Saudi Crown Prince Muhammad Bin Salman is heading, on Friday, to the US city of Seattle, Washington State’s largest city, often called the Emerald City, and home to a huge tech industry. The trip is of equal importance to his visit to Washington, Boston and New York. Prince Muhammad Bin Salman is set to spend a few days in Seattle, where about 500 giant companies, including Boeing, Microsoft, Costa, Amazon and Starbucks, have their headquarters - adding to that its significant value for the US economy, technology and tourism. The Crown Prince met earlier with 40 executive officials of several major US companies and reviewed the importance of working on joint projects with Saudi Arabia. — Al Arabiya English
