US President Donald Trump is set to host Saudi Crown Prince Mohammed bin Salman at the White House on Tuesday for a visit showcasing the countries' deepening security, trade and diplomatic relations.

Here is a look at some of the potential deals that could be discussed.

Military ties

The Trump administration is keen to finalise the sale of dozens of F-35 fighters to Riyadh and the President on Monday said the deal would be going ahead.
