"Would very much appreciate Saudi Arabia doing their IPO of Aramco with the New York Stock Exchange," the US President tweeted. "Important to the United States!"
The tweet comes as Saudi Arabia prepares to launch its state oil group, on the international stock market. Aramco is the largest energy company in the world, and experts say its equity sale could be the largest in stock market history.
Saudi leaders have considered selling five per cent of the company in an initial public offering (IPO) since early last year. Saudi Crown Prince Mohammed bin Salman is expected to make the final decision as to which foreign stock market – if any – will be able to list shares.
America's bid for the listing is likely helped by Mr Trump's friendly relationship with Saudi Arabian leaders.
Mr Trump travelled to Saudi Arabia in his first official foreign visit as President in May – a symbolic move that was criticised by both Democrats and Republicans at the time. He also welcomed the Crown Prince to the White House in March, in what the administration called a "historic turning point” in US-Saudi relations.
Mr Trump tweeted from Hawaii, shortly before leaving for Japan. The President departed the day before for a 12-day diplomatic tour through Asia – the longest of any sitting president since George HW Bush in 1992.
The tour will take Mr Trump through Japan, South Korea, China, Vietnam, and the Philippines. The President will focus on reducing the nuclear threat from North Korea, advancing international trade, and promoting “a free and open Indo-Pacific region," according to national security adviser HR McMaster.
Mr Trump indicated that he would prioritise the threat from North Korea on the trip, telling Fox News: “We have one problem. That’s called North Korea."
“I must tell you North Korea’s a thing that I think we will solve and if we don’t solve it, it’s not going to be very pleasant for them," he told Fox's Laura Ingraham the day before the trip. "It's not going to be very pleasant for anybody,”
The President appeared preoccupied with the stock market on Saturday, however. Minutes before the Saudi Arabia tweet, he wrote that the market was at its "highest ever," and added that unemployment was the lowest it had been in 17 years.
