Crown Prince Muhammad Bin Salman, deputy premier and minister of defense, arrived here on Wednesday evening on a state visit to Spain.
The prince is not due to sign mega-contracts in France as he did in the United States and Britain in the past month.
The French president defended weapons sales to the Saudi-led coalition fighting in Yemen but said he was concerned by the humanitarian situation, and would host a conference on the issue before the summer.
French officials dismiss suggestions that the lack of lucrative accords reflects a weakening in the relationship.
Human rights groups also question how far the kingdom has come.
The two countries also said the Paris National Opera would help the kingdom develop a national orchestra.
The kingdom revealed on Monday that it would enter short films at the Cannes cinema festival for the first time and send an official delegation to the celebration of often edgy and subversive silver-screen art on the Riviera this May.

Prince Mohammed bin Salman, the 32-year-old heir to the Saudi throne, will wrap up the visit with a gala dinner at the Elysee Palace and formal discussions with Macron on Tuesday evening that are expected to cover the war in Syria.
Macron's role in helping mediate in the Lebanese leadership crisis, which led Hariri to travel to Paris and then rescind his resignation, was seen by analysts as exposing the limits of Prince Mohammed's authority.
After a tense first exchange between the two leaders in Riyadh last November that was dominated by a difference of opinion on how to handle Riyadh's regional rival Iran, Macron and Prince Mohammed sought to get to know each other and work on what they have in common rather than their differences.
