Khan said that his government wanted to prosecute whoever was involved in the terror strike as it was in "Islamabad's interest to resolve the matter".
This week, Islamabad issued a statement U.S. President Donald Trump's decision to make political reconciliation between the Afghan Taliban and Kabul the primary goal of America's strategy to end the more than 17-year-old war in Afghanistan.
He said peaceful Afghanistan was in the interest of Pakistan, adding that Afghanistan is one of the few countries with which Pakistan has a trade surplus.
"If we left precipitously right now I do not believe they would be able to successfully defend their country", he said, adding that "the operational military situation is largely stalemated". "Bear in mind that about 40 per cent of Afghanistan is now out of the government's hands".
Pakistan Prime Minister Imran Khan has said that India's ruling party is anti-Muslim and anti-Pakistan and he hopes after the elections in India are over, talks with India can resume.
"It was humiliating that we were losing our soldiers and civilians and (suffering terrorist) bomb attacks because we were participating in the U.S. war, and then our ally did not trust us to kill Bin Laden", he said, adding that the USA "should have tipped off Pakistan". "We would like a proper relationship with the United States".
"The last thing we want is to have chaos in Afghanistan".
Speaking about Afghan refugees in Pakistan, he said, "we have 2.7 million Afghan refugees still living in Pakistan".
If Pakistan had stayed neutral after the September 2001 terror attack in the United States, Pakistan would have saved itself from devastation, Khan said.
"I have never understood these accusations [that Pakistan is harboring Taliban leaders]".
Nevertheless, he did not discount the possibility that Afghan Taliban jihadis are freely moving across the Afghanistan-Pakistan border. The exchange was about being blamed for deeply flawed US policies - the military approach to Afghanistan'.
Some 14,000 US soldiers are now serving in Afghanistan, and McKenzie couldn't say how much longer the United States would remain in the country.
Army spokesman Major-General Asif Ghafoor told reporters in Rawalpindi, where the military is headquartered, that Pakistan has long called for resolving Afghan conflict through political means and a USA -initiated peace process has gained momentum lately.
The Pakistan prime minister, in an interview to The Washington Post, his first to a foreign publication, said that his country wants "something done about the bombers of Mumbai", while tacitly acknowledging that the attack of November 2008 originated from Pakistani soil. The Pakistani leader insisted there "are no sanctuaries in Pakistan".
