WASHINGTON - US President Barack Obama on Wednesday went out of his way to praise two of Saudi Arabia’s top leaders before meeting privately with them at the White House and played down the absence of King Salman, who pulled out of the visit last week.

‘The United States and Saudi Arabia have an extraordinary friendship and relationship that dates back to (President) Franklin Roosevelt,’ Obama said at the start of the meeting with Saudi Arabia’s Crown Prince bin Nayef and Prince Salman in the Oval Office. ‘We are continuing to build that relationship during a very challenging time,’ he said.

Obama said they would discuss how to build on a ceasefire in Yemen and work toward ‘an inclusive govt’ in Arabia’s impoverished neighbour, where Iran-supported Houthi rebels have been under attack by a Saudi-led coalition.

King Salman decided abruptly to skip the White House meeting and a summit of the Gulf Cooperation Council at the president’s Camp David retreat in Maryland outside Washington on Thursday.

The White House has sought to counter perceptions that his absence was a snub that would undermine efforts to reassure the region Washington remains committed to its security against Iran. US officials have said the right leaders were attending the summit, which they portrayed as a working meeting rather than a symbolic get-together.

The Gulf Cooperation Council includes Saudi Arabia, Kuwait, Qatar, Bahrain, the United Arab Emirates (UAE) and Oman. The absence of many top Arab leaders, in addition to King Salman, is viewed as a reflection of frustration with Obama’s pursuit of a nuclear deal with Iran and a perceived U.S. failure to support opposition fighters in Syria.

The president called Saudi Arabia a critical partner in the fight against Islamic State militants. Obama highlighted his interactions with his two guests. ‘On a personal level, my work and the US government’s work with these two individuals on counterterrorism issues has been absolutely critical to maintaining stability in the region but also protecting the American people,’ Obama said. Obama does not have private meetings on his public schedule with the leaders from the other countries, although a dinner is planned on Wednesday for the full group at the White House. Crown Prince bin Nayef said his country attached great importance to the ‘strategic and historic relationship’ with the United States.
