(Bloomberg) -- Saudi Arabia has scaled back its medium-term ambitions for the desert development of Neom, the biggest project within Crown Prince Mohammed bin Salman's plans for diversifying the oil-dependent economy, according to people familiar with the matter.

By 2030, the government at one point hoped to have 1.5 million residents living in The Line, a sprawling, futuristic city it plans to contain within a pair of mirror-clad skyscrapers. Now, officials expect the development will house fewer than 300,000 residents by that time, according to a person familiar with the matter.
