US President Barack Obama will arrive in Riyadh on Friday on an official visit to Saudi Arabia, a report said.

The kingdom is the last leg of Obama's six-day trip, which will include stops in the Netherlands, Belgium, Italy and Vatican City, said the Arab News report.

Obama will hold talks with Saudi King Abdullah on a range of key bilateral and regional issues, the report said quoting Johann Schmonsees, US Embassy spokesman.

“It will be an opportunity to reinforce one of our closest relationships in the region and build on the strong US-Saudi military, security and economic ties that have been a hallmark of our bilateral relationship,” said Johann.

“The two leaders will discuss our ongoing cooperation to advance a range of common interests related to Gulf and regional security, including the situation in Iran and Syria, negotiations between Israelis and Palestinians, countering violent extremism and other issues of prosperity and security,” he said.

Obama is expected to spend one night in Saudi Arabia before he returns to the US on Saturday.
