U.S. Secretary of State John Kerry arrives in Saudi Arabia late Sunday where he was met by Saudi Foreign Minister Saud al-Faisal.

The kingdom has become frustrated with Washington's perceived inaction in Syria, and is concerned about its diplomatic engagement with Iran and lukewarm attitude toward the military-backed government in Egypt.

A senior Saudi prince last month warned that the kingdom could "shift away" from the United States, suggesting a major strategic change after decades of close military and economic cooperation. In Washington, officials saw the threat as mostly rhetoric.

Kerry will meet King Abdullah Monday.
