It is not often that the King of Saudi Arabia receives visiting foreign dignitaries at the airport. That precisely is what King Salman did on Wednesday when he went to the Riyadh airport to lay out an ostentatious welcome to Pakistan’s Prime Minister Nawaz Sharif. There is speculation that the Saudi Kingdom is seeking Pakistan’s military support to shore up its internal and external defences amidst mounting regional tensions. No announcements were made after Sharif met King Salman and other senior members of the Saudi Royal family. But security cooperation was reportedly at the top of the agenda.
