Pasha made a short visit to Washington, arriving on Wednesday and leaving, to meet with Acting CIA chief Michael Morell and other intelligence officials.
The ISI chief had to face tough questions from the US officials regarding Pakistan's cooperation in the war on terror during his meeting with Morell and his staff where they talked about a possible deal about the "rules of engagement" for the CIA officials to operate in Pakistan, according to media reports.
While officials from neither the US nor Pakistan were willing to speak on the record, those privy to the series of meetings between Pasha and Morell, said the meeting was able to address some of the concerns of both sides.
"The US officials prodded Lt Gen Pasha to take action against different militant outfits. Other topics under discussion included the issue of ongoing operations by the Pakistan military in the northern areas; the alleged presence of al-Qaeda leaders, especially al-Zawahiri, and to devise a strategy to share information," the reports said.
Pasha offered Pakistan's cooperation but sought a "no undercovers and no unilateral strikes" understanding from the CIA, the reports said.
The ISI chief was the top Pakistan official to visit US after the killing of al-Qaeda Osama bin Laden at his hideout in garrison town of Abbottabad on May 2.
