Global leaders will fly to Saudi Arabia this weekend to offer condolences on the death of King Abdullah, testimony to Riyadh's important role in energy markets and the fight against Islamist militancy.
US Vice President Joe Biden, Russia's Prime Minister Dmitry Medvedev, Britain's Prime Minister David Cameron, French President Francois Hollande and Japan's Crown Prince Naruhito will meet the new King Salman to offer condolences.
US President Barack Obama is to cut short his visit to India and will travel to Riyadh on Tuesday to pay his respects.
Irish Ambassador to Saudi Arabia Tony Cotter will represent Ireland at a condolence ceremony in Riyadh this evening.
Muslim leaders paid their respects yesterday at Abdullah's funeral in Riyadh.
Some international human rights groups, meanwhile, have called on Western leaders to condemn Saudi Arabia's record of crushing dissent and depriving women and foreign workers of rights instead of praising its late king.
Salman takes charge in Saudi Arabia at a time of deep uncertainty in the kingdom, surrounded by a region in tumult and nervous about both Iranian influence and the spread of Islamist militants.
The kingdom's role in orchestrating Arab support for joint action with Western countries against the Islamic State group has won praise in the US.
Saudi jets have bombed IS targets in Syria, its top clerics have issued repeated denunciations of the militant group despite similarities between its ideology and Wahhabism, and the police have detained thousands of militant suspects in the past decade.
Its role as biggest oil exporter is particularly important at this time of market instability.
Salman pledged yesterday to maintain the kingdom's policies and kept most of Abdullah's cabinet, including the oil, finance and foreign affairs ministers, in place.
Western countries also value the kingdom as an important market for their defence industries.
Salman quickly moved to appoint his son Prince Mohammed, 35, as his own successor as Defence Minister, responsible for big arms contracts.
Saudi Arabia observes no official period of mourning, in keeping with the ascetic traditions of its official Wahhabi school of Sunni Islam.
However, the royal court has announced that it will receive condolences and pledges of allegiance until tomorrow.
Yesterday state television showed princes, Wahhabi clerics, tribal chiefs, military leaders, major businessmen and other dignitaries crowding the royal palace to kiss King Salman's shoulder or hand.
