Türkiye and Saudi Arabia have signed a series of deals encompassing investment, the defence industry, energy and communications.
The agreements were signed after delegation meetings led by Turkish President Recep Tayyip Erdogan and Saudi Crown Prince Mohammed bin Salman in the Saudi city of Jeddah.
President Erdogan earlier had a meeting with the Saudi crown prince behind closed doors at Al Salam Royal Palace.
The Turkish leader arrived Monday in Saudi Arabia as part of a three-day Gulf tour to strengthen ties.
On the first leg of his trip, Saudi Foreign Minister Faisal bin Farhan Al Saud and other officials welcomed Erdogan at the airport in Jeddah.
The president is being accompanied by members of his cabinet and other Turkish officials.
Following the talks, Erdogan presented a Pamukkale white Togg to the Saudi crown prince.
The two leaders examined the vehicle in the courtyard of the palace.
Upon concluding the visit, Erdogan returned to his hotel in the Togg, which Crown Prince bin Salman drove.
After Saudi Arabia, Erdogan will visit Qatar and the United Arab Emirates, respectively.
