Paragraph:
The relationship between Pakistan and Saudi Arabia is indeed a strong one that goes back decades. The approach of Saudi Arabia towards Pakistan largely revolves around three key components in the present geopolitical context. The first is the military power and nuclear capabilities of Pakistan which addresses the strategic requirements for Saudi Arabia. The second is the economic limitations of Pakistan which can only be addressed by countries like Saudi Arabia since in the recent past Western powers have distanced themselves from Pakistan. The third is the factor of the Islamic identity of Pakistan which completely caters to the idea of working in partnership for the larger welfare of Muslim ummah which remains crucial for Saudi Arabia in the present regional dynamics. Although certain divergences and limitations in this strong alliance are evident especially with Pakistani Prime Minister Imran Khan pulling out from the Kuala Lumpur Summit because of the pressure from Saudi Arabia and Riyadh’s accentuated engagement with India causing discomfort to Islamabad. The long-standing Islamic relationship will continue on the basis of strong strategic, political and economic collaboration that is crucial for both countries as both Saudi Arabia and Pakistan keenly aspire to secure strong regional power postures in the Middle East and South Asia respectively
