President Trump has welcomed the Crown Prince of Saudi Arabia - Mohammed bin Salman - to the White House. It's the 32-year-old Crown Prince's first official visit to the country as heir to the Saudi throne. The two are taking up an array of contentious issues. CGTN'S Roee Ruttenberg reports on the high-profile visit.

The visit of Saudi Arabia's Crown Prince Mohammed Bin Salman, also known as MBS, comes almost one year after the U.S. president visited Riyadh. The Saudi Kingdom was Trump's first foreign stop after he entered the White House. And the ruling royal family pledged to invest tens of billions of dollars in U.S. infrastructure projects, and to purchase American arms and military hardware. On Tuesday, in Washington, Trump - using a bit of show-and-tell - touted the sales.

DONALD TRUMP US PRESIDENT "If you look in terms of dollars: three billion dollars, 533 million dollars, 525 million dollars. That's peanuts for you; we should have increased it."

Some of that will go toward the Saudi-led offensive in Yemen. Now, in its third year, a growing number of U.S. lawmakers are saying: it must end. Some will go to fighting ISIL in nearby Syria and Iraq. The Saudis - playing what Washington's considers to be a crucial role in its coalition. And a large part will go to counter -- what both countries perceive to be - the growing threat from neighboring Iran.

MOHAMMED BIN SALMAN SAUDI CROWN PRINCE "We are here today to be sure that we've tackled all the opportunities and achieve it. And, also, get rid of all the threats facing our both countries and the whole world."

The Saudi prince is on a PR blitz covering several American cities. It's his first official visit to the U.S. since his father consolidated power last year and made Mohammed his heir-apparent. Many in the West have welcomed MBS's more liberal attitude back home in the religiously conservative kingdom. He says he favors greater rights for Saudi women, like driving. And wants to reduce the overall power of the country's clerics. He's pushing to diversify the Saudi economy away from its reliance on oil. And supports a crackdown on the funding of terrorism and corruption. Though, in November, a round-up of some powerful, wealthy players earned the Saudis a strong rebuke from Rex Tillerson, Trump's Secretary of State. On a visit to Riyadh the next month, Tillerson also criticized the Saudi's for their involvement in Lebanon, and for leading a blockade on fellow Gulf kingdom, Qatar.

ROEE RUTTENBERG WASHINGTON, DC "Tillerson is now out of the way. He was fired this month by Trump. And on Tuesday, the Saudi Crown Prince had dinner -- not with Tillerson's apparent replacement, but rather -- with Trump's son-in-law, Jared Kushner. Kushner is charged with leading the president's greater Middle East strategy, which includes isolating Tehran. On that issue, the royal family and the Trump family see eye-to-eye.
