coordinator for Afghanistan and Pakistan, Lt Gen Douglas E. Lute, local media reported.
U.S. Special Envoy Marc Grossman also attended the meeting. Both sides stated their positions on various issues and expressed their desire to rebuild this important relationship, said an official source.
On Wednesday, Gen Islam had met with CIA deputy director Michael J. Morrell at the residence of Pakistan's Ambassador Sherry Rehman.
"Both sides are focusing on increasing intelligence cooperation between the United States and Pakistan," said an official source when asked what was discussed in these meetings.
Senator John Kerry, who chairs the Senate Committee on Foreign Relations, also attended the conversation.
They also discussed various options for dealing with joint concerns in the war against terror.
There were no discussions on operational details as the two intelligence chiefs were dealing with such details at their closed- door meeting at Langley, the CIA headquarters in Virginia, sources said.
Some media reports suggested that the CIA and ISI chiefs agreed on joint operations against the Haqqani network and the Pakistani Taliban in Afghanistan.
