WASHINGTON (Reuters) - U.S. Treasury Secretary Steven Mnuchin and presidential adviser Jared Kushner will lead Washington’s delegation to an annual financial conference in Saudi Arabia, government sources said on Tuesday.

The conference comes a year after U.S.-based journalist Jamal Khashoggi was murdered inside the Saudi consulate in Istanbul, prompting a global outcry.

State Department Iran adviser Brian Hook and Kushner adviser Avi Berkowitz plan to join Mnuchin and Kusher at the Future Investment Initiative in Riyadh, a senior administration official told Reuters.

Energy Secretary Rick Perry, who is due to step down on Dec. 1, will also attend, a second government source said.

Perry has held a series of private talks with Saudi officials, including former energy minister Khalid al-Falih, on the use of U.S. technology to build civilian nuclear power plants in the kingdom.

Kushner will attend the conference after leading a delegation to Israel, Reuters reported Oct. 17. Mnuchin’s plans to attend were first reported by Quartz.

The conference, nicknamed “Davos in the Desert” seeks to draw global investment banks and financiers to Riyadh to interact with Saudi officials and drum up investment for projects in the region. It will be held from Oct. 29 to 31 at the Ritz Carlton in Riyadh.

Last year executives including J.P. Morgan Chase JPM.N Chief Executive Jamie Dimon and Ford Motor Co F.N Chairman Bill Ford pulled out of the October conference, after Khashoggi's Oct. 2 disappearance.

The incident led to U.S. Treasury sanctions on 17 Saudi individuals and a Senate resolution blaming Saudi Arabia’s crown prince. But Saudi officials, including Prince Mohammed, later blamed Khashoggi’s death and reported dismemberment on rogue officials.
