Obama seeks Saudi king's advice before Cairo speech

Saudi Arabia wants Obama to get tough with Israel's Netanyahu. Obama has hinted he would like Saudi Arabia to offer some confidence-building measures to Israel.

"I think we have not seen a set of potential gestures from other Arab states, or from the Palestinians, that might deal with some of the Israeli concerns," he told the BBC.

King Abdullah sponsored a 2002 peace plan offering Israel collective Arab recognition in return for an Israeli withdrawal from land occupied in the 1967 war, a Palestinian state with Jerusalem as its capital and a just solution for refugees.

The Saudi adviser said it was "completely unrealistic" to expect any concession from Riyadh, at least until Israel stopped all settlement expansion and accepted the Arab peace plan.

Obama has said he would discuss oil with King Abdullah and would argue that price spikes are not in Saudi interests.

Saudi Arabia, the world's biggest crude exporter, has a nearly 60-year-old bond with the United States based on assured oil supplies in return for U.S. protection for the kingdom.
