Saudi Arabia and the UK will sign a series of agreements when the kingdom’s crown prince Mohammed bin Salman visits London this week, in deals that diplomats said could be worth more than $100bn.
He is due to have lunch with Queen Elizabeth II on Wednesday and dinner with Prince Charles and the Duke of Cambridge,William, in the evening.
He is also due to meet Prime Minister Theresa May and ministers, including Foreign Secretary Boris Johnson, at the prime minister's residence in Downing Street, Wednesday.
Meetings over the next three days are expected to focus on defense, security and economic ties.
The planned initial public offering (IPO) of state oil giant Saudi Aramco (London is competing with New York to be the stock exchange where the company is listed overseas) is also expected to be discussed.
The U.K. government said Vision 2030 will provide opportunities for British businesses in sectors including education, entertainment and health care "where they have world-class expertise."
"It also includes plans for Saudi Arabia to become a global investment powerhouse and the crown prince's visit will help explore ways in which Saudi Arabia can build on its investment in the U.K. in sectors such as infrastructure," the government added.
