Trump received a royal welcome Saturday as he arrived in Riyadh on the first leg of his first foreign tour since taking office. After meeting with King Salman bin Abdulaziz and other royal family members, he ended the day with a banquet and dancing.

Government officials of both countries say Saudi and US company representatives held talks on business projects worth at least 200 billion dollars.

Saudi Arabia's state-run oil firm, Saudi Aramco, signed 50 billion dollars' worth of agreements with 11 American firms, including General Electric.

US private equity firm Blackstone said Saudi Arabia's Public Investment Fund will provide 20 billion dollars for a new fund for infrastructure projects in the United States.

Stock markets suffered a meltdown on Wednesday after the alleged revelations, resulting in huge losses for almost every one of world’s 500 richest people, according to Bloomberg. 

Facebook co-founder and CEO Mark Zuckerberg took the biggest hit, estimated at more than $2 billion. Shares in the social media giant fell 3.3 percent, but Zuckerberg still holds fifth position on the global rich list with around $62.3 billion, according to the Bloomberg index.

The richest person on the planet, Bill Gates, lost around $1 billion amid the carnage, as Microsoft’s shares suffered the most significant drop in almost a year – 2.8 percent. Still, Gates’ net worth is $86.8 billion, according to Bloomberg.

Gates was fourth on the list in terms of the amount of reduced capital. Jeff Bezos, the co-founder of Amazon.com, the world’s largest online retailer, is second after Zuckerberg based on the size of losses incurred amid the political uproar.

Before the stock market dive, Bezos was second behind Gates in terms of overall wealth. The turmoil saw Amazon shares recede 2.2 percent, however, and he now stands third with a $81.9 billion – a loss of more than $1.7 billion.

Bezos was overtaken on the list by Amancio Ortega, a Spanish business tycoon and chairman of Inditex, the world's largest clothing company, best known for its Zara chain. Ortega lost $355 million, five times less than Zuckerberg’s loss, and is now the second wealthiest person on the planet with $83.2 billion.

Wednesday’s market drop followed US media reports on alleged state secret leaks during the meeting between US President Trump and Russian Foreign Minister Sergey Lavrov last week.

The revelations were dismissed by Russia, with President Vladimir Putin calling them “political schizophrenia.” Earlier, the Russian Foreign Ministry also dismissed the media claims, saying that reading US newspapers can “not only be harmful, but dangerous.”

The eight richest people on Earth are estimated to possess wealth equal to that of the 3.6 billion people who make up the poorest half of humanity.

According to the latest Bloomberg estimates, the top 500 billionaires and millionaires are valued at around $4.9 trillion. A 2016 report by Boston Consulting Group said only 1 percent of the world’s population owns almost half of its wealth, and that the wealth of the rich is only growing.
