WASHINGTON, March 10 (Reuters) - Vice President Dick Cheney leaves on Sunday for the Middle East where he will raise U.S. concerns about record-high oil prices and try to push Israeli-Palestinian peace talks forward, the White House said.

Cheney will visit Saudi Arabia, Israel, the West Bank, Turkey and Oman in a trip expected to last about a week or more, his office said on Monday.

"His goal is to reassure people that the United States is committed to a vision of peace in the Middle East," U.S. President George W. Bush said after meeting with Poland's prime minister at the White House.

Cheney will also take the message "that we fully see the threats facing the Middle East, one such threat is Iran, and that we will continue to bolster our security agreements and relationships with our friends and allies," Bush said.

Cheney's visit to Israel and the West Bank follows one by Secretary of State Condoleezza Rice to the region last week, when she urged leaders to move forward with peace talks that were dealt a blow by violence in Gaza and Israel.

Rice was set to meet Israeli Foreign Minister Tzipi Livni in Washington later on Monday as part of increased U.S. diplomatic efforts since Palestinian statehood talks were launched in Annapolis, Maryland, last November.

Bush, who visited Israel this year for the first time as president, has said he is optimistic a peace deal can be reached before he leaves office in January 2009.
