U.S. Vice President Dick Cheney is holding talks with Saudi King Abdullah that are expected to include efforts to stabilize the world's oil market.
Cheney arrived in Saudi Arabia Friday.
The talks follow turmoil on energy markets that saw crude surging to the highest price on record, followed by an easing of prices in recent days.
U.S. officials say Cheney will also encourage Saudi Arabia to bolster ties with Iraq to counter Iran's growing regional influence.
Saudi Arabia and some other Arab states have not yet sent ambassadors to Baghdad.
On Thursday in Afghanistan, Cheney met with Afghan President Hamid Karzai. The two officials urged NATO countries to step up their commitment to help Afghanistan fight extremists and recover from years of war.
Vice President Cheney is on a tour of the region, including stops in Oman, Israel, the West Bank and Turkey.
