Pakistan is seeking a "civilised" and "even-handed" relationship with Washington like the one that existed between the US and the UK or with India "right now", Prime Minister Imran Khan has said, underlining the role Islamabad could play in the region, including in Afghanistan after America leaves the war-torn country.

Khan made the comments during an interview with The New York Times in which he also expressed his disappointment that his bid to normalise ties with India did not make any progress though he approached Prime Minister Narendra Modi soon after assuming office in August 2018.

In the interview that comes as US President Joe Biden had his first face-to-face meeting with his Afghan counterpart Ashraf Ghan at the White House on Friday, Khan recalled that Pakistan has had a closer relationship with the US than other nations in the region, such as India, and was a US partner in the war against terrorism, Dawn newspaper reported.

"Now, after the US leaves Afghanistan, basically Pakistan would want a civilised relationship, which you have between nations, and we would like to improve our trading relationship with the US,” he said. Asked to elaborate his concept of a civilised relationship, Khan said he was seeking relations like the one that existed "between the US and Britain, or between US and India right now. So, a relationship which is even-handed".

"Unfortunately, the relationship during the war on terror was a bit lopsided," he said.

"It was a lopsided relationship because the US felt that they were giving aid to Pakistan, they felt that Pakistan then had to do US' bidding.

"And what Pakistan did in terms of trying to do the US bidding cost Pakistan a lot … 70,000 Pakistanis died, and over $150 billion were lost to the economy because there were suicide bombings and bombs going on all over the country," he said.

The main problem with this lopsided relationship was that "Pakistani governments tried to deliver what they were not capable of," and it led to a "mistrust between the two countries," Khan said.

"And people in Pakistan felt they paid a heavy, heavy price for this relationship. And the US thought Pakistan had not done enough."

The prime minister said that his government wanted the future relationship to be based on trust and common objectives, including a peaceful and stable Afghanistan.

The US and the Taliban have signed a landmark deal in Doha on February 29, 2020 following multiple rounds of negotiations to bring lasting peace in war-torn Afghanistan and allow US troops to return home, effectively drawing curtains on America's longest war.

Asked if Pakistan will continue to have any strategic relevance to the US after the pullout, Khan said: "I don't know, really. I haven't thought about it in that way, that Pakistan should have some strategic relevance to the US."

Khan said he could not predict the future of the military and security relationship between Pakistan and the US.
