Saudi Arabia has unveiled plans to build a new city and business zone - a project that will be backed up by more than $500bn (£381bn) in investment. Crown Prince Mohammed bin Salman says the 26,500 sq km (10,232 sq mile) NEOM zone will be developed in the north-west, extending to Egypt and Jordan.
It will focus on nine sectors including food technology and, energy and water. The crown prince has been leading a drive to move Saudi Arabia away from its dependence on oil revenues. In August, the Gulf kingdom launched a massive tourism development project to turn 50 islands and other sites on the Red Sea into luxury resorts. However, the extremely ambitious nature of Mohammed bin Salman's vision is sure to raise questions about how realistic it is, the BBC's economics correspondent Andrew Walker says.
Saudi officials said NEOM would be financed "over the coming years" by the state as well as local and international investors. "NEOM's contribution to the kingdom's GDP is projected to reach at least $100bn by 2030, in addition to its per capita GDP - projected to become the highest in the world," a statement said.
"It is set to become a new vibrant destination" on the coast of the Red Sea and the Gulf of Aqaba, linking Asia, Africa and Europe.The announcement came at an international business conference in Saudi Arabia's capital Riyadh. Egypt and Jordan are yet to comment on the new project.
