MONTREUX, Switzerland/RIYADH (Reuters) - U.S. Secretary of State John Kerry flies to Riyadh this week to try to reassure King Salman that any nuclear deal with Iran will be in Saudi interests, despite the kingdom's fears that it may boost Tehran's backing for Shi'ite Muslim groups in the region.
Convincing Saudi Arabia to accept any agreed nuclear deal is important to President Barack Obama because he needs Riyadh to work closely with Washington on a host of regional policies and to maintain its role as a moderating influence in oil markets.
