Duterte was accorded full military honors and welcomed by members of the Saudi royal family, led by King Salman himself, to the royal residence in Rawdhat Khuraim.
Explaining the special honors for Duterte, his spokesman Ernesto Abella said the Saudi monarch admired the chief executive’s decisiveness.
The two leaders also held a bilateral meeting attended by members of Duterte’s Cabinet and Senator Alan Peter Cayetano.
Duterte and King Salman also witnessed the signing of agreements for regular consultations between their countries’ foreign ministries and for the protection of overseas Filipino workers.
Saudi Arabia is host to the largest concentration of OFWs.
But Abella said the fate of Filipinos on Saudi death row was not on the agenda of the bilateral meeting.
As for undocumented OFWs covered by a Saudi amnesty, Abella said the Philippine government would shoulder the cost of their repatriation and would charter a plane to take them home.
Duterte is scheduled to meet the business and Filipino communities later Wednesday.
After Saudi Arabia, he will visit Bahrain and Qatar.
