He will also meet religious leaders, make a speech at parliament, and visit Southeast Asia's biggest mosque, Istiqlal, on Thursday before a brief trip to Brunei and then an extended break on the Indonesian holiday island of Bali.

Enthusiastic crowds, including tens of thousands of students, lined the route of his heavily guarded motorcade to the presidential Bogor palace.

The king was also greeted by Basuki Tjahaja Purnama, Jakarta's Christian governor, who is on trial for allegedly insulting the Koran. Gen. Syafruddin previously said that almost 10,000 officers will be deployed to secure the visit by King Salman, who will be accompanied by an entourage of around 1,500 men.

During his four-day state visit here, Saudi Arabia and Malaysia signed four Memorandums of Understanding (MoUs) to further strengthen ties between the two nations.

During his trip to Indonesia, the Saudi king will be accompanied by more than 900 people, including ministers, princes and service staff, Alshuaibi said.

King Salman exited his plane at Halim airport in Jakarta using an escalator, with a portable lift carrying him the final meter or so to the ground. It is the first such visit by a Saudi king to the world's largest Muslim populated country since 1970.

President Widodo and King Salman witnessed the signing of agreements on cooperation in areas of fighting crime, trade, investment, fishery, research and technology, high education, culture and health.
