Pakistan affirms its relationship with Saudi Arabia as their most "important and bilateral partnership" in the current foreign policy of Pakistan, working and seeking to develop closer bilateral ties with Saudi Arabia, the largest country on the Arabian Peninsula and host to the two holiest cities of Islam, Mecca and Medina and the destination of Muslim pilgrims from across the world.

[11][10] Saudi Arabia has also provided extensive religious and educational aid to Pakistan, being a major contributor to the construction of mosques and madrassas (religious schools) across Pakistan, including the Faisal Mosque in Islamabad, named after King Faisal of Saudi Arabia.

[26] In 2018 Saudi Arabia agreed to establish an oil refinery at Gwadar, with a proposed capacity of 500,000 barrels per day.

[35] Pakistanis face poor treatment from their supervisors, which results in grievance for diaspora population, with some complaints starting right from the airport.

[37][38] It would also help refine and store imported oil for onward transportation to China and develop fuel supply chain for the landlocked Central Asian states.

[20] Saudi Arabia has negotiated the purchase of Pakistani ballistic missiles capable of carrying nuclear warheads.
