A preferential trade agreement and easing of procedures for business visas for Pakistanis will be proposed to Saudi Arabia as part of Prime Minister Imran Khan's vision for carrying out economic reforms.

Besides holding talks with Indian Prime Minister Narendra Modi, the Saudi Crown Prince will also meet President Ram Nath Kovind and Vice President M Venkaiah Naidu during his two-day visit.
"Pakistan will always stand with Saudi Arabia whenever it faces a threat in any form to its security and sovereignty".
Asian countries, he added, "have an important special characteristic - that is, we don't interfere in the internal affairs of other countries".
