US President Barack Obama will meet Saudi Arabias King Abdullah in Riyadh next week to seek his support over the nuclear standoff with Iran and reviving the Israeli-Palestinian peace process. Obama will visit Riyadh on June 3 in a surprise addition to his scheduled three-day trip to Egypt, Germany and France, White House spokesman Robert Gibbs said on Tuesday. Saudi Arabia, the worlds top oil exporter, is a staunch US ally in the region and potentially a key player in the drive for a solution to the Palestinian-Israeli conflict, which Obama has declared a top foreign policy priority. The Obama administration has embraced the 2002 Arab peace initiative, a proposal authored by Saudi Arabia that offered Israel normal ties with all Arab states in return for a full withdrawal from the lands it seized in the 1967 Middle East war, creation of a Palestinian state and a 'just solution for Palestinian refugees.
