Pakistan Prime Minister Imran Khan on Saturday left for his maiden trip to the US to have face-to-face talks with President Donald Trump and reboot bilateral relations that were hit after he publicly criticised Islamabad, cancelled military aid and asked it to do more to fight terrorism.

Khan's visit comes at a time when talks between the US and Afghan Taliban are thought to have entered a decisive phase.

Relations between Pakistan and the US have remained tense during Trump's tenure.

Khan, who is undertaking the three-day trip to the US on the invitation of Trump, will be accompanied by army chief General Qamar Javed Bajwa and Inter-Services Intelligence chief Lt Gen Faiz Hameed.

He would visit the White House on Monday for detailed talks with Trump and would also meet House Speaker Nancy Pelosi before returning on July 23.

Diplomatic sources said that issues like the Afghan peace process, Pakistan government's action against terrorism and terror financing and restoration of military aid to Pakistan would be the highlights of the trip.

Khan is expected to brief President Trump about the steps he has taken to normalise relations with India, especially after the Pulwama terror attack in Kashmir and the Indo-Pak military standoff following the Balakot air strikes, they said.

Khan would stay at the residence of Pakistan's ambassador to reduce costs to the cash-strapped country's exchequer.

He would meet Pakistan diaspora, heads of IMF and World Bank, investors, media people, editors and also give a talk at the US Institute of Peace.

Foreign Office Spokesperson Muhammad Faisal earlier this month said that the 'agenda of the meeting is being developed through diplomatic channels' but the focus will be to 'refreshing bilateral relations'.

Efforts for arranging the Imran-Trump meeting have been going on for months. However, The Express Tribune reported that Saudi Crown Prince Mohammed bin Salman played a key role in arranging the meeting.  -- PTI
